Flesh vs Spirit in Galatians 5:16-25: Walk by the Spirit
Short answer: Galatians 5:16-25 answers the flesh vs Spirit question by telling believers to walk by the Spirit. The flesh and the Spirit are opposed to each other, so the Christian life is a real conflict, not a settled truce. Paul does not command us to manufacture our own goodness. He commands us to depend on the Spirit, who produces his fruit in us. The passage is both a warning and a promise. It warns that the works of the flesh are evident and serious, and it promises that those who belong to Christ Jesus have crucified the flesh with its passions and desires. Walking by the Spirit is the ordinary Christian life, lived in reliance on God rather than in self-confidence.
What Paul means by walking by the Spirit
Galatians 5:16 says, "But I say, walk by the Spirit, and you won’t fulfill the lust of the flesh." The word walk here is not a single dramatic decision but a way of life. In Greek it is a present imperative, which means keep on walking, keep on depending, keep on following. Paul is not asking for a mountaintop experience. He is describing the daily direction of a life. A walk is made of many small steps, and most of them seem unremarkable. The Christian life is formed the same way. It is not one great victory over the flesh but a thousand small choices to follow the Spirit rather than indulge the old desires.
Notice also that Paul says walk by the Spirit, not walk according to a rulebook. The Galatian churches were being pulled toward adding law-keeping to the gospel, as if obedience to regulations could finish what the Spirit started. Paul insists that the Spirit himself is the guide. This does not mean the law of God is unimportant. It means the law cannot produce the life God requires. Only the Spirit can. So Paul puts the Spirit in the place the false teachers put their rules. The question is not merely what you do, but who is leading you as you do it.
There is a promise attached to the command, and it is easy to miss. Paul says that if you walk by the Spirit, you won’t fulfill the lust of the flesh. He does not say you will never feel the pull of the flesh. He says you will not carry it out. The desire may rise, but it need not rule. This is important for anyone who has despaired over lingering temptation. The presence of a strong desire is not the same as the act of sin. Paul’s promise is about what you do with the pull, not whether the pull exists. The Spirit gives a way of escape in the moment of testing.
Walking by the Spirit also rules out two errors. One is complacency, the idea that since we are forgiven we can indulge the flesh without consequence. The other is self-reformation, the idea that we can fix ourselves by sheer willpower. Paul rejects both. The flesh is not tamed by ignoring it, and it is not defeated by our own strength. It is opposed by the Spirit, and only the Spirit can win. So the Christian life is a dependent life. We do not wait for the Spirit to do everything while we do nothing, and we do not charge ahead as if everything depends on us. We walk.
Why the flesh and the Spirit are opposed
Galatians 5:17 explains the tension: the flesh and the Spirit are in conflict. Paul says they oppose each other so that you cannot simply do whatever you want. This verse tells us that the Christian life is not neutral ground. There is a war on. Anyone who has tried to follow Christ knows the experience. You want to do good, and the old appetites pull the other way. You resolve to pray, and your mind wanders toward the very thing you meant to leave behind. Paul is not describing a defect in the gospel. He is describing the normal Christian experience this side of glory.
The word flesh in Paul does not mean the body as such. The body is not evil; God made it and will raise it. Flesh means the whole fallen human nature in its weakness and rebellion, the self turned away from God and curved in on itself. That is why the works of the flesh in verses 19 to 21 include things like idolatry and sorcery, which are not bodily sins at all, alongside sexual sins. The flesh is a whole orientation of life, not just a set of bad habits. It is the old humanity acting out what it is. The Spirit, by contrast, is God himself at work in us, producing a life that the flesh can never produce.
Because the two are opposed, Paul says they are mutually exclusive as ruling powers. You cannot have the flesh as your master and the Spirit as your master at the same time. That does not mean a believer never sins. It means a believer cannot live comfortably in sin. The Spirit within will not allow it. He convicts, he grieves, he draws us back. If there is no conflict at all, that is a serious sign. The presence of the struggle is evidence that the Spirit is at work. The person who has given up the fight entirely has reason to examine whether the Spirit is in them at all.
This is why Paul writes the way he does to the Galatians. They were tempted to treat the Christian life as a matter of external conformity, and Paul says the real battle is internal. The opponents of the gospel wanted visible markers. Paul wanted a life produced by the Spirit. You can manage external behavior for a while without any inward change. You cannot produce the fruit of the Spirit without the Spirit. The conflict Paul describes is the evidence that God is at work in you, conforming you to Christ and refusing to leave you as you were.
The works of the flesh are evident
In Galatians 5:19-21 Paul lists the works of the flesh. The list begins with sexual immorality, impurity, and sensuality, moves to idolatry and sorcery, then to hostility, strife, jealousy, outbursts of anger, selfish ambition, divisions, and envy. He ends with drunkenness and carousing and adds, and things like these. The list is not exhaustive, and Paul says so. But it is representative. It shows the breadth of the flesh. Some items are bodily, some are relational, some are religious. The flesh is not just about what you do in private. It is also about how you treat your neighbor and how you worship.
