The New Man in Ephesians 4: Put Off the Old Self
Short answer: The new man is the person God creates in everyone who is joined to Christ. Ephesians 4:17-24 tells believers to no longer walk as the rest of the Gentiles walk and to put off the old man and put on the new man, which was created in righteousness and holiness of truth. This is not a personality upgrade or a list of moral techniques. It is a new identity given by God that must now be lived out. The old man belongs to the former way of life and is corrupt through deceitful lusts. The new man is created by God, renewed in the spirit of the mind, and marked by truth and holiness. Paul does not present this as optional for mature Christians. He presents it as the ordinary shape of Christian obedience.
What Paul means by the old man
When Paul writes about the old man, he is not describing an unfortunate personality trait or a bad habit that needs polishing. He is describing a whole way of being human apart from God. The old man belongs to the former conduct, and Paul says it is corrupted by deceitful lusts. The mind is darkened, the understanding is alienated from the life of God, and the will is bent toward futility. This is the condition Ephesians 2:1-10 describes when it says, "You were made alive when you were dead in transgressions and sins." The old man is not merely sick. He is dead and needs resurrection life, not resolute self-improvement.
Paul's language in Ephesians 4:17-24 is corporate as well as personal. He tells the church not to walk as the rest of the Gentiles walk, in the futility of their mind. The contrast is between two entire ways of life, two loyalties, two directions. The old man is not just a private inner state; he is a pattern of life shaped by the age around us. That is why Paul does not say, try harder to be good. He says, put off the old man, because it belongs to a life you have already been rescued from in Christ.
It is important to keep the old man distinct from the new man without pretending the old man has no remaining influence. Paul can say in Romans 6:1-14 that believers have died to sin, and yet in the same letter he urges them not to let sin reign in their mortal bodies. The old man has been dealt a decisive blow at the cross and in baptism, but the habits of the old life still press for control. The Christian life is the ongoing practice of reckoning the old man dead and refusing to hand him the reins again.
The new man is created, not manufactured
The most important word in Ephesians 4:24 is created. Paul does not say the new man is achieved, improved, or assembled from good intentions. He says it was created in righteousness and holiness of truth. Creation is God's work. When Paul describes salvation in Ephesians 2:1-10, he says believers are God's workmanship, created in Christ Jesus for good works, which God prepared before that they should walk in them. The new man is a divine creation, not a human project. That is why the call to put on the new man is not a call to become someone you are not. It is a call to become who you already are in Christ.
This is where the new man differs from every self-help program. Self-help says, look inside yourself, find your potential, and build a better version. The gospel says, you were dead, and God made you alive. The new man is not latent potential waiting to be unlocked. He is a gift given to people who could not give themselves life. Colossians 3:1-11 carries the same logic when it tells believers to seek the things that are above, because their life is hidden with Christ in God. The new man lives from a life that is not his own.
Because the new man is created, the Christian life is fundamentally responsive rather than inventive. We do not invent holiness. We receive it, wear it, and live it out. The new man is created in righteousness and holiness of truth, which means the pattern of his life is God's own character. His truth is not the world's shifting narrative. His righteousness is not self-righteousness. His holiness is not rule-keeping for its own sake. It is the character of the God who made him, reproduced by the Spirit in a life that has been made new.
Putting off and putting on is a daily practice
Paul's command uses clothing language: put off the old man and put on the new man. Clothing is something you do each day. You do not put on a shirt once for all and never think about it again. In the same way, the Christian life involves a daily, deliberate renunciation of the old patterns and a daily, deliberate embrace of the new identity. This is not salvation by works, because the clothing is already provided. But it is obedience, because the clothing must actually be worn. The old man is not removed by wishing he were gone. He is put off by a decision of the will, one situation at a time.
