The theological concept of theōsis (θέωσις) describes the scriptural truth that believers are called to become partakers of the divine nature, to be conformed to the image of Christ, and to be transformed from glory to glory until we are fully made like Him. This is not becoming God — it is the deepest form of healing: becoming by grace what Christ is by nature.

"you may become partakers of the divine nature, having escaped from the corruption that is in the world because of sinful desire." (2 Peter 1:4)
Sharing What Belongs to Another · koinōnos · G2844 · GREEK
Partner, sharer, participant — one who holds something in common with another. Peter says we are invited to share in what belongs to God Himself: His own nature.
Peter does not say we will observe the divine nature or appreciate it from a distance. He says we will become partakers — koinōnoi — of it. The word implies genuine participation in something that genuinely belongs to another. God is not offering us a closer look at who He is — He is offering us a share in it, a participation in divine life through union with Christ. This is not deification in the sense of becoming a separate deity; it is adoption, union, and transformation so complete that we begin to carry, however partially, the character of the One we have been united with.
📖 2 Peter 1:3–11 · Everything We Need, Given for This PurposePeter introduces theosis as the destination of a process that God has already fully resourced. "His divine power has given us everything we need for a godly life through our knowledge of him who called us by his own glory and goodness." Everything needed. Already given. Not to be earned or requested — to be received and applied.
The goal of this provision is stunning: "so that through them you may participate in the divine nature." Peter is saying that the reason God has given you everything you need is not so that you can be a better person by human standards. It is so that you can become a partaker of what God is.
He then describes what this looks like in practice: faith, goodness, knowledge, self-control, perseverance, godliness, mutual affection, love — each one building on the last, each one a step in the direction of becoming the kind of being who reflects the character of the Creator.
Theosis is not passive. It is the most active thing a human being can do: cooperating with divine grace in the transformation of a fallen creature into someone who, by grace, looks more and more like God.
"For those God foreknew he also predestined to be conformed to the image of his Son." (Romans 8:29)
Shaped Into the Same Form · symmorphos · G4833 · GREEK
Conformed, sharing the same form — not merely similar in some respects but shaped according to the same pattern, bearing the same defining characteristics.
The goal God set for your life before time began was not that you would be successful, comfortable, or impressive by human standards — it was that you would be conformed to the image of His Son. Every experience God allows in your life — every joy and every suffering — is in service of this singular, eternal goal: making you look more like Jesus. This is theosis as predestined purpose: God has decided in advance that the destination of every believer is Christlikeness, and He is willing to use everything in your story to get you there.
📖 Romans 8:28–30 · The Golden Chain from Foreknowledge to GloryPaul links five unbreakable realities in Romans 8:29–30: foreknew, predestined, called, justified, glorified. Theologians call it the "golden chain." What matters for theosis is the middle link: predestined to be conformed to the image of his Son.
This is not one of God's goals for believers. It is the goal — the single stated purpose of predestination. God didn't choose you so that you could attend a good church or have a moral life or feel spiritually comfortable. He chose you so that you would become, over the course of your entire existence, a person who looks more and more like Jesus.
Every link in the chain serves that purpose. Being called is how you enter the process. Being justified is how you are cleared to begin. Being glorified is the completed version of what being conformed to Christ's image was building toward all along.
You are in the middle of a process that began before your birth and ends in a glory not yet revealed. Theosis is the name for what is happening to you right now.
"And we all, with unveiled face, beholding the glory of the Lord, are being transformed into the same image from one degree of glory to another." (2 Corinthians 3:18)
Change at the Root · metamorphoō · G3339 · GREEK
To be transformed, transfigured — a change so fundamental it reaches the core of what something is. The same word used for Jesus' transfiguration on the mountain.
The word Paul uses for transformation — metamorphoō — is the same word used when Jesus was transfigured on the mountain, when His inner glory became visible on the outside. That is what is happening to every believer who keeps their face turned toward the Lord with nothing between them and His glory. Theosis is not an achievement — it is an exposure. You don't earn transformation; you receive it by maintaining an unveiled, turned face toward Christ. And the process never finishes in this life — it moves from one degree of glory to another, always increasing, always becoming more.
📖 Matthew 17:1–2 · The Mountain Where Inside Became OutsidePeter, James, and John climbed a mountain with Jesus and watched Him change. Not metaphorically — physically. "His face shone like the sun, and his clothes became as white as the light." What had always been true on the inside was suddenly visible on the outside. The divine nature that had been veiled in flesh was, for a moment, unveiled.
Paul says that what happened to Jesus on that mountain is happening to us — not all at once, not as dramatically, but really and progressively. The glory that was already in us — placed there by the indwelling Spirit — is being expressed more and more in our character, our choices, and our lives.
"From glory to glory" suggests not a static possession but a dynamic ascent. There is always more. The transformation of theosis has no ceiling in this life because the Christ we are being conformed to is inexhaustible in His glory.
The mountain vision was not a preview of what Jesus alone could experience. It was a preview of what His people would experience by participation in Him.
Declarations
- ✦ I am a partaker of the divine nature — participating by grace in what Christ is by nature. (2 Peter 1:4)
- ✦ I am being conformed to the image of Christ — this is God's predestined purpose for my life. (Romans 8:29)
- ✦ I am being transformed from one degree of glory to another as I keep my face turned toward the Lord. (2 Corinthians 3:18)
- ✦ God who began a good work in me will carry it on to completion — my transformation is His project. (Philippians 1:6)
Prayer
Father, I want to know what Peter promised — not just to believe in Your nature but to participate in it. Transform me from the inside out, from one degree of glory to another, until what is true of Christ becomes true of me. I turn my unveiled face toward You. Do in me what only Your Spirit can do, and let the world see something of You in what I am becoming. In Jesus' name, Amen.
Think about it
If theosis is the goal — becoming more fully like Christ — what area of your life is showing the most growth right now? What area is most resistant to transformation?
I will turn my face toward Christ daily, cooperate with the Spirit's transforming work, and trust that the God who began this process in me will see it through to completion — one degree of glory at a time.