What strikes a careful reader is how many of these works are sins of the tongue and the temper. Jealousy, anger, selfish ambition, and division are not usually counted among the scandalous sins. Yet Paul places them in the same list as sexual immorality. This should humble anyone who has prided themselves on outward morality while nursing a bitter spirit. The flesh is subtle. It can look respectable. A church can be full of people who avoid the first sins on the list while practicing the later ones. Paul does not let us pick which parts of the flesh we will tolerate.
Paul also gives a solemn warning. He says that those who practice such things will not inherit the kingdom of God. This is not a threat to believers who stumble. It is a warning about a settled pattern. The present tense matters. Paul is describing people whose ongoing practice is the works of the flesh, not people who fall and repent. The difference between a believer and an unbeliever is not that the believer never sins. It is that the believer does not make peace with sin. John says the same thing when he writes that no one who is born of God practices sin. The warning is real, and it is meant to wake us up, not to drive us to despair.
So what do we do with this list? We read it honestly. We ask the Spirit to show us where we have tolerated what God calls flesh. We do not compare ourselves to our neighbors, because that is a way of managing the list rather than obeying it. We bring what we find to the cross. The point of the list is not to produce self-righteousness in those who avoid certain sins, nor to produce despair in those who have fallen into them. The point is to show us what the flesh produces so that we will flee to the Spirit who produces something else entirely.
The fruit of the Spirit grows, it is not manufactured
Galatians 5:22-23 gives the contrast: the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control. Notice the change from works to fruit. Works are what the flesh produces by its own effort. Fruit is what grows from a living root. You do not manufacture fruit; you cultivate the conditions in which it grows. That is a profound difference. The flesh produces by striving and self-assertion. The Spirit produces by dwelling and transforming. You cannot grit your teeth and become patient. You can, however, walk by the Spirit, and patience will grow as a byproduct of his presence.
The fruit is singular, not plural. Paul says the fruit of the Spirit, and then lists nine qualities. This suggests that the fruit is one thing with many facets, the character of Christ formed in us. You cannot pick and choose which facet you want. A person who has love but no self-control, or joy but no peace, has not yet fully borne the fruit. The Spirit is producing a whole character, not a set of isolated virtues. This is why growth in one area often exposes need in another. The Spirit is not satisfied with a partial likeness. He is conforming us to the whole Christ.
Look at where the fruit ends: self-control. That is a striking way to close the list, because it sounds like something we do. But it is the fruit of the Spirit, not the fruit of willpower. True self-control is not the flesh disciplining itself. It is the Spirit governing a life that has surrendered to him. This is the paradox of the Christian life. The more we depend on the Spirit, the more self-controlled we become, because the Spirit is producing that very quality in us. The person who tries hardest in their own strength becomes exhausted and proud. The person who abides in Christ bears fruit without realizing how.
Paul adds that against such things there is no law. This is his final answer to the legalists. If the Spirit is producing love, joy, peace, and the rest, then no law is needed to compel them. The law was never able to produce this fruit anyway. It could only command and condemn. The Spirit does what the law could not do. He writes the character of God on the heart. So the Christian life is not lawlessness. It is a life so governed by the Spirit that the law's demands are met from the inside out. This is the freedom Paul has been defending all along.
Those who belong to Christ have crucified the flesh
Galatians 5:24 says, "Those who belong to Christ Jesus have crucified the flesh with its passions and desires." This is one of the most striking statements in the passage. Paul does not say we should crucify the flesh, as if it were a project still ahead of us. He says we have crucified it. The tense points to something already done. When we came to Christ, we renounced the old master. We nailed the flesh to the cross, so to speak, and we do not go back and take it down. Conversion is a decisive break, not just an addition to an unchanged life.
But if the flesh is already crucified, why does the conflict continue? Because a crucified thing does not always stay dead immediately. Paul uses the image deliberately. A crucified man is condemned and finished, but he may still struggle and speak for a time. In the same way, the flesh has been judged and its authority broken, but its influence lingers. The believer is not fighting for victory over the flesh; they are fighting from victory over it. The old nature no longer has the right to rule. When it whispers that it is still in charge, we answer with the cross. It has been crucified. It does not get to command us anymore.
This is where many believers get confused. They think sanctification is about making the flesh better. But Paul does not say to reform the flesh. He says to crucify it and to walk by the Spirit. You do not train the old nature to behave. You put it to death and live in the new nature the Spirit gives. This is why Paul tells the Colossians to put to death their earthly members. The imagery is severe because the stakes are severe. Sin is not a pet to be managed. It is an enemy to be put to death. The Spirit gives the power, but we are called to act.
The verse also tells us what belongs to Christ. If you belong to Christ, this crucifixion is true of you. It is not something you must achieve to qualify. It is what has happened to everyone who has been united to him by faith. That is a great comfort. Your standing does not rest on how well you have managed the flesh this week. It rests on what Christ has done and on the Spirit who now lives in you. The evidence that you belong to Christ is not sinless perfection but a real break with the old life and a real desire for the new.
