One of the great cruelties we inflict on ourselves as believers is to keep living as though we are still who we used to be. The gospel declares something better — and it is not wishful thinking.

Paul does not say the believer is improving. He does not say old things are fading. He says they have passed away — the Greek aorist tense, a completed action. Something happened. A line was crossed. A nature was exchanged. And in its place: new creation, using the same Greek word, kainē ktisis, that the New Testament uses for the renewal of all things at the end of the age.

You are not a renovation. You are a new creation. The difference matters enormously.

What “in Christ” actually means

The phrase “in Christ” appears over 160 times in Paul’s letters. It is not decorative language. It is locational language — describing a union so real and so complete that everything true of Christ becomes legally and spiritually true of the one who is joined to Him by faith.

When Christ died, you died. When He was buried, your old self was buried. When He rose, you rose — to a new kind of life that did not exist before. This is why Paul can say in Galatians 2:20: “I have been crucified with Christ; it is no longer I who live, but Christ lives in me.” The old “I” — the self defined by sin, shame, and separation from God — is gone. The new “I” is indwelt and defined by Christ Himself.

Why we still feel like the old self

If the new creation is a completed reality, why do we still wrestle with old patterns, old temptations, old shame? This is one of the most honest and important questions in the Christian life — and Paul does not dodge it.

The answer is the distinction between who we are and how we feel, between our position and our experience. The new creation is a spiritual and legal reality that must be progressively realised in our daily lives — through renewing of the mind, through the Spirit’s work, through the slow but certain process of sanctification. The seed of new creation is fully planted. The full harvest is still unfolding.

But here is the crucial point: you grow from your new identity, not toward it. You do not become a new creation by behaving like one. You behave like one because you already are.

Life application: living from the new creation forward

Behold — all things have become new

The word Paul uses — behold — is a word of announcement, of wonder, of pointing to something that deserves your full attention. Paul is not making a quiet theological observation. He is gesturing at something astonishing and saying: look at this. Look at what has happened to you.

You are not who you were. You are not defined by what you did, what was done to you, or what the world said you were. You are defined by what Christ has made you — and what He has made you is brand new, indwelt by His Spirit, held in His righteousness, and headed toward a glory that has not yet been fully revealed.

That is who you are. Live from there.