Putting off is concrete. In the verses that follow Ephesians 4:24, Paul names specific things: lying, stealing, corrupt speech, bitterness, wrath, clamor. He does not let the new man remain an abstraction. He sends the reader into the ordinary details of life: how you talk to your neighbor, how you handle your temper, what you do with your hands, what comes out of your mouth. The new man is not merely a doctrine to affirm in church. He is a way of speaking to your spouse, handling money, responding to insult, and doing your work. The command to put off the old man reaches into the kitchen, the office, the group chat, and the checkbook.
Putting on is equally concrete. It is not enough to stop lying; we must speak truth. It is not enough to stop stealing; we must labor and give. It is not enough to stop being bitter; we must forgive as God in Christ forgave us. The new man has positive shape. He is not defined only by what he avoids but by what he loves, speaks, and does. This is why the Christian life cannot be reduced to a list of prohibitions. The new man is created in righteousness and holiness of truth, so his life has content. He tells the truth because he belongs to the God who is truth. He works because he belongs to the God who gives.
How the cross makes the new man possible
None of this makes sense without the cross. Paul writes in Galatians 2:20, "I have been crucified with Christ, and it is no longer I who live, but Christ lives in me." The old man was not reformed; he was crucified. That is the only reason Paul can tell believers to put him off. If the old man were still alive and well, telling him to put himself off would be absurd. But the old man has already been executed with Christ, and the new man has been raised with him. The Christian life is therefore not a battle to kill a living enemy but a battle to stop feeding a corpse. That is a very different kind of struggle, and it is filled with hope.
Second Corinthians 5:14-17 makes the same point from another angle. Paul says that one died for all, therefore all died, and that if anyone is in Christ, he is a new creation. The old things have passed away. The new creation is not a repaired version of the old. It is a genuinely new thing, brought into being by the death and resurrection of Christ. This is why Paul can speak with such confidence about the new man. He is not optimistic about human nature. He is confident about the finished work of Christ. What God creates, God sustains. What God raises, God keeps raising.
The cross also settles the question of identity. If you are in Christ, your old identity no longer has the final word over you. You are not defined by your former lusts, your former failures, or the futility of a mind alienated from God. You are defined by the one who loved you and gave himself up for you. That is the foundation for the daily practice of putting off and putting on. We do not put off the old man in order to become the new man. We put off the old man because we have already been made new. Obedience flows from identity, never the other way around.
Renewal in the spirit of the mind
Paul says believers are renewed in the spirit of their mind. Renewal is the inward work that makes the outward life possible. If the old man is characterized by the futility of the mind, the new man is characterized by a mind being made new. This is not merely positive thinking or mental discipline. It is the Spirit of God reshaping how we see God, ourselves, sin, and the world. A renewed mind does not automatically assume the world's assumptions. It learns to think God's thoughts after him. This is why Scripture reading, prayer, and the life of the church are not extras. They are the ordinary means by which the mind is renewed.
Renewal is also progressive. Paul does not say the mind was renewed once and is now finished. He speaks of an ongoing renewal. There are days when a believer sees clearly and days when the old patterns of thought crowd back in. That is normal. The presence of the struggle is not evidence that the new man is absent. It is evidence that the old man is being put off. A person who has been made new will increasingly find the old ways of thinking unsatisfying, not because they have become stronger than sin on their own, but because the Spirit is at work in them, changing what they love and how they see.
This is where the church matters. Paul writes Ephesians 4 to a congregation, not to isolated individuals. The new man is put on in community. We speak truth to one another, forgive one another, bear with one another, and are taught by one another. A believer who tries to put off the old man alone will find it much harder than one who is surrounded by people who know him, pray for him, and tell him the truth. The new man is personal, but he is not private. He is created by God and formed in the family of God.
What the new man does not mean
The new man does not mean sinless perfection in this life. Paul commands believers to put off the old man precisely because the old man keeps showing up. If the new man meant sinlessness, the command would be unnecessary. Christians still sin, and 1 John addresses that reality plainly. What changes is the direction and the default. The old man used to reign unchallenged. Now he is a usurper who must be resisted. The presence of ongoing temptation is not a denial of the new creation. It is the arena in which the new creation is lived out.
