Why This Chapter Takes Your Breath Away: The Mystery Unveiled + Paul's Most Profound Prayer

Ephesians 3 is the theological summit of prayer in the whole letter, and one of the deepest prayers in the New Testament. If the praise of 1:3–14 is a bird's-eye declaration "surveying from eternity," and chapter 2 is the double act of "from death to life, two becoming one," then chapter 3 distills the "plan" and the "accomplishment" of the first two chapters into two concentrated themes: first, the revelation of the "mystery" (3:1–13); second, the unfolding of "Paul's second prayer" (3:14–21). The first half of the chapter explains "what God has done." The second half prays, "Can you personally experience all of this?" This is the New Testament's finest example of the transition from doctrine to experience.

Within the six major sections of Ephesians, this chapter forms the closing summit of the doctrinal section (chapters 1–3). The first two chapters laid the groundwork. Chapter 1 presented the golden chain of election, predestination, redemption, and sealing (from the eternal perspective), along with Paul's first prayer for "the spirit of wisdom and revelation" (1:15–23). Chapter 2 presented the double act of "from death to life" (2:1–10) and "two becoming one" (2:11–22). Chapter 3 gathers all of this into a single word, "mystery": "that the Gentiles are fellow heirs, and fellow members of the body, and fellow partakers of his promise in Christ Jesus" (3:6). Then Paul takes the posture of "bowing his knees" (3:14) and prays that the believers would personally experience everything the first two chapters have taught. This is Paul's second prayer (3:14–21).

This chapter has four theological high points that serve as hinges:

This chapter's place in the Reformation and in the history of church renewal:

Context

Chapter 2 revealed God's double act in Christ: raising the dead to life (2:1–10) and uniting Jew and Gentile into one (2:11–22). Chapter 3 picks up the "unity" theme and unveils its deeper cause. This unity is a "mystery" that God hid from the creation of the world, now made public through Paul's apostolic ministry, so that even the heavenly powers might see God's manifold wisdom. The chapter concludes with Paul's second prayer (3:14–21), which corresponds to his first prayer (1:15–23), forming the twin wings of the doctrinal section. The first wing prays for "knowing" (the spirit of wisdom and revelation); the second wing prays for "experiencing" (being personally filled with the love of Christ).

The chapter contains a fascinating grammatical "interruption." Paul begins at 3:1, "For this cause, I, Paul ...," about to launch into prayer. But mid-sentence he veers off course. He needs first to explain why he is qualified to speak about this "mystery," so he inserts a self-description (3:2–13). Only at 3:14 does he pick up the prayer again with "For this cause." This grammatical detour lets readers first understand Paul's unique calling before hearing his prayer. Paul's thought is like a tree: the trunk (prayer) grows a branch (the mission self-description), and the branch returns to the trunk.

The Narrative Unit It Belongs To

Ephesians 3 is the closing chapter of the doctrinal section (chapters 1–3). Chapter 1 surveys God's eternal plan from above (election, predestination, sealing); chapter 2 looks up from humanity's present condition (from death to life, two becoming one); chapter 3 fixes the focus on Paul's mission and prayer. He is the steward of this "mystery" and the intercessor who asks that the readers would "be able to comprehend." The doxology of 3:20–21 is the high point of the first half of the book, framing the whole "in Christ" doctrinal section together with the praise of 1:3–14, so that the two doxologies form an inclusio at the beginning and the end.

Paragraph Structure

The chapter has four sections:

The Whole Chapter's Core Message

This chapter tells the reader that from eternity God has had a "mystery" plan, now made manifest to the universe through the church; and every believer is invited to "personally experience" all of it, to experience Christ dwelling within, the four dimensions of love, and the filling of God's fullness.

"Mystery" is the core word of the chapter. In the Greek mystery religions, "mystery" referred to secret rites known only to an initiated elite. Paul appropriates the word but completely inverts its meaning. The Christian "mystery" is not hidden for a few but "made plain to everyone" (3:9). It is not entered through ritual but proclaimed openly through the gospel. The content of the mystery is also stunning: "Gentiles" (a group almost entirely excluded in the Old Testament) are now completely equal with Jews, "fellow heirs, fellow members of the body, fellow partakers of the promise." This mystery is great not only because it overturns the priestly hierarchy of Second Temple Judaism, but because it elevates the church to cosmic significance. In 3:10, "through the church the manifold wisdom of God" is made known to the heavenly powers. The church's existence serves not only earthly people; it is the theater where angels observe God's wisdom.

This chapter previews the highest dual track of Christian spirituality: "knowing" (the mind) and "experiencing" (the heart). Paul's first prayer (1:15–23) emphasizes "knowing" (asking for the spirit of wisdom and revelation); his second prayer (3:14–21) emphasizes "experiencing" (asking for Christ's indwelling, the filling of love). Neither can be neglected. Experience without knowledge is shallow; knowledge without experience is dry. Paul's goal is "full of the fullness of God," and this is no prize for some "special spiritual stage." It is the ultimate destination toward which every believer truly in Christ may travel.

Pastor's Heart

Brothers and sisters, Ephesians 3 was written for the believer who feels "not good enough, whose prayers aren't big enough, whom God has forgotten." This chapter is for you.

Paul wrote these words from prison. Chains clinked on his wrists, yet the content of his prayer was not "God, get me out of here," but "May you be strengthened in your inner being," "May you comprehend how wide and long and high and deep Christ's love is." A prisoner praying for free people to receive a greater freedom, not of the body but of the spirit. This is the lesson Paul teaches us about prayer: the deepest desire in prayer is to be filled with God, more than to change our circumstances. If this week you also find yourself in some kind of "prison" (a hospital bed, unemployment, a broken relationship, uncertainty about the future), follow Paul's example. Do not stop praying; redirect the prayer inward: "Lord, fill me with yourself in this very situation."

