Christ: The Wonder of It All
A theological meditation on 2 Thessalonians 1:10
There is a kind of glory that can be discussed, defended, even defined—yet still not truly seen. Scripture does not leave the hope of believers as an abstract doctrine, but presses it toward a final horizon: the Day when Christ is no longer merely confessed by faith, nor only known by the present experience of spiritual life in a mortal body, but entered as the wonder of immortality—the consummation of eternal life, which God purposed before time and has already set within our hearts, beheld in unveiled reality. Paul gathers this horizon into a single sentence that feels like it is too much to imagine:
“...when He comes on that day to be glorified in His saints, and to be marveled at among all who have believed...” — 2 Thessalonians 1:10
But let out limited minds pray for a spirit of wisdom and revelation into this wonder. The promise is not only that Christ will be glorified, but that His glory will be displayed in His people—and that the appropriate human response will be wonder: not curiosity, not analysis, but astonished worship. Christ Himself will be “the wonder of it all.”
The grammar of glory and wonder
Two verbs in 2 Thessalonians 1:10 open the theological center of the passage.
First: “to be glorified.” Paul uses ἐνδοξασθῆναι (endoxasthēnai), “to be glorified” or “to be made glorious,” with the sense of being publicly displayed in honor—glory not merely possessed, but manifested. Christ’s glory is intrinsic and eternal, yet on “that day” it will be seen in a new way: as His saving work is exhibited in a people who have been fully conformed to Him.
Second: “to be wondered at.” Paul uses θαυμασθῆναι (thaumasthēnai), “to be wondered at / marveled at.” The word is not a cool admiration; it is the language of astonishment, the kind that silences boasting because it is confronted with something greater than the mind can hold. On that Day, Christ will not merely receive praise because praise is appropriate—He will draw praise because He will be seen as He is, and His people will finally recognize, without distortion, what He has accomplished.
This is already implied in the structure: He comes “to be glorified in His saints” and “to be marveled at among all who have believed.” Wonder is not a side effect; it is the fitting response when glory and redemption (a glorified body) is unveiled and the meaning is no longer debated but revealed. It is to the praise of his glory that there exists a people like him, see The Promises of God —To The Praise of His Glory.
“Glorified in the saints” is not flattery—it is transformation
“Glorified in His saints” does not mean Christ becomes more glorious in Himself, as though He lacked anything less glorious. It means His glory is displayed through what He has made of His people. The glory of the Redeemer is seen in the redeemed.
This coheres with Paul’s wider teaching that salvation is not only forgiveness but a new creation. Romans describes the saving purpose of God as conformity to Christ: “those whom He foreknew He also predestined to be conformed to the image of His Son” (Romans 8:29), and it culminates in glorification (Romans 8:30).
The same logic appears in Colossians: “When Christ who is your life appears, then you also will appear with Him in glory” (Colossians 3:4). Christ is not only the object of future glory; He is the source and pattern of it, the One in whom glory becomes communicable to His people without becoming idolatry.
This is why the Day of the Lord is described as a Day of revelation. What is now hidden—what believers are “in Christ”—will become visible. The saints will not merely visit glory, they will be like him in glory, the arena in which the glory of Christ and his brethren are recognized as triumphant.
From glory to glory: the present work that anticipates the final unveiling
Paul does not reserve transformation for the end only. He insists that the Spirit is already working a glory-shaped change in believers now:
“And we all, with unveiled face, beholding the glory of the Lord, are being transformed into the same image from glory to glory...” — 2 Corinthians 3:18
The phrase “from glory to glory” locates the Christian life as a movement of increasing participation in the likeness of Christ. The transformation is real, yet partial—true, yet not final. It is the seed, an imperishable one, of the harvest, the Spirit a down payment of the inheritance, until God takes redemption of his own. We are saved, being saved, and will be saved in spirit, soul, and body.
Then Paul sharpens the object of this beholding: it is not a vague spirituality, but the glory of God revealed in the face of Jesus Christ.
“For God, who said, ‘Let light shine out of darkness,’ has shone in our hearts to give the light of the knowledge of the glory of God in the face of Jesus Christ.” — 2 Corinthians 4:6
Here the “face of Jesus Christ” is not merely metaphor. It is the claim that God’s glory is now known personally, not only propositionally. The glory that once shattered mountains now shines through a crucified and risen Person. And because that glory is mediated through Christ, it does not destroy believers—it transforms them.
So 2 Thessalonians 1:10 becomes the consummation of a present process. What believers behold by faith now will be beheld by sight then; what is changing them in measure now will finalize them in fullness then. The same Christ—His same glory—will move from “known” to “seen,” from “tasted” to “consummated.” From knowing in part, to being fully known, who we are in Christ.