Keep in step with the Spirit
Galatians 5:25 draws the conclusion: if we live by the Spirit, let us also walk by the Spirit. The word Paul uses here for walk is different from the one in verse 16. It carries the idea of keeping in step, of marching in line with someone. It is the picture of a soldier staying in formation, or a traveler matching the pace of a companion. This is what the Christian life looks like in practice. The Spirit is moving, and we move with him. He is not a distant guide whose instructions we consult occasionally. He is a person whose leading we follow step by step, day by day, moment by moment.
This means the Christian life is responsive, not merely scheduled. We can do all the right religious activities and still not be keeping in step with the Spirit. The Spirit may be leading us to speak to someone, to wait rather than act, to give rather than keep, to forgive rather than nurse a grudge. Keeping in step means hearing and obeying in the ordinary moments. It is not a mystical trance. It is a relationship. It is trust expressed in action. The person who keeps in step with the Spirit does not always know where they are going, but they know who is walking with them.
This also explains why Paul's two commands go together. He does not say walk by the Spirit in verse 16 and then give a different instruction in verse 25. He says the same thing twice because we need to hear it twice. The flesh is persistent, and we are forgetful. We drift toward self-effort on one side and toward complacency on the other. Both are ways of getting out of step. The remedy is the same both times. Turn from the flesh, turn to the Spirit, and keep walking. The Christian life is not a sprint. It is a long obedience in the same direction, sustained by the Spirit who never leaves us.
Finally, keeping in step with the Spirit is not a burden but a liberation. The flesh promises freedom and delivers slavery. The Spirit calls us to follow and gives us life. Every step with him is a step away from the corruption of the old nature and a step toward the likeness of Christ. We will not arrive fully in this life. But we are moving, and the one who began a good work in us will bring it to completion. So we walk. Not perfectly, but persistently. Not in our own strength, but in his. That is what it means to live by the Spirit.
Biblical fidelity check
No passage in Scripture establishes that the believer becomes sinless in this life. Paul wrote Galatians 5:16-25 to people who were already in Christ, and he still spoke to them about the works of the flesh. He also wrote elsewhere about the ongoing struggle, and in Romans 7 he describes the experience of wanting to do good but not doing it. The passage teaches that the Spirit produces real fruit, but it does not teach that the fruit is fully mature in every believer or that the fight is over. The command to walk by the Spirit is continuous, which means there is always more walking to do. Anyone who claims to have arrived, or who treats growth in grace as optional, has misread Paul.
A common misreading is to treat the flesh as the body and the Spirit as the soul, as if salvation were escape from physical existence. But the works of the flesh include idolatry, jealousy, and division, which are not bodily sins, and the fruit of the Spirit includes self-control, which is lived out in the body. Another misreading is to make the Spirit's fruit something we produce by discipline, as though the passage were a self-improvement program. But Paul says it is the fruit of the Spirit, not the fruit of our effort. A third misreading is to use the passage as a way of judging others. Paul addresses all the Galatians as brothers and sisters; his aim is their growth in Christ, not the production of a self-righteous measuring stick.
Other passages that speak to Galatians 5:16-25
Paul's teaching in Galatians does not stand alone. His most sustained explanation of life in the Spirit is found in the letter to the Romans, where he explains that those who are in Christ have the Spirit and set their minds on the things of the Spirit. That is why this Romans Bible Study Guide: Sin, Grace, Justification, and Life in the Spirit is a helpful companion. But the fruit of the Spirit in particular is often misunderstood, so see this treatment of What does Galatians 5 mean by fruit of the Spirit? The same Spirit also builds unity in the church, which is the burden of What Does 1 Corinthians 1:10 Mean? Context, Theology, and Application and of What Does 1 Corinthians 1:9 Mean? Context, Theology, and Application, because the God who called us into fellowship with his Son will not leave us to walk alone.
Frequently asked questions
Does walking by the Spirit mean I never have to fight temptation?
No. Paul says the flesh and the Spirit are opposed to each other, which means the fight is real for every believer. Walking by the Spirit does not remove temptation. It gives you a way to stand in it. The promise of Galatians 5:16 is that you will not carry out the desire of the flesh when you rely on the Spirit. But that reliance is active, not passive. You still resist, you still pray, you still choose. The difference is that you are not fighting alone, and you are not fighting to earn God's love. You are fighting from a secure position in Christ, with the Spirit's power at work in you.
Is the fruit of the Spirit a list I should try to achieve?
It is not a checklist to conquer by willpower. Paul calls it fruit because it grows from a root. You cannot manufacture love or joy by deciding harder. What you can do is walk by the Spirit, abide in Christ, and let the Spirit do his work. That usually looks like ordinary faithfulness: prayer, Scripture, fellowship, obedience in small things. Over time the character qualities appear. You may not notice them as they grow, but others often will. The point is not to strain after nine separate virtues but to stay close to the one who produces them all.
What if I keep failing and the flesh seems to win?
Failure is painful, but it is not the end. Paul wrote this passage to real churches with real problems. The presence of struggle is not proof that you are not a Christian; it may be proof that the Spirit is at work in you. The response to failure is not to give up and not to punish yourself, but to return to Christ. Confess, receive forgiveness, and keep walking. If a pattern of sin persists and you feel stuck, bring it into the light with a mature believer who can help you. Growth is rarely instant, and God is patient with his children.