You might feel too small, too unqualified to carry God's grand plan. Paul called himself "less than the least of all saints." The Greek ἐλαχιστοτέρῳ (elachistoterō) is a grammatically irregular "even-smaller-than-the-smallest," a word that does not exist, deliberately coined by Paul to express how he saw himself. He once persecuted the church (1 Corinthians 15:9); now, by grace, he has become an apostle. The greater the grace, the lower his self-assessment. Yet God chose precisely this man to proclaim "the unsearchable riches of Christ." God's logic in using people has never been "choose the strongest person for the greatest task," but "let the most undeserving person experience the greatest grace," so that everyone may know the credit belongs not to the person but to God. You do not need to be "qualified" first before God can use you. Your "not enough" is exactly the stage where grace shines brightest.

Have you ever come to prayer not knowing what to ask for? Paul gives you a "prayer list": strength in the inner being (renewal of inner life); Christ's indwelling (not a passing guest but the homeowner); the four dimensions of love (width, length, height, depth, spanning every dimension); the filling of all God's fullness (the container filled with the source). This is the deepest prayer in the New Testament, yet it was not prepared for "a spiritual elite." Paul prayed it for "all the Ephesian believers," including the most ordinary brothers and sisters. If you do not know what to pray for yourself, copy Paul's prayer; ask God, word for word, to accomplish in you every item listed in 3:16–19.

"Width, length, height, and depth" is not a geometry problem. Length: Christ's love outlasts your whole life. Width: Christ's love is wider than your failure. Height: Christ's love is higher than your fear. Depth: Christ's love is deeper than your shame. In no dimension can anything exceed Christ's love. And Paul deliberately says we comprehend "with all the saints," meaning this love is too vast for one person to fathom alone. You need the church; you need the testimony of others to complete what you can experience. When you are weak, another's faith becomes your eyes. When you are lost, another's prayer becomes your compass. This is why isolated believers are the easiest to topple: separated from the community, you cannot see the full dimensions of Christ's love.

Finally there is 3:20, "God is able ... above all that we ask or think." This verse does not promise that God will give you a better car or a better job. It says that God's plan for your life is better than the best version you could imagine. Your imagination has a ceiling, but God's wisdom and power have none. The Greek hyperekperissou ("super-out-of-abundantly") uses three stacked intensifiers; Paul piled up three "super" prefixes in Greek to express "really, really, truly more than you think." When you feel that "God can probably only do this much," hear Paul's reminder in 3:20: you have made God small again. What he can do far exceeds what you can ask; what he can accomplish far exceeds what you can imagine, because "his wisdom is manifold" (polypoikilos, "multi-colored"), and he always has a way you never thought of.

Reflection Questions

  1. Paul called himself "less than the least of all saints," yet God still used him to accomplish a great mission. Have you held back because you feel "not qualified"? How does God work in your "not enough"?

  2. Paul prayed that believers would "comprehend Christ's love with all the saints"; comprehending Christ's love requires the community. In what moments have you experienced Christ's love more deeply through brothers and sisters? Conversely, when you grow distant from the church, how does your sense of Christ's love change?

  3. "God is able to do above all that we ask or think." In your life, has there been something God did better, more unexpectedly, than what you first asked for? Do you often "make God small" in your prayers?

① 3:1-6 · The Revelation of the Mystery

Where this section stands: The end of chapter 2 has just declared "two becoming one" and "the unity of the temple" (2:21–22). This section begins with "For this cause, I, Paul" (3:1), turning toward prayer, but the words veer off mid-sentence. Paul first needs to explain why he is qualified to speak about this "mystery," so he inserts a self-description (3:2–13), and only at 3:14 does he pick up the prayer again with "For this cause." This is the section with the highest concentration of the word "mystery" in Ephesians, appearing four times (3:3, 3:4, 3:6, 3:9). Adding 1:9, 5:32, and 6:19, the letter uses the word six times in all, the densest usage among Paul's letters.

3:1 "For this cause I, Paul, am the prisoner of Christ Jesus on behalf of you Gentiles,"

Ephesians 3:1(World English Bible)

"For this cause" (Τούτου χάριν, toutou charin, "for this reason") points back to chapter 2's just-declared "two becoming one" and "built together for a dwelling place of God in the Spirit" (2:22). Paul's impulse to pray was ignited by the grandeur of the "mystery." He cannot simply finish teaching doctrine and put down the pen; he must pray for the readers, that they would personally experience all of it.

"The prisoner of Christ Jesus on behalf of you Gentiles" (ho desmios tou Christou Iēsou hyper hymōn tōn ethnōn). The word δέσμιος (desmios) means "prisoner, captive." Paul was writing from Roman imprisonment (Acts 28:30–31). He does not call himself "Rome's prisoner" but "Christ Jesus's prisoner." Behind the chains stands a higher sovereignty. Paul sees his imprisonment not as failure but as being "for Christ"; he belongs directly to Christ, and even his chains are Christ's. This echoes Philippians 1:13 ("my chains are for the cause of Christ") and Philemon 1 ("Paul, a prisoner of Christ Jesus").

"On behalf of you Gentiles" is a deeply significant clarification. The direct cause of Paul's suffering was precisely his proclamation of the gospel of "Jew-and-Gentile unity." Acts 21:28–29 records that Jews in Jerusalem accused Paul of "bringing Gentiles into the temple" (though this was a misunderstanding), triggering a riot that led to his arrest. Paul was chained and escorted to Rome precisely because he refused to surrender the Gentiles' complete equality in Christ. So Paul's chains are the price of the "Gentile gospel," and this sentence lets the Gentile readers in Ephesus feel directly that Paul paid for their "sonship" with his freedom.

There is something else worth noting: in Greek this sentence actually has no main verb (only "For this cause, I, Paul ... on behalf of you Gentiles"); Paul's prayer verb has been "interrupted." Translations supply something like "I pray for you" to complete the sense, but this grammatical "incompleteness" is the very marker of the inserted self-description in this section. Paul must finish telling of his mission before he returns to the prayer (3:14).

3:2-3 "if it is so that you have heard of the administration of that grace of God which was given me toward you; how that by revelation the mystery was made known to me, as I wrote before in few words,"

Ephesians 3:2-3(World English Bible)

"If it is so that you have heard" (εἴ γε ἠκούσατε, ei ge ēkousate, "if indeed you have heard") implies that the recipients may not all have known Paul personally. This is one piece of indirect evidence for the view that Ephesians was a circular letter (several early manuscripts lack "in Ephesus," ἐν Ἐφέσῳ, at 1:1). If it were written to the Ephesian church, where Paul had spent three years (Acts 19:10), he would not use this "perhaps you have heard" tone.