Distinct glories, one destiny: the resurrection body and the glory of the heavenly Man
We can connect this wonder to Paul’s teaching in 1 Corinthians 15:40–49, where Paul speaks of different kinds of glory and then applies that pattern to the resurrection.
He observes that there are “heavenly bodies and earthly bodies,” and that even among the heavenly lights there is distinction—sun, moon, stars—each with its own glory (1 Corinthians 15:40–41). The glory of God's creation. Then he turns the analogy into promise: “So is it with the resurrection of the dead” (1 Corinthians 15:42). The body that is sown perishable is raised imperishable; sown in dishonor, raised in glory; sown in weakness, raised in power; sown a natural body, raised a spiritual body (1 Corinthians 15:42–44).
There is the glory of creation, the earth and the heavens, and there is the glory of being a new creation in Christ.
The resurrection is not a return to what was lost, but an advance into what was promised, something new. Not merely repaired mortality; it is transformed humanity—humanity finally fitted for the unveiled presence of God, not by becoming less human without individual will, but by being made fully alive in the life of the risen Christ.
Paul’s climax in that section is identity: believers will bear the likeness of the heavenly Man. The contrast is Adam and Christ, the first man and the last Adam, the man of dust and the man of heaven (1 Corinthians 15:45–49). Whatever mysteries remain about how this will appear in detail, Paul’s certainty is firm: the resurrection will be Christ-shaped. Glory is not generic; it has a face. It has a pattern in the Son of Man and the Son of God.
That is why wonder belongs to the promise. When believers finally bear the likeness of Christ in a glorified body, they will not congratulate themselves—they will marvel at Him. All the crowns of reward will be incomparable to such glory, thus will be thrown at his feet, The transformation will be so complete, and so obviously His work, that it will produce the astonishment described by θαυμασθῆναι (thaumasthēnai).
Face to face: fullness replacing partial sight
The language of “wonder” is inseparable from the language of “fullness.” Paul describes the present life of faith as truly knowing, yet knowing in part:
“For now we see in a mirror dimly, but then face to face. Now I know in part; then I shall know fully, even as I have been fully known.” — 1 Corinthians 13:12
The “face to face” promise is not merely improved information; it is direct communion, unmediated clarity, the end of distortion. It is glorification (Romans 8:13-30). The partial will be put away, not because it was false, but because it was incomplete. What faith apprehended as a promise from a far, face to face will apprehend it fully. What the heart believed, the eyes will behold. And the astonishing thing is that this fullness is not impersonal: it is relational—being “fully known” and “knowing fully” in the presence of Christ.
This is why the Day described in 2 Thessalonians 1:10 is so bright: it is the convergence of glorification and recognition. Christ will be glorified in His saints, and His saints will finally recognize what that glory truly is—Christ Himself shining through what He has made them to be.
"And those he foreknew he also predestined to be conformed to the image of His son, so he exists the first fruit of many brethren. Now, those he predestined, he called, and those he called, he justified, and those justifies, he glorifies," (Romans 8:29-30).
From a corrupt body, to a glorified body, from a moaning that awaits a salvation that reveals the children of God as to who and what they are, to a creation set free from its bondage to decay, into its glorious freedom as the children of God (Romans 8:13-30).
“We will be like Him”: the simplest sentence, the deepest wonder
John’s words are almost startling in their simplicity:
“Beloved, we are God’s children now, and what we will be has not yet appeared; but we know that when He appears we shall be like Him, because we shall see Him as He is.” — 1 John 3:2
John does not resolve every curiosity about the future state. He gives one causal chain: seeing Christ “as He is” results in being “like Him.” The vision is transformative. The sight is sanctifying to completion. And the likeness is not autonomy; it is participation—humanity finally aligned with the true human, Jesus Christ.
Paul states the same destiny in different words: Christ “will transform our lowly body to be like His glorious body” (Philippians 3:21). Again, the center is Christ. The body is “like His.” The glory is “His.” The transformation is “His” act. The end is not merely survival after death; it is likeness to the risen Lord.
When those promises land on 2 Thessalonians 1:10, the logic becomes doxological: if we will be like Him in glory, and if this likeness exists to display His triumph, then the most natural response is wonder. We will not stand before Him as detached observers of glory. We will be living testimonies of it—His glory manifested in His saints—leading to the shared astonishment of all who believed.
The wonder of it all: Christ as both the sight and the splendor
The final consummation is not simply that heaven is beautiful or that eternity is endless. The consummation is that God’s fullness is enacted in Christ, and believers are brought into that fullness by union with Him. Glory is not an abstract light; it is the radiance of God revealed “in the face of Jesus Christ” (2 Corinthians 4:6). And believers are not merely invited to look—they are transformed as they behold (2 Corinthians 3:18), until the Day comes when Christ is “glorified in His saints” and “marveled at among all who have believed” (2 Thessalonians 1:10).
Christ, the wonder of it all.