The new man does not mean the erasure of personality, temperament, or personal history. God does not save people by turning them into identical copies. The new man is created in righteousness and holiness of truth, but that holiness takes shape in a quiet person and a loud person, an introvert and an extrovert, a former thief and a former Pharisee. Sanctification does not delete your background; it redeems it. Paul, the former persecutor, became Paul the apostle. His gifts and intensity were not erased. They were turned toward a new master and a new end.
The new man also does not mean that effort is unnecessary. Some believers hear creation language and conclude that since God creates the new man, they can be passive. Paul does not draw that conclusion. He commands, put off, put on, be renewed. The Christian life is a partnership in which God does the creating and the sustaining, and believers do the putting off and the putting on by his grace. Philippians 2:12-13 says to work out your own salvation with fear and trembling, for it is God who works in you both to will and to work, for his good pleasure. Effort and grace are not rivals.
Biblical fidelity check
Ephesians 4:17-24 establishes several things plainly. It establishes that unbelievers walk in the futility of their mind and are alienated from the life of God. It establishes that the old man is corrupt and must be put off. It establishes that the new man is created by God in righteousness and holiness of truth. It establishes that believers are commanded to live consistently with that new creation. It does not establish a detailed psychological model of the self, a timeline for sanctification, or a technique for overcoming specific sins. Those must be drawn from the whole of Scripture, not pressed out of these verses.
A common misreading treats the new man as a second, better self that exists alongside the old self, so that the Christian life becomes a tug-of-war between two equal inner persons. That reading flattens Paul's language and turns the cross into a stalemate rather than a victory. Paul does not describe two equal selves. He describes an old man who has been crucified with Christ and a new man who has been raised with him. The struggle is real, but it is not a fair fight. The old man is a defeated enemy who must be refused, not a co-regent who must be negotiated with. Another misreading treats the new man as something we produce by effort. That inverts the text. Paul says the new man was created. Our part is to put on what God has made, not to manufacture what only God can create. Both misreadings lead either to despair or to pride, and the passage leads to neither.
Other passages that speak to Ephesians 4:17-24
Several passages should be read alongside Ephesians 4:17-24. Colossians 3:1-11 gives a parallel call to put off the old and put on the new, with the added note that Christ is all and in all. Romans 6:1-14 explains the logic of dying to sin and living to God, grounding the new man in baptism and union with Christ. Second Corinthians 5:14-17 declares that anyone in Christ is a new creation, with old things passed away. Galatians 2:20 gives the personal center of the whole matter: the believer has been crucified with Christ, and Christ lives in him. These are not competing accounts. They are the same gospel seen from different angles, and together they keep the new man from becoming either a moral slogan or a private experience.

Frequently asked questions
Is the new man the same thing as the new nature?
The terms are often used interchangeably, and they overlap closely. The new man in Ephesians 4:24 is the person God creates in Christ, marked by righteousness and holiness of truth. The new nature in other translations reflects the same idea. What matters is that this newness is God's creation, not a human achievement, and that it is meant to be lived out in daily obedience. The terminology differs; the reality is one.
Does putting off the old man mean I will stop sinning entirely?
No. Paul commands believers to put off the old man because the old patterns continue to press in. The Christian life is a real struggle, and believers still sin. What changes is who is in charge and which direction the life is heading. The old man used to reign without resistance. Now he is resisted. Ongoing temptation is not proof that the new man is absent; it is the setting in which the new man is lived out by grace.
How do I actually put on the new man?
Begin with the identity God has given you. You have been crucified with Christ and raised with him. Then act on it in concrete ways. Tell the truth when lying would be easier. Work honestly. Forgive as you have been forgiven. Guard your speech. Let your mind be renewed by Scripture, prayer, and the teaching of the church. None of this earns the new man. It is how the new man, already created by God, learns to walk.