"Mystery" is a core concept in Paul's letters. It does not mean "something incomprehensible" but "a plan of God previously hidden and now revealed." It is not that reason cannot grasp it, but that reason cannot discover it; it must be made known by revelation. The word carried a special meaning in the Greek mystery religions (such as the Eleusinian Mysteries and the cult of Mithras), referring to secret rites known only to an initiated elite. Paul appropriates the word but completely inverts its meaning. The New Testament "mystery" is never "hidden"; it is "the previously concealed plan now revealed," proclaimed openly to all rather than a secret of a few.

"Made known to me by revelation." Here "revelation" carries the sense of "lifting the cover," stressing that this mystery was not something Paul figured out for himself. Apostolic authority rests on God's direct revelation. This is the same theology as Galatians 1:11–12: "the Good News which was preached by me ... I did not receive it from man, nor was I taught it, but it came to me through revelation of Jesus Christ." Paul's apostleship was not "commissioned" by the Jerusalem apostles after the Damascus road; it was revealed by Christ himself. This is the heart of Paul's doctrine of apostleship.

"As I wrote before in few words" may refer to 1:9–10 (chapter 1 already touched briefly on the "mystery"), or to Paul's earlier letters (such as Galatians 3:28, "there is neither Jew nor Greek ... you are all one").

3:4-5 "by which, when you read, you can perceive my understanding in the mystery of Christ; which in other generations was not made known to the children of men, as it has now been revealed to his holy apostles and prophets in the Spirit;"

Ephesians 3:4-5(World English Bible)

"When you read" (πρὸς ὃ δύνασθε ἀναγινώσκοντες). Paul expected his letter to be read aloud in public assembly (cf. Colossians 4:16, "you also read the letter"; 1 Thessalonians 5:27, "I solemnly charge you by the Lord that this letter be read to all the holy brothers"). In the early church, "reading Scripture" was often "hearing Scripture," the congregation listening as someone read the apostolic letters aloud.

"In other generations was not made known" (ἑτέραις γενεαῖς οὐκ ἐγνωρίσθη, heterais geneais ouk egnōristhē). The Old Testament had signs, shadows, and prophecies:

But that Jew and Gentile would be completely equal, fused into one body, was never explicitly disclosed in the Old Testament. The Old Testament picture was always "Gentiles coming to join Israel" (like naturalized sojourners); the New Testament "mystery" is "Gentiles and Jews equally fused into one body in Christ," a completely new structure the Old Testament never imagined.

"As it has now been revealed ... in the Spirit" (hōs nyn apekalyphthē en pneumati). The unveiling of the mystery is not academic archaeology but the active work of the Holy Spirit, and the recipients are a specific group, "his holy apostles and prophets." Note that "prophets" here does not mean Old Testament prophets but the office of "prophets" in the New Testament church (echoing 2:20, "built on the foundation of the apostles and prophets," and 4:11, "he gave some to be apostles, and some prophets"). They are the recipients and transmitters of New Testament revelation.

3:6 "that the Gentiles are fellow heirs, and fellow members of the body, and fellow partakers of his promise in Christ Jesus through the Good News,"

Ephesians 3:6(World English Bible)

This is the mystery's content in maximum concentration. Paul fires three syn- prefix compound words in rapid succession; in Greek they ring like three strokes of a bell.

English Greek Literal Meaning
Fellow heirs συγκληρονόμα (synklēronoma) syn ("together") + klēronomos ("heir"): co-inheriting
Fellow members of the body σύσσωμα (syssōma) syn ("together") + sōma ("body"): belonging to the same body
Fellow partakers συμμέτοχα (symmetocha) syn ("together") + metochos ("sharer"): co-sharing

"Fellow heirs" (συγκληρονόμα (synklēronoma)) are not a branch family receiving leftovers but full-status heirs, inheriting the "promise" on completely equal legal footing with Jewish believers. This word appears only three times in the New Testament (Romans 8:17, Ephesians 3:6, Hebrews 11:9). Romans 8:17 uses it for "we are ... fellow heirs with Christ"; Ephesians 3:6 uses it for "the Gentiles are fellow heirs with the Jews." Both emphasize "equal standing."

"Fellow members of the body" (σύσσωμα (syssōma)) is a word Paul may have coined; it has no occurrence in Greek literature before him. To express the completely new reality of Jew and Gentile fused into "one body," he minted a new term. This connects to 4:4 ("there is one body") and 2:16 ("that he might reconcile them both in one body to God through the cross"). "Body" (σῶμα (sōma)) is the core ecclesiological image of Ephesians.

"Fellow partakers" means co-sharing all of God's promises in Christ, including the gift of the Spirit (1:13), the inheritance (1:14), resurrection (2:6), and adoption (1:5). The Gentiles' status as "outsiders" in the Old Testament is completely reversed; now there is no promise that Gentiles cannot share.

"Through the Good News" (διὰ τοῦ εὐαγγελίου, dia tou euangeliou) is the channel. Not through circumcision, not through law-keeping, not through cultural assimilation, but solely through the gospel. This phrase answers the entire debate of Galatians. The Judaizers in Galatia demanded that Gentile believers also be circumcised and keep the law to be "truly saved"; in both Galatians and Ephesians Paul firmly rejects this added condition. The gospel's "entrance" is the same for everyone: faith, the gospel.

② 3:7-13 · Paul's Mission

Where this section stands: From "the content of the mystery" (3:6, the three syn- words) the argument advances to "the herald of the mystery" (this section). Paul describes his mission on three levels:

  1. Qualification: "less than the least of all saints" (3:8)
  2. Content: "the unsearchable riches of Christ" (3:8)
  3. Goal: "that now ... the principalities and the powers might know the manifold wisdom of God" (3:10). This section is the summit of Ephesians' cosmic ecclesiology: the church serves not only earthly people; it is the theater where angels observe God's wisdom.

