Descubriéndonos|strong="G1107, G2254" el misterio de su voluntad, según su beneplácito, que se había propuesto en sí mismo,
E nos revelou o mistério da sua vontade, conforme o seu bom prazer, que propôs nele,
nous faisant connaître le mystère de sa volonté, selon le bienveillant dessein qu’ il avait formé en lui-même,
und er hat uns wissen lassen das Geheimnis seines Willens nach seinem Wohlgefallen, so er sich vorgesetzt hatte in ihm,
Ons bekend gemaakt hebbende de verborgenheid van Zijn wil, naar Zijn welbehagen, hetwelk Hij voorgenomen had in Zichzelven.
col farci conoscere il mistero della sua volontà, giusta il disegno benevolo ch’Egli aveva già prima in se stesso formato,
Oznajmiwszy nam tajemnicę woli swojej według upodobania swego, które był postanowił w samym sobie;
открыв нам тайну Своей воли по Своему благоволению, которое Он прежде положил в Нем,
都是照 他自己 所預定的 美意，叫我們 知道 他 旨意 的奧祕，
Having made clear to us the secret of his purpose, in agreement with the design which he had in mind, to put into his hands

Scholars' Consensus
Commentators across traditions agree on the central thrust: God has disclosed a secret long hidden. The word "mystery" (μυστήριον, mustērion) does not mean something unintelligible but a truth previously concealed, now openly declared. Barnes and Clarke focus on the specific content, the inclusion of Gentiles into the people of God without the Mosaic law, a truth that scandalized many early believers. Calvin and Gill emphasize the broader canvas: the whole redemptive plan springing from God's sovereign good pleasure. The Cambridge Bible notes that the aorist participle γνωρίσας ("having made known") points to the historic moment of the gospel's proclamation. All agree that the revelation is wholly gratuitous: it flows from God's own εὐδοκία (eudokia), his benevolent delight, not from human worth. A minor debate persists over the phrase "in him" (ἐν αὐτῷ): some read it as "in himself" (the Father), others as "in Christ." But the main point stands: the mystery is God's will, now revealed, and it culminates in Christ. This means believers stand on ground that is not dark but disclosed, not a riddle but a gift.
How settled is the interpretation?
Interpretive difficulty: Medium
Main views:
- Inclusion of Gentiles: Clarke and Barnes argue from the context of Jewish-Gentile tension in the early church (Eph 2:11-22; 3:6) and the immediate contrast with the Old Testament concealment of this specific plan.
- Cosmic reconciliation in Christ: Calvin, Gill, and Cambridge point to verse 10 and the summing up of all things in Christ, seeing the mystery as the entire redemptive plan including cosmic renewal.
What is clear: God has revealed a once-hidden plan of salvation according to his own good pleasure, and this revelation is centered in Christ and made known to believers.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Nature of the mystery | It is a truth hidden in past ages, now revealed by God through the gospel. | Some see it as the inclusion of the Gentiles (Clarke, Barnes); others as the entire redemptive plan centered on Christ's cosmic headship (Calvin, Gill, Cambridge). |
| Meaning of 'purposed in him' | All affirm that God purposed his plan from eternity. | Some commentators read 'in himself' (God the Father) based on grammar (Vincent, JFB); others read 'in Christ' based on the immediate context (Eph 1:10, Cambridge). |
| Basis for revelation | The revelation flows from God's own good pleasure (eudokia), not human merit. | Tensions remain between those who emphasize human response and those who stress unconditional divine decree, but all agree the initiative is God's. |
Historical & Cultural Context
Ephesus was a city steeped in magical practices and the cult of Artemis (Acts 19). Paul's audience included both Jewish believers and former pagans, each bringing deep assumptions about access to God. Into this setting Paul proclaims a "mystery", a term his Greco-Roman readers would associate with secret knowledge for the initiated. But Paul redefines it completely. The biblical mystery is not a secret for an elite; it is a plan God kept in his own counsel and has now broadcast openly. The surrounding context (Eph 1:3-14) is a single sweeping sentence of praise, tracing the believer's blessings from the Father's eternal choice (v.4) through the Son's redemption (v.7) to the Spirit's sealing (v.13). Verse 9 sits at the hinge: the revelation of the mystery is what Paul calls "making known to us" what was previously hidden. Early Jewish Christians struggled to accept that Gentiles shared equally in God's promises (Acts 10-11). Paul insists that this inclusion was not an afterthought but God's purpose from the beginning, "according to his good pleasure." The phrase "good pleasure" (εὐδοκία) signals God's free delight, not a grudging concession. For believers in a divided city, this was news that rewired their identity: they were not insiders by birth but by revelation. And the revelation itself was an act of grace, not a reward for insight.
Textual Notes
The Greek pronoun αυτῷ can be read as "himself" (the Father) or "him" (Christ). Most modern critical editions (NA27, UBS4) read αυτῷ, leaving the referent ambiguous. The KJV and most older translations read "himself," while the BSB and WEB read "him" (likely referring to God, but ambiguous). There are no other significant variants in this verse.
Reception History
Since the early church, Ephesians 1:9 has been read as a key text on divine revelation and predestination. In the Eastern tradition, the mystery was often linked to God's plan for the world's deification in Christ. Augustine and later Reformed theologians used the verse to argue for God's sovereign free choice in salvation. The Wesleyan tradition emphasized the revealed nature of the mystery, accessible to all believers. In modern biblical scholarship, the "mystery" is often identified with the Christ-event itself, God's plan to unite all things in Christ. The verse also appears in liturgical contexts, especially in hymns that celebrate the hidden wisdom of God now made known. Across these traditions, the consistent note is that God has not left humanity in ignorance but has graciously disclosed his purposes in Christ.
