Ephesians 4:17-24

“But that is not the way you learned Christ.” Paul places that sentence in the middle of a sober contrast. He is writing to believers in Ephesus, many of them Gentiles, and he tells them that they must no longer walk as the nations walk. Their former way of life was marked by darkened understanding, alienation from God, hardness of heart, and desires that promised freedom while quietly deepening corruption.

Paul is not speaking as though Christians are better by nature than anyone else. He has already said that salvation is by grace, through faith, and not a result of works. The difference is not that believers found wisdom in themselves. The difference is Christ. They have heard him. They have been taught in him. Truth is in Jesus.

That phrase matters. Christianity is not merely the adoption of a better moral code. It is not the polishing of the old self until it becomes respectable. Paul describes a far deeper change. The old self, shaped by deceitful desires, is to be put off. The spirit of the mind is to be renewed. The new self, created after the likeness of God, is to be put on.

There is both gift and obedience here. The new self is created. God brings into being what we could not manufacture. Yet believers are also called to put off and put on. Grace does not leave us passive before sin. It joins us to Christ and then teaches us to walk in the life he gives.

This can expose a quiet weariness in us. We may confess that we belong to Christ and still find old patterns close at hand. Old reactions. Old cravings. Old ways of protecting ourselves. Old thoughts we have rehearsed so long they feel like truth. The passage does not invite us to pretend those things are gone. It names them clearly. The former manner of life is corrupt through deceitful desires. Sin deceives before it destroys. It offers relief, control, belonging, pleasure, vindication, or escape. It speaks with urgency. It rarely tells us where it will lead.

Christ tells the truth. He does not merely forbid the old life; he reveals its emptiness. He does not shame his people back into holiness; he teaches them from within the reality of union with himself. To have “learned Christ” is more than having learned facts about him. It is to have been brought under his lordship, formed by his truth, and drawn into a life that bears his likeness.

So the Christian life is not a desperate attempt to become someone God might finally accept. It is the daily turning away from what no longer belongs to us because, in Christ, God has made us new. The old self may still clamor. It may still feel familiar. But it is no longer your deepest identity. It is a garment to be taken off, not a name to be worn.

And the new self is not an image you invent. It is created after the likeness of God in true righteousness and holiness. This is a humbling comfort. Holiness is not self-expression baptized in religious language. It is the life of God’s renewed people becoming visible in ordinary places: in speech, in desire, in patience, in repentance, in hidden choices, in the slow reordering of loves.

You may feel the distance between what you believe and how you live. Paul does not minimize that struggle. But he does place it inside a stronger truth. You have learned Christ. Truth is in Jesus. The life he gives is not fragile, and the renewal he begins reaches even the mind, where so many battles are quietly fought.

Return, then, to the One who teaches you. Bring the old patterns into the light without calling them your home. Receive again the newness God has created in Christ. The Lord who saved you by grace is also forming you in righteousness and holiness, patiently and truly, until your life more fully bears the shape of the One to whom you belong.