3:7 "of which I was made a servant, according to the gift of that grace of God which was given me according to the working of his power."

Ephesians 3:7(World English Bible)

"Servant" (διάκονος, diakonos) is the Greek word for "servant, minister" (the same root as the office of "deacon"). Paul describes himself with this word, not as "master" or "commander" but as "servant." This matches 2 Corinthians 3:6 ("he made us sufficient as servants of a new covenant") and Colossians 1:23 ("I, Paul, was made a servant of this Good News"). The heart of Paul's apostleship is not authority but service; he is the deliverer of the gospel, not its owner.

"According to the gift of that grace" and "according to the working of his power." Paul twice emphasizes that his ministry is entirely gift and entirely powered by God's might. "Gift" (δωρεά (dōrea), a free present) and "power" (dynamis) name the two ends: one is the source (grace, not self-appointment), the other is the engine (divine might, not self-effort). Paul "zeroes out" his ministry from both ends, relying neither on merit (grace) nor on talent (power). This is the same theology as 1 Corinthians 15:10: "by the grace of God I am what I am ... yet not I, but the grace of God which was with me."

3:8 "To me, the very least of all saints, was this grace given, to preach to the Gentiles the unsearchable riches of Christ,"

Ephesians 3:8(World English Bible)

"Less than the least of all saints" (ἐλαχιστοτέρῳ πάντων ἁγίων, elachistoterō pantōn hagiōn). The form elachistoterō is built from elachistos ("least," a superlative) plus the comparative suffix -teros ("more"), a grammatically irregular "comparative of the superlative," equivalent to "even smaller than the smallest" or "less than the very least." Paul deliberately coined a word that does not exist to express how he saw himself: the man who once persecuted the church (1 Corinthians 15:9, "I am the least of the apostles, who is not worthy to be called an apostle, because I persecuted the church of God"), now an apostle by grace. The greater the grace, the lower his self-assessment.

Paul's self-assessment follows a "three-stage descent":

The closer Paul drew to the Lord, the more clearly he saw his own smallness. This is not false humility but the normal reaction of someone who has truly seen God's glory. It follows the same spiritual logic as Isaiah, who after his vision immediately said, "Woe is me! For I am undone, because I am a man of unclean lips" (Isaiah 6:5). People who are self-righteous tend to rate themselves highest; those who have "truly seen God" inevitably rate themselves lowest.

"The unsearchable riches of Christ." The word ἀνεξιχνίαστος (anexichniastos) means "impossible to track, whose end cannot be traced," from the Greek a ("not") + ex ("out") + ichnos ("footprint, track"): "untrackable," like being in a forest and never finding the end of the trail. Christ's riches are not an inventory you can finish counting but a treasure you can never finish exploring.

"Unsearchable" appears only twice in the New Testament: here, and in Romans 11:33, "How unsearchable are his judgments, and his ways past tracing out!" Both are from Paul:

Taken together: what God "does" is unsearchable, and what Christ "has" is unsearchable, two sighs of wonder in Paul's letters.

3:9 "and to make all men see what is the administration of the mystery which for ages has been hidden in God, who created all things through Jesus Christ;"

Ephesians 3:9(World English Bible)

"To make all men see" (phōtisai pantas, "to illuminate everyone"). The verb phōtisai means "to light up, to enlighten" (the same root as phōs, "light"). Paul's mission is to "shine light," so that all may see this mystery. "All" stands in sharp contrast to the Greek mystery religions' "only for the initiated elite." The Christian "mystery" is completely open: no ticket, no secret entrance.

"Administration" (οἰκονομία, oikonomia) is the Greek word for "household management, administration" (the etymological root of economy). It refers to "God's method of executing his plan through history." The "mystery" is not merely a "truth" but an "unfolding plan," with stages, sequence, and timing (echoing 1:10, "to bring it to fulfillment in the fullness of the times," and Galatians 4:4, "when the fullness of the time came").

"Hidden in God, who created all things." The mystery was not thought up later; it is a plan that God "kept hidden in himself" from eternity, revealed to humanity only when "the time was full." This echoes Ephesians 1:4, "he chose us in him before the foundation of the world." The whole plan of salvation is rooted in the eternal God.

3:10 "to the intent that now through the assembly the manifold wisdom of God might be made known to the principalities and the powers in the heavenly places,"

Ephesians 3:10(World English Bible)

"That now through the church" (hina gnōristhē nyn tais archais kai tais exousiais en tois epouraniois dia tēs ekklēsias). "Through the church" (dia tēs ekklēsias) is the key phrase: the church is the "medium" through which God displays his wisdom to the heavenly "rulers and authorities."

"The principalities and the powers in the heavenly places" refers to spiritual beings (cf. 1:21, "far above all rule, authority, power, dominion," and 6:12, "against the principalities, against the powers, against the world's rulers of darkness, and against the spiritual forces of wickedness in the heavenly places"). This phrase can encompass both good angels (the angelic realm) and evil spiritual forces (Satan and his powers). Most interpreters lean toward "both," with angels and demons alike seeing God's wisdom in the church.

"Manifold wisdom" (ἡ πολυποίκιλος σοφία). Polypoikilos is an intensified compound of the Greek poly ("many") and poikilos ("varied, multi-colored"), literally "multi-colored, brilliantly variegated," like a richly woven tapestry or an artist's full palette. This word appears only here in the entire Bible (a hapax legomenon, "said only once").

What does "multi-colored" point to? It points to the "diversity within unity" that God displays through the church:

This "diversity in unity" is wisdom unique to God. Any human political system can achieve only "uniformity" (erasing diversity) or "plurality" (sacrificing unity); only God's wisdom achieves "the unity of the diverse."

"The church is the theater where angels observe God's wisdom" is one of the New Testament's most expansive ecclesiologies. Calvin called this theatrum gloriae Dei, "the theater of God's glory." Angels "stoop to look into" the church (1 Peter 1:12, "things which angels desire to look into"), learning about God from the church's very existence. They see how God turns enemies (Jew and Gentile, sinner and God) into brothers; they see how God turns the dead into new creatures. The church itself is "the physical exhibit of the gospel," a living lesson for angels, for the universe, for the world.

