Have you ever tried to live the Christian life in your own strength? You make resolutions to read the Bible more, pray consistently, avoid temptation, and show kindness to everyone. For a while, it works, but eventually you grow weary. Frustration sets in because no matter how hard you try, the old patterns of sin creep back. The apostle Paul understood this struggle perfectly. In Galatians 5, he offers the solution: stop relying on fleshly efforts and start living by the Spirit.
Paul writes in Galatians 5:16-18, “I say then: Walk in the Spirit, and you shall not fulfill the lust of the flesh. For the flesh lusts against the Spirit, and the Spirit against the flesh; and these are contrary to one another, so that you do not do the things that you wish. But if you are led by the Spirit, you are not under the law.”
Here, Paul presents two opposing forces at work in every believer: the flesh and the Spirit. The flesh represents our old, sinful nature, still present even after salvation. It pulls us toward self-centered desires, anger, envy, immorality, and pride. The Spirit is the Holy Spirit dwelling within us, empowering us toward holiness, love, and obedience to God.
These two are in constant conflict. The flesh and the Spirit are contrary to one another. This tension explains why we sometimes feel torn between what we want to do and what we know is right. Paul says the result of this battle is that we often fail to do the good we desire (see also Romans 7:15-20).
The key to victory is not more willpower or stricter rules. It is walking in the Spirit. To “walk” means to live daily, to conduct our lives moment by moment under the Spirit’s leadership. When we do this, we do not fulfill the lust of the flesh. The Spirit leads us away from sin and into righteousness.
Paul adds an important clarification in verse 18: if you are led by the Spirit, you are not under the law. This connects back to the entire letter. The Galatians were being pressured to live under the law, as if grace were not enough. Paul insists that the Spirit’s leadership replaces the law’s supervision. The law could command and condemn, but it could not empower. The Spirit both commands and enables. He produces the very life the law demanded but could never create.
Later in the chapter, Paul urges believers to keep in step with the Spirit. Galatians 5:25 says, “If we live in the Spirit, let us also walk in the Spirit.” The first part is a fact: every true believer lives in the Spirit because the Spirit indwells us at conversion (Romans 8:9). The second part is an exhortation: since this is true, let us actively walk by the Spirit every day. It is not automatic; it requires dependence, surrender, and obedience.
How do we practically walk in the Spirit? It begins with recognizing our weakness and turning to Him. We confess sin quickly when the flesh rises up. We pray for His filling and guidance (Ephesians 5:18). We immerse ourselves in Scripture, which the Spirit uses to renew our minds (Romans 12:2). We obey promptings to love, forgive, serve, and speak truth. As we yield, the Spirit strengthens us.
The beautiful result is the fruit of the Spirit listed in Galatians 5:22-23: “But the fruit of the Spirit is love, joy, peace, longsuffering, kindness, goodness, faithfulness, gentleness, self-control. Against such there is no law.” Notice that Paul calls it fruit, not works. Fruit grows naturally from a healthy tree. When we abide in Christ and walk by the Spirit, these qualities emerge organically. They are not forced through self-effort but cultivated by His presence.
Contrast this with the works of the flesh in verses 19-21: adultery, idolatry, hatred, jealousy, drunkenness, and more. Those who practice such things will not inherit the kingdom of God. The point is not that believers never sin, but that a life dominated by the flesh contradicts the new birth. A Spirit-led life produces different evidence.
This teaching brings freedom from legalism and defeat. Many Christians live defeated because they try to fight the flesh with fleshly tools: more rules, more guilt, more striving. Paul says the answer is not more law but more of the Spirit. The same Spirit who raised Christ from the dead dwells in us and gives life to our mortal bodies (Romans 8:11).
Walking by the Spirit also guards against license. Some might think freedom from the law means freedom to sin. Paul already addressed that in Galatians 5:13: “For you, brethren, have been called to liberty; only do not use liberty as an opportunity for the flesh, but through love serve one another.” True liberty serves others in love, and the Spirit leads us into that kind of life.
If you feel stuck in a cycle of trying harder and failing, stop. Look to the Spirit. Admit your inability and ask Him to lead you. Yield to His gentle promptings. Trust that He is at work in you both to will and to do for God’s good pleasure (Philippians 2:13).
The Christian life is not about gritting your teeth and doing better. It is about abiding in Christ and letting the Spirit live through you. As you walk in Him, sin loses its grip, and the fruit of righteousness grows.
May we daily choose to walk by the Spirit. May we experience the freedom, joy, and power that come from depending on Him rather than on ourselves. For it is the Spirit who leads us into all truth, conforms us to Christ, and glorifies God in our lives. Thanks be to God for the gift of His indwelling Spirit. Let us keep in step with Him today and every day.