Preaching This Verse
Three-point outline
- The Hidden Secret: The "mystery of his will" was not a puzzle but a purpose kept hidden until the appointed time.
- The Open Announcement: God "made known" this secret to believers through the gospel and the Spirit, removing the veil.
- The Source: Good Pleasure: The revelation flows from God's own delight, not from any human merit or initiative.
Five-point outline
- A Plan Concealed: The mystery existed in God's mind before creation (cf. Eph 1:4).
- A Plan Disclosed: In Christ's coming and the apostolic preaching, the mystery was made known to us.
- A Plan Centered on Christ: The purpose was "purposed in him", Christ is both the agent and the content of the plan.
- A Plan from God's Free Choice: "According to his good pleasure" underlines that God's will is self-motivated and gracious.
- A Plan for Our Praise: The ultimate goal is "to the praise of his glory" (v.12, 14), drawing worship from the redeemed.
Illustration hooks
- A sealed letter: Imagine receiving a letter that you cannot open until a certain date. The day arrives, and you finally read the writer's intentions. God's mystery was sealed until Christ, and now the contents are open for all who believe.
- A surgical diagnosis: A doctor may know a condition but withholds the full explanation until the patient can bear it. God revealed the mystery of his will at the right time, when the world was ready through Christ.
- An inheritance announcement: A parent plans an inheritance but keeps the details quiet until the child is mature. God's good pleasure was always there, but he revealed it when the "fullness of times" came (Eph 1:10).
Questions your congregation is asking
- If the mystery is now revealed, why does life still feel confusing? The revealed mystery is about God's overall plan of salvation, not every detail of our personal circumstances. We walk by faith in the big picture he has disclosed.
- Does "mystery" mean we cannot understand God's will at all? No. In the Bible, a mystery is what is hidden until God reveals it. Once revealed, it can be known and trusted, though it remains beyond full human comprehension.
- How does this verse help me when I doubt God's purpose for my life? It reminds you that God's plan is not arbitrary but flows from his good pleasure, his delighted intention toward you in Christ. Your place in that plan is grounded in his free choice, not your performance.
Leading a Discussion
This verse draws us into the center of Paul's praise. God could have remained silent; instead, he made known the mystery of his will. Use these questions to guide a group discussion that moves from noticing the details to applying the truth.
Discussion questions
- Observation: List all the verbs in Ephesians 1:9 (e.g., "making known," "purposed"). Who is the subject of each action?
- Observation: What does the word "mystery" bring to mind? How does Paul define it (the mystery of his will, of his good pleasure)?
- Interpretation: In the New Testament, "mystery" often refers to a truth once hidden but now revealed (see Rom 16:25-26, Col 1:26-27). How does that reshape the way you read this verse?
- Interpretation: Paul says the revelation is "according to his good pleasure." Why is that phrase important? What does it say about God's motivation?
- Interpretation: The phrase "purposed in him" (or "in himself") is debated. How does the immediate context (Eph 1:10) help you decide the reference to Christ? What difference does it make?
- Application: If the mystery of God's will is now made known to us, what are we expected to do with this knowledge? How does it affect our worship, our witness, and our daily choices?
- Application: Think of an area in your life where God's plan feels unclear. How does the assurance that he has revealed the ultimate mystery (salvation in Christ) give you patience and trust for the smaller unknowns?

What the Commentators Say
8 public-domain commentaries, condensed into plain language.
Adam Clarke's Commentary Methodist/Wesleyan 1826
Clarke emphasizes that the inclusion of Gentiles in God's church, without requiring them to follow Jewish law, had never been revealed until this time. He calls it a hidden mystery, now disclosed to the apostles, and describes God's "good pleasure" as a self-originating, benevolent purpose not prompted by anything outside himself.
Barnes' Notes on the Bible Protestant 1832
Barnes insists that "mystery" in the New Testament never means something above human comprehension. Instead it describes a truth that was previously concealed through figures and symbols but once revealed, becomes as clear and plain as any other doctrine.
Calvin's Commentaries Reformed 1564
Calvin insists that the gospel reaching the Gentiles is not an innovation or accident. It was always God's hidden purpose, kept secret in His own will until the moment He chose to reveal it. No one has grounds to object, because God alone knows and decides when to disclose His mysteries.
Cambridge Bible for Schools and Colleges Anglican 1880
The commentator clarifies that in Scripture, a mystery is not something puzzling or confusing but a truth that can only be known through divine revelation. They also note that God's purpose was made in Christ, not in isolation, as it takes effect through the Son and the Church united to Him.
Geneva Bible Notes Reformed 1599
And hath opened vnto vs the mysterie of his will according to his good pleasure, which he had purposed in him,
Gill's Exposition of the Bible Baptist 1748
Gill identifies the "mystery of God's will" as the Gospel, which reveals God's sovereign plan in saving sinners. This mystery is made known through the Spirit and the Word, but only to those and at times God has purposed in Himself according to His good pleasure. The entire work of salvation is according to God's sovereign will and choice.
Vincent's Word Studies Evangelical 1887
Vincent stresses that the mystery of God's will is His grace in redemption, belonging to His eternal plan, and can be known only through divine revelation. He clarifies that the textual reading "in Him" refers to God, not to Christ, who appears separately in the next verse.
Wesley's Explanatory Notes Methodist/Wesleyan 1754
Wesley emphasizes that the mystery of God's will in salvation is fully revealed only through Scripture and the Spirit. Hidden from unbelievers and only dimly foreshadowed under the law, this gracious plan still exceeds everything even true believers can fully grasp.