3:11-12 "according to the eternal purpose which he purposed in Christ Jesus our Lord; in whom we have boldness and access in confidence through our faith in him."

Ephesians 3:11-12(World English Bible)

"From eternity" (κατὰ πρόθεσιν τῶν αἰώνων, kata prothesin tōn aiōnōn, "according to the purpose of the ages"). The mystery is not God's contingency plan but part of his eternal design. The unity of Jew and Gentile is not a "backup option" after the Jews rejected the gospel; it is what God planned from the beginning. This mattered greatly to the early church. Some Jewish Christians (such as those in the Acts 15 debate) considered the Gentiles "secondary, temporary"; Paul firmly declares that the Gentiles' unity is what God planned from eternity.

"Boldness" (παρρησία, parrēsia), from the Greek pas ("all") + rhēsis ("speech"), "to say everything." In the ancient Athenian city-state, only free citizens had parrēsia (the right to speak publicly); slaves, resident aliens, and women had no such right. Paul "theologizes" this political term: now every believer has the right "to come before God in confidence," needing no intermediary, no priest, no sacrifice. This is the same theology as Hebrews 4:16 ("let us therefore draw near with boldness to the throne of grace") and Hebrews 10:19–22 ("having boldness to enter into the holy place by the blood of Jesus").

"In confidence" (ἐν πεποιθήσει, en pepoithēsei, "in trust"). The noun pepoithēsis comes from peithō ("to trust, to rely on"). It does not mean "I have no doubts" (cognitive certainty) but "I fully rely" (relational trust). Believers come before God not because "I am completely sure," but because "I fully rely on Christ."

3:13 "Therefore I ask that you may not lose heart at my troubles for you, which are your glory."

Ephesians 3:13(World English Bible)

Paul redefines his suffering: not as evidence that the apostolic work has failed, but as the believers' "badge of glory." He is in chains precisely because he was faithful to the mission of the Gentile gospel, so Gentile believers should not lose heart over it; rather they should take pride in it.

"Which are your glory" (ἥτις ἐστὶν δόξα ὑμῶν, hētis estin doxa hymōn). The word doxa means "glory." This is a reversed perspective. The world sees Paul's chains as "shame" (a criminal imprisoned by the Roman Empire); Paul sees his chains as "their glory" (the price paid for these Gentiles to become part of one body). This echoes Philippians 1:13–14: "my bonds became well known in Christ ... and most of the brothers in the Lord, being confident through my bonds, are more abundantly bold to speak the word of God without fear." Paul's suffering became, instead, a "shot in the arm" for the church's faith.

The pastoral meaning: when you endure injustice for Christ, your suffering is not "failure." It may be the very beginning of someone else's "glory." The price you pay for your faith will, in eternity, be counted as "their glory," because your perseverance bears witness to them that Christ is worth all of it.

③ 3:14-19 · The Second Prayer

Where this section stands: The prayer left unfinished at 3:1 is finally "picked up again" here; "For this cause" responds to the "For this cause" of 3:1. This is Paul's second prayer, opening with "bowing the knees," climaxing in "the four dimensions of love," and reaching its ultimate goal in "filled with the fullness of God," the deepest prayer in the New Testament. The structure of this section is a Trinitarian movement of "Spirit → Christ → God": asking the Spirit to strengthen the inner being → asking for Christ's indwelling → asking for the filling of God's fullness.

3:14-15 "For this cause, I bow my knees to the Father of our Lord Jesus Christ, from whom every family in heaven and on earth is named,"

Ephesians 3:14-15(World English Bible)

"For this cause" (Τούτου χάριν, toutou charin) is exactly the same as the "For this cause" of 3:1. Paul has finally "picked up" the prayer that 3:1 left unfinished. This grammatical "return" lets readers see the path of Paul's thought: from 3:1 he was reaching toward the prayer of 3:14, but along the way the grandeur of the "mystery" "interrupted" him; he had to finish telling of his mission before he could continue the prayer.

"Bow my knees before the Father" (kamptō ta gonata mou pros ton patera, literally "I bow my knees toward the Father"). Jews typically stood to pray (cf. Mark 11:25, "whenever you stand praying"; Luke 18:11, "the Pharisee stood and prayed to himself"). Paul's "kneeling" expresses the urgency of his prayer; one kneels only in the deepest prayer (as Solomon knelt when dedicating the temple, 1 Kings 8:54; Jesus knelt in Gethsemane, Luke 22:41; Stephen knelt at his martyrdom, Acts 7:60; Paul knelt when saying farewell to the Ephesian elders, Acts 20:36).

"Every family in heaven and on earth is named from him" (ἐξ οὗ πᾶσα, ex hou pasa). The words πατριά / πατήρ (patria / patēr), "family, clan" and "father," share the same root. Paul plays on this in Greek: "Father" (patēr) and "family" (patria) share one root, so the very word for "family" comes from "Father."

"The archetype of every 'family' comes from God, the 'heavenly Father.'" Human father-child relationships and family structures are not something God modeled on a human invention; rather, the human family reflects the heavenly archetype. This has profound pastoral significance:

"Every family in heaven and on earth." "Family" exists not only on earth but also in heaven! The angelic hosts also exist in the form of "families," consistent with the Jewish tradition that divides angels into different "ranks," "armies," and "families" (such as Michael as "chief" and Gabriel as "messenger"). So the family on earth and the angelic family in heaven both take their name from the same "Father."

3:16-17 "that he would grant you, according to the riches of his glory, that you may be strengthened with power through his Spirit in the inward man; that Christ may dwell in your hearts through faith; to the end that you, being rooted and grounded in love,"

Ephesians 3:16-17(World English Bible)

"According to the riches of his glory" (kata to ploutos tēs doxēs autou). The words ploutos ("riches") and doxa ("glory") matter, but note "according to" (kata) rather than "from." This preposition carries theological weight. "From" would mean "a portion drawn out of this source" (a millionaire gives you $100 out of his fortune); "according to" means "to a degree commensurate with this source" (a millionaire gives you a large check in keeping with his fortune). Paul asks God to give "according to" the measure of his glorious riches; however rich God is, that is the measure by which Paul asks God to give to the believers.

