Put Off the Old Man: What Ephesians 4:22-24 Requires
Short answer: Ephesians 4:22-24 tells believers to do three things: put away the old man, be renewed in the spirit of their mind, and put on the new man. The old man is not a separate person or a demon; it is the former way of life that grows corrupt after the lusts of deceit. Paul writes that you put away, as concerning your former way of life, the old man that grows corrupt after the lusts of deceit. The command is decisive, but the power is not yours alone. Romans 8:13 says, For if you live after the flesh, you must die; but if by the Spirit you put to death the deeds of the body, you will live. So the Christian puts off sin seriously, repents specifically, and depends on the Spirit rather than on willpower or personality change.
What Paul actually commands in Ephesians 4:22-24
Paul's language in Ephesians 4 is clothing language. He is not describing a mood or a gradual personality adjustment; he is describing taking off a garment and putting on another. That you put away, as concerning your former way of life, the old man that grows corrupt after the lusts of deceit is a direct command issued to people who are already in Christ. The verb is not a suggestion for advanced believers. It is addressed to the whole church.
Notice the tense and the shape of the sentence. The old man belongs to a former way of life. Paul does not say the old man is simply weak or immature; he says it grows corrupt after deceitful desires. The corruption has a direction. It feeds on lies, and it gets worse when fed. That is why the command is to put it away rather than to manage it, moderate it, or occasionally indulge it.
The command also assumes that something has already changed. Paul is not telling unbelievers to try harder. He is telling people who have been made new in Christ to live out what they now are. The putting off is real work, but it is the work of someone who has already been transferred into a new identity, not the work of someone trying to earn one.
What the old man is, and what he is not
The old man is the former self shaped by sin, the pattern of life that belonged to you before Christ. It is not a second person living inside you, and it is not a demon that must be exorcised. It is you as you were, and it persists as a set of habits, reflexes, and desires that must be rejected. When Paul says put away the old man, he means stop living as though that were still your identity.
This distinction matters pastorally. If you treat the old man as a separate entity, you will excuse yourself: that was not really me, that was the old man. But Paul does not allow that escape. He tells you to put him away. You are responsible for the deeds of the body, and you are the one who must refuse them. The old man has no independent right to your hands, eyes, or tongue.
At the same time, the old man is not merely a list of bad behaviors. He is a way of life with a logic to it. He trusts deceitful desires, justifies himself, and builds habits that reinforce the lie. That is why Paul moves from the general command in Ephesians 4 to very specific sins in the verses that follow. The old man must be named in concrete terms, not left as a vague regret.
Renewed in the spirit of your mind
The middle command in Ephesians 4:22-24 is the one most often skipped. Paul says to be renewed in the spirit of your mind. This is not optional decoration around the put-off and put-on; it is the hinge. If the old man grows corrupt after the lusts of deceit, then the remedy must involve the mind, because it was the mind that believed the deceit in the first place. Renewal is not merely trying to feel differently.
Romans 12:2 makes the same connection, and Colossians 3:10 says the new man is being renewed after the image of his Creator. The mind is where the old man is dismantled. Lies are replaced with truth, distorted pictures of God are corrected, and desires are reordered. This is why Scripture reading, prayer, and honest teaching are not extras for serious Christians. They are the ordinary means by which the Spirit renews the mind.
This also explains why willpower alone fails. You can white-knuckle a behavior while keeping the belief that produced it. The behavior will return, because the root was never touched. Renewal in the mind is slower and less dramatic than a fresh start, but it is the part of the process that makes the putting off stick.
Put on the new man: replacement, not just removal
Paul does not stop at removal. He says put on the new man, which after God has been created in righteousness and holiness of truth. The Christian life is not a vacuum; it is an exchange. If you only take off anger but do not put on patience, the space will fill with something else, often something uglier. Ephesians 4 goes on to name the replacements: the thief must steal no more but labor, the corrupt talk must be replaced with grace-filled speech, bitterness with forgiveness.
Colossians 3:5-10 uses the same structure: Put to death therefore your members which are on the earth: sexual immorality, uncleanness, depraved passion, evil desire, and covetousness, which is idolatry. Then Paul adds that the new man is being renewed to knowledge after the image of the one who created him. The putting off is severe, but it is never the whole picture. The new man is being renewed, which means the process continues.
This is important because some teaching on mortification stops with severity. It produces grim, self-focused Christians who are always hunting for sin but never growing in love. Paul's pattern is both: kill what belongs to the old life, and actively put on the character of Christ. You cannot put off what you will not name, and you cannot put on what you never practice.
Dead to sin, alive to God: the ground of the command
The command to put off the old man rests on a finished fact. Romans 6:6-13 says, knowing this, that our old man was crucified with him, that the body of sin might be done away with, so that we would no longer be in bondage to sin. The old man was crucified with Christ. Paul is not telling you to crucify him so that he might be defeated; he is telling you to reckon as true what God has already done, and to stop letting a defeated power rule you.
That is why the Christian's fight is not a fight for victory but from victory. You are told not to let sin reign in your mortal body, because it no longer has the right to rule. The old man is a usurper, not a rightful king. When you put him off, you are aligning your daily life with the verdict God has already pronounced over you in Christ.