The first request of the prayer: the Spirit's inner strengthening, "strengthened with power through his Spirit in the inner person." "The inner person" (eis ton esō anthrōpon, "into the inner person") is not physical strength, intellect, or willpower, but "the inner self," the renewal of the soul's depths. Paul calls this "inner person" the part that "delights in God's law" (Romans 7:22); in 2 Corinthians 4:16 he says, "though our outer person is decaying, yet our inner person is being renewed day by day." This strengthening is not "self-improvement" but "the Spirit's work," the Spirit pouring Christ's resurrection power into the deepest part of your being.

The second request of the prayer: Christ's indwelling, "that Christ may dwell in your hearts through faith." The word "dwell" (κατοικῆσαι, katoikēsai, aorist active infinitive), from the Greek kata ("down") + oikeō ("to dwell"), means "to settle, to make a home," in contrast with paroikeō ("to sojourn, to live as a stranger").

The contrast of two "dwellings":

Paul uses the word for "permanent settlement" to describe Christ within the believer. Christ is not a passerby who drops in for an occasional visit, but the master who has moved in for good; he "moves into" your heart, sets down his luggage, and never leaves. This theology overturns the direction of "I go to find God." It is not that you travel to the temple to find God; rather, God moves the whole temple into you (cf. 2:22, "a dwelling place of God in the Spirit").

"Through faith." Christ's indwelling is realized "through faith." Faith is not "merit" but "the posture of receiving" (cf. John 1:12, "as many as received him, to them he gave the right to become God's children, to those who believe in his name").

"Being rooted and grounded in love" (en agapē errizōmenoi kai tethemeliōmenoi). Two passive perfect participles: errizōmenoi, "already rooted" (a plant metaphor, from rhiza, "root"), and tethemeliōmenoi, "already founded" (a building metaphor, from themelios, "foundation"). The dual metaphor of plant (root) and building (foundation) stresses love's depth and stability.

"Root": life sinking deep into the soil, drawing nourishment. "Foundation": a structure standing firm under heavy weight, withstanding wind and rain. Both stress that love is "foundational." Love is not an "add-on" but the "underground infrastructure" of the believer's whole life.

3:18-19 "may be strengthened to comprehend with all the saints what is the width and length and height and depth, and to know Christ’s love which surpasses knowledge, that you may be filled with all the fullness of God."

Ephesians 3:18-19(World English Bible)

The third request of the prayer: to comprehend the four dimensions of Christ's love, "to comprehend with all the saints what is the width and length and height and depth."

"Width, length, height, and depth" (to platos kai mēkos kai hypsos kai bathos). Paul uses four spatial dimensions to express the infinity of Christ's love. This is not a mathematical measurement; it uses the limits of space to express the limitlessness of love.

The interpretation history of "four-dimensional love":

Most modern scholars favor the "completeness" reading. Paul is not doing geometry; he is using every possible dimension to declare that Christ's love has "no blind spots." In no dimension can anything exceed Christ's love. You cannot say "Christ's love" stops at some point in any direction; in every direction it is endless.

Note "with all the saints" (σὺν πᾶσιν τοῖς ἁγίοις, syn pasin tois hagiois). Christ's love is too vast for one person to fathom; it can be grasped only as believers attest and witness it to one another within the community. No single believer can experience the full dimensions of Christ's love alone; you can experience only a part, and you need other believers to complete your experience. This directly echoes the "body" teaching of 1 Corinthians 12: different members of the body experience different dimensions of Christ's love, and only joined together can they present the whole.

Then comes a paradoxical request: "to know Christ's love which surpasses knowledge." Paul asks believers to "know" something they "cannot fully know." This is not a logical contradiction but a description of spiritual experience: you can come to know Christ's love more and more deeply while becoming ever more aware that this love always has deeper layers.

It is like standing at the seashore. You can feel the ocean's vastness, but you can never see its end; you can enjoy its immensity, but you can never pour the ocean into a bottle. Christ's love is the same: you can experience it but never exhaust it; you can enter it but never drain it. This is why Christian spirituality is a lifelong journey. In this life you will not reach the destination, but in this life you can move forward every day.

The ultimate goal of the prayer: "that you may be filled with all the fullness of God" (hina plērōthēte eis). Note plērōthēte, "be filled" (passive), and plērōma, "fullness" (noun), the same root repeated; in Greek it sounds like two overlapping bell strokes, "be filled ... into all the fullness."

"All the fullness of God" (pan to plērōma tou theou, "all the fullness of God") points to all of God's attributes, all of his riches, all of his resources, everything God "is." Paul asks that believers "be filled with all of this." This does not mean believers become God (that would be the extreme heresy of theosis, "humanity made divine"), but that believers are "filled to capacity" with God's fullness, like a container filled with water; the container is still a container, but what it holds is God's fullness.

This is the summit of Paul's prayer, not just "God, bless me," but "God, pour into me everything you are." If this prayer were not written by Paul under the Spirit's inspiration, it would be almost "blasphemous" in its boldness; but since it is a Spirit-inspired prayer, it is the prayer into which God invites every believer. You can pray it for yourself just as it stands, and God delights when you ask this way.

④ 3:20-21 · Doxology

Where this section stands: This is the grand doxology of the whole doctrinal section (chapters 1–3), answering the opening praise of 1:3–14 and forming a "praise → praise" inclusio. The whole prayer ends in doxology. Paul has just asked for "the four dimensions of love" and "filled with God's fullness," things already nearly impossible, and yet he has not said enough; in 3:20 he adds one more line: God is able to do even more than this.

3:20-21 "Now to him who is able to do exceedingly abundantly above all that we ask or think, according to the power that works in us, to him be the glory in the assembly and in Christ Jesus to all generations forever and ever. Amen."

Ephesians 3:20-21(World English Bible)

"God is able ... to do exceedingly abundantly all things" (τῷ δὲ δυναμένῳ). Note "dynamenō" ("is able"), "hyper panta" ("above all things"), "poiēsai" ("to do"), "hyperekperissou" ("super-out-of-abundantly"). Paul stacks up a cascade of "hyper-" (super-) intensifiers in Greek.

"Above all that we ask or think" (hyper panta ha aitoumetha ē nooumen). "Above" works on two levels:

  1. Above what we ask (what you can think to request)
  2. Above what we think (what you can imagine). Human limitation has two layers:

God breaks through both layers of limitation. He not only gives you "what you asked for"; he gives you "what you never thought to ask for," because his "manifold wisdom" (polypoikilos sophia, 3:10) always has a way you have not imagined.

"Hyperekperissou" is a "triple-intensified" adverb: hyper ("super") + ek ("out") + perissou ("abundantly"), literally "super-out-of-abundantly." Paul could not find one ordinary word to express "really, really, truly more," so he stacked three prefixes. This is Paul's description of God's power: "super-out-of-abundantly," more than you can describe.

"According to the power that works in us" (kata tēn dynamin tēn energoumenēn en hēmin). The words dynamis ("power") and energoumenēn ("working," the root of energy) show that this power is not "external" (God is not "reaching down" from heaven to act) but "internally working" (already operating inside the believer). This is the same power as 3:16, "strengthened in the inner being through his Spirit." The Spirit is already "switched on" inside every believer, waiting to work.

"In the church and in Christ Jesus" (en tē ekklēsia kai en Christō Iēsou). The place where God receives glory is not only heaven, not only the temple, but "the church" and "Christ Jesus," the two named side by side.

This is a stunning juxtaposition. "The church" stands beside "Christ Jesus" as the place where "God receives glory," meaning that the church, in some sense, shares with Christ the function of "displaying God's glory." This elevates ecclesiology to a cosmic level: the ultimate meaning of the church's existence is that God receives eternal glory in it. The church is not just "a place where believers gather"; it is "the theater of God's glory."

"To all generations, forever and ever" (εἰς πάσας τὰς, "unto all the generations of the age of the ages"). Paul piles up "generations" upon "generations" upon "generations" in Greek, a triple-layered emphasis on "absolutely forever." The church's glory-giving will not cease until the end of all the ages.

"Amen" (ἀμήν, amēn) is Hebrew for "truly, so be it," the seal of a confession of faith. Paul's doxology ends with this seal, inviting the reader to say "Amen" together, completing a "collective declaration" to God.

Theological Points of the Chapter

1. Overview of Core Theological Points

Theme Content
Doctrine of the Mystery The mystery is not something unknowable but a plan of God previously hidden and now revealed; its core content is the complete, equal unity of Jew and Gentile in Christ; Paul's reverse usage of Greek mystery-religion terminology: the Christian mystery is completely open
Doctrine of Apostleship Paul's apostleship rests on direct revelation (3:3), not a human commission; his suffering is the mark of his mission, not evidence of failure; calling himself "less than the least" displays the spiritual law that "the greater the grace, the smaller the self"
The Cosmic Significance of the Church The church serves not only earthly people but is the platform that displays God's wisdom to the spiritual realm (3:10): theatrum gloriae Dei ("the theater of God's glory"); the meaning of the church's existence transcends its earthly function
Doctrine of Christ's Indwelling Permanent settlement versus temporary sojourn: Christ moves into the believer's heart, sets down his luggage, and never leaves; this dwelling is "through faith," not "through works"
The Transcendence of Christ's Love "Width, length, height, and depth" (four-dimensional love) plus "surpassing knowledge": it can be known ever more deeply yet never exhausted; this tension of "known and unknown" is the normal state of spiritual life: a lifelong journey
Communal Spirituality "With all the saints" (3:18): Christ's love is too vast for one person to fathom alone; only by mutual witness within the church community can its full dimensions be grasped: this is a fundamental rejection of "individualistic spirituality"
The Transcendence of God He can do "above all that we ask or think": God is not limited by human imagination; yet his work is "according to the power that works in us," operating internally within the believer's life (not reaching in from outside)
The Goal of "Filling" "That you may be filled with all the fullness of God": the believer is filled to capacity with God's fullness, the container filled with the source; not the heresy of "humanity made divine" but believers becoming containers of God's glory and love

Diagram of the Argument's Structure

1. Literary Structure Analysis

Chapter 3 displays a finely crafted "interruption and recovery" structure:

A   Paul begins the prayer (3:1)
    "For this cause, I, Paul..." — the sentence breaks off

    B   Mission self-description (inserted section, 3:2-13)
        B1  The mystery's content (3:2-6): three syn- compounds
        B2  The mission's execution (3:7-12): proclaiming the unsearchable
            riches, the church displaying wisdom to the angels
        B3  The mission's cost (3:13): suffering is glory

A'  Paul resumes the prayer (3:14-21)
    "For this cause, I... bow my knees" — picking up 3:1
    A1  The prayer's posture (3:14-15): kneeling before the Father
    A2  Request 1: strength in the spirit, Christ dwelling within (3:16-17)
    A3  Request 2: comprehending Christ's love, filled with God (3:18-19)
    A4  Doxology: above all that we ask or think (3:20-21)

This structure reveals Paul's writing habit: his thought is like a tree; the trunk (prayer) grows a branch (the mission self-description), and the branch returns to the trunk. The reader needs patience to follow this "thought-walk," because each "detour" adds depth to the main line.

A and A' correspond exactly in their "For this cause." Paul uses the same connective to weld the two separated prayer segments together, a classic inclusio technique in Greek rhetoric (the praise of 1:3–14 and the doxology of 3:20–21 are likewise an inclusio framing the section).

The "insertion" of section B is not a loss of control but a deliberate rhetorical strategy. Paul wants readers to know the pray-er before they hear the prayer, to understand what qualifies him to intercede. This parallels the Jewish prayer tradition of "announcing one's identity first" (a priest introduced himself before offering sacrifice).