This also guards against despair. If you fail, the answer is not to conclude that the gospel did not work. The answer is repentance, renewed faith in the finished work of Christ, and a return to the fight. The command is serious, but the foundation is grace. Titus 2:11-12 says, For the grace of God has appeared, bringing salvation to all men, and it goes on to say this grace trains us to renounce ungodliness. Grace is not opposed to putting off sin; grace is what teaches us to do it.
How this is put into practice without moralism
Practically, putting off the old man begins with naming specific sins rather than general categories. Not I have a temper, but I speak harshly to my spouse when I am tired. Not I struggle with lust, but here is the time, the device, and the pattern. The old man thrives in vagueness. When you name a sin, you can repent of it and take concrete steps against it.
Second, replace rather than merely resist. Put on the new man in the specific place where the old man lived. If the old habit was gossip, put on speech that builds up. If it was laziness, put on honest work. If it was anxiety, put on prayer with thanksgiving. The pattern in Ephesians and Colossians is consistently exchange, not just subtraction.
Third, do this by the Spirit, in community, and over time. Galatians 5:16 says, But I say, walk by the Spirit, and you won't fulfill the lust of the flesh. This is not a solo project. Faithful Christians differ on how much of this process is instantaneous and how much is gradual, and on how to describe the relationship between our effort and the Spirit's power. But almost all agree on this: the fight is real, the outcome is secure in Christ, and no one wins it alone.
Where this appears across Paul's letters
Paul's put-off, put-on pattern is not unique to Ephesians. In Colossians 3:5-10 he tells believers to put to death earthly members and to put off the old man with his practices, while the new man is being renewed. In Romans 6 he argues that the old man was crucified with Christ so that the body of sin might be done away with. In Galatians 5 he contrasts the works of the flesh with the fruit of the Spirit and says walking by the Spirit is the way you do not fulfill the flesh's lust.
The consistency is striking. Paul everywhere treats sin as something to be decisively rejected, not managed. He everywhere grounds that rejection in union with Christ. And he everywhere expects the Spirit to be the power behind it. Ephesians 4:22-24 is not a stray command; it is a concentrated statement of the whole Pauline pattern.
This means you can read Ephesians 4 alongside Romans 6 and Colossians 3 without tension. They are saying the same thing from different angles: you have died with Christ, so put to death what belongs to the old life, and put on the new life that Christ has created in you. The imperative rests on the indicative, and the indicative gives the imperative its power.
Biblical fidelity check
What Ephesians 4:22-24 establishes is a clear threefold command to believers: put away the old man, be renewed in the mind, and put on the new man. It establishes that the old man belongs to the former way of life and is characterized by deceitful desires. It establishes that the new man is created in righteousness and holiness of truth. It does not establish that the old man is a separate being, that believers can lose their salvation by failing to put him off, or that the process is completed instantly.
A common misreading is that putting off the old man means trying harder to be good, using willpower and shame until the behavior changes. That is moralism, and it fails because it ignores the renewed mind and the Spirit's power. Another misreading treats the command as only positional, as if nothing needs to change because the old man was already crucified. But Paul commands action. The text does not establish that the fight is optional; it establishes that the fight is empowered.
Other passages that speak to Ephesians 4:22-24
Paul's letters repeatedly interpret the put-off/put-on pattern in the light of union with Christ and life in his body. These studies fill in the wider argument: What Does Colossians 1:23 Mean? Context, Theology, and Application, Colossians 1: Paul's Prayer and Christ's Supremacy, Colossians 2: Fullness and Freedom in Christ, and What Does Colossians 3:1 Mean? Context, Theology, and Application. Read together, they show that putting off the old man is not a self-help project but the outworking of a life already hidden with Christ in God.
Frequently asked questions
Is the old man a demon or a separate person inside me?
No. The old man in Ephesians 4:22 is the former way of life, the pattern of thinking and acting that belonged to you before Christ. Paul calls it the old man because it is the old you, not a foreign entity. It should not be blamed as though it acted independently of your choices. At the same time, it is not a harmless weakness; it grows corrupt after deceitful desires and must be decisively put away. Treating it as a separate person leads to excuses rather than repentance.
Does putting off the old man save me or prove I am saved?
It does neither in the sense of earning salvation. Ephesians 4:22-24 addresses people who are already in Christ and commands them to live accordingly. Scripture consistently grounds the command in what God has already done. Romans 6:6 says the old man was crucified with him. Obedience is the fruit and evidence of salvation, not its price. Faithful Christians differ on how to describe perseverance, but they agree that believers are called to real, ongoing repentance and that their standing rests on Christ's work, not their performance.
How long does it take to put off the old man?
Scripture presents it as a decisive break and an ongoing process. The aorist commands in Ephesians 4 call for a decisive putting away, while Colossians 3:10 says the new man is being renewed, which implies continuation. In practice, some patterns fall quickly and others require years of repentance, replacement, and help from mature believers. The New Testament never promises a fixed timeline. It promises that those who by the Spirit put to death the deeds of the body will live, and that God finishes what he begins.