Tracking Theological Themes

The Progressive Unfolding of the Doctrine of the Mystery (Six Stages in Ephesians)

The progressive disclosure of "mystery" in Ephesians:

Place Stage Content
1:9-10 Ultimate goal In the fullness of the times, to unite all things in heaven and on earth in Christ (ἀνακεφαλαιώσασθαι (anakephalaiōsasthai): "to sum up under one head")
3:3-6 Concrete content Gentiles and Jews fellow heirs, fellow members of the body, fellow partakers of the promise (three syn-)
3:10 Cosmic function Through the church, displaying God's manifold wisdom to the spiritual realm
5:32 Marriage analogy The relationship of Christ and the church is the archetype of human marriage
6:19 The proclamation mission Paul asks for intercession that he may boldly make known this mystery

The whole thread shows that "mystery" is not an isolated doctrine but the narrative spine of Ephesians, from the eternal plan (ch. 1) to its historical realization (chs. 2–3) to its application in life (chs. 4–6).

The Two Prayers Compared (the New Testament's most beautiful "double prayer" structure)

Ephesians 1–3 uses two prayers as twin pillars supporting the whole doctrinal section:

Dimension First Prayer (1:15-23) Second Prayer (3:14-21)
Object "the God of our Lord Jesus Christ" "bowing the knees before the Father"
Posture (unstated) kneeling: expressing urgency
Core Request the spirit of wisdom and revelationknowing God strength in the inner beingexperiencing Christ's love
Direction from God's power to the church's standing from the Spirit's indwelling to the fullness of God
Trinitarian Structure Father → Son → Spirit Spirit → Son → Father
Climax Christ seated in heaven, the church his body (1:22-23) God able to do above all we ask or think (3:20-21)
Emphasis knowing (the power and plan to know God) experiencing (being personally filled with Christ's love)

The two prayers are complementary: the first emphasizes "knowing," the second "experiencing." The complete life of faith needs both joined together. "Knowing" without "experiencing" is dry doctrine; "experiencing" without "knowing" is a spirituality without foundation. Paul's prayer teaches us to run on "both tracks together," understanding with the heart and knowing by experience.

The Cosmic Significance of the Church (theatrum gloriae Dei)

In his Institutes of the Christian Religion, Calvin draws on 3:10 ("through the church the principalities and the powers might now know the manifold wisdom of God") to argue that "the church is the theater of God's glory" (theatrum gloriae Dei):

The subversive force of this ecclesiology:

Historical Background

"Mystery" in the Greek Mystery Religions and Paul's Reverse Usage

The word "mystery" was tightly bound to secret rites in the Gentile cultures:

Mystery Cult Center Content
The Eleusinian Mysteries Eleusis, near Athens Secrets concerning Demeter (goddess of the harvest) and Persephone: only the initiated could take part
The Cult of Mithras Persian in origin, spread widely by the Roman legions Secrets concerning the light-god Mithras: seven grades of initiation, the higher the more secret
The Dionysian Mysteries The Greek city-states Ecstatic rites concerning Dionysus (the god of wine)

The shared features of these mysteries:

Paul's "reverse usage" of the word "mystery":

The precise definition of "mystery" in the New Testament is "God's previously hidden plan, now disclosed." It keeps the connotation of "hiddenness" yet completely inverts the elitist exclusiveness of the Greek mystery religions. This "word borrowing" was a typical strategy of early Christianity in its dialogue with Greek culture: using a vocabulary familiar within the cultural context while filling it with entirely new content.

Paul's Imprisonment and custodia militaris

When Paul wrote Ephesians, he was probably under house arrest in Rome (Acts 28:16, 28:30, "Paul stayed two whole years in his own rented house"). The Roman custodia militaris ("military custody") was a form of house arrest:

The pastoral significance of this background:

The Interpretation History of the "Four-Dimensional Love" (Width, Length, Height, Depth)

Paul uses "width, length, height, and depth" (πλάτος / μῆκος / ὕψος / βάθος (platos / mēkos / hypsos / bathos)) to describe the full dimensions of Christ's love, and this expression has generated a rich interpretive tradition among the church fathers and later theologians:

Interpreter Era Reading
Origen 3rd century The four directions of the cross: the length of the horizontal arms, the height and depth of the vertical beam: the cross itself is the physical display of "four-dimensional love"
Augustine (Augustine) 4th–5th century The completeness of love: length = endurance / width = universality / height = transcendence / depth = penetration
Aquinas 13th century Four attributes of Christ's love: length = eternity / width = universality / height = supremacy / depth = the depth of redemption
Wesley 18th century Love for all people: length = from everlasting to everlasting / width = every person without exception / height = reaching all the way to heaven / depth = touching the most fallen sinner: one of the biblical bases for Wesley's Arminian "universal redemption" position
F. F. Bruce (Bruce) 20th century Rhetorical intensification: Paul is not doing geometry but using "every possible direction" to stress "all-encompassing"

Most modern scholars favor the "rhetorical intensification" view: Paul uses the limits of space simply to express "complete infinity," without needing a specific meaning for each direction; the point is "no dimension can exceed Christ's love." This reading better honors Paul's literary rhetoric and avoids over-allegorizing.

A Comparison of the Two New Testament Occurrences of "Unsearchable Riches"

Place Text Content
Romans 11:33 "How unsearchable are his judgments, and his ways past tracing out!" God's "judgments and ways" are unsearchable
Ephesians 3:8 "the unsearchable riches of Christ" Christ's "riches" are unsearchable

Both are from Paul. The former comes after the discussion of the mystery of "Israel and the Gentiles" in Romans 9–11 (Romans 11:33–36 is the climactic doxology); the latter comes after "the revelation of the mystery" in Ephesians 3. Both are "sighs of praise": after explaining God's great work, Paul cannot help but stop and marvel. This pattern of "first explain, then sigh in wonder" is a typical rhythm in Paul's letters.

The Six Occurrences of "Mystery" in Ephesians

Ephesians is the book with the highest density of the word "mystery" in the New Testament, six times, the densest among Paul's letters:

The six occurrences form a full-orbed unfolding of "mystery": from origin (1:9, the mystery in God's will) → revelation (3:3–9, given to the apostles by revelation) → application (5:32, marriage as its analogy) → proclamation (6:19, asking intercession to make it boldly known).
