What Are the Works of the Flesh? (Galatians 5:19–21)

Mike Mahaffey

The works of the flesh are listed in Galatians 5:19–21 — adultery, fornication, idolatry, hatred, strife, and more. They are not simply bad behaviors to avoid. They are the natural output of faith that has shifted off Christ and Him crucified onto law, self-effort, or religious performance. When that happens, the Holy Spirit steps back, and the flesh fills the space.

There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit. (Romans 8:1)

Paul opens that declaration to believers — people in Christ Jesus. And right inside it is a contrast that runs through everything he writes in Galatians 5. There are two ways to walk. One produces life. The other produces what he calls the works of the flesh.

Before you read the list in Galatians 5:19–21, you need to know what Paul was responding to. The Galatians were not a congregation that had walked away from Christ for the world. They had been led astray by credentialed teachers — Judaizers who came behind Paul’s missionary work and told these Gentile converts that faith in Christ was not sufficient. Circumcision was required. Law-keeping was required. The Cross alone would not do.

Paul calls it what it is in chapter 1. He pronounces anathema — twice — on anyone who preaches another gospel. He repeats it in the next verse for full weight. Then in chapter 5 he asks them directly:

Who did hinder you that ye should not obey the truth? (Galatians 5:7)

Someone got in the road. Someone displaced the Cross with something that sounded scriptural. The works of the flesh are the result.

The Works of the Flesh Are Not a Sin Checklist

Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness, idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies, envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God. (Galatians 5:19–21)

Most people read this passage as a moral catalog — here are the bad things, don’t do them. That reading misses Paul’s entire argument and ironically produces the very thing he’s warning against. When you fight the flesh through behavior management, you are giving the flesh exactly what it feeds on: a rule to perform against.

The works of the flesh are not the disease. They are the symptom. They are the natural output of a soul whose faith has shifted off the Cross onto something else — law, self-effort, religious performance. When that shift happens, the Holy Spirit is grieved and does not have latitude to produce the fruit of the Spirit. The flesh fills that space. And the fruit it produces is exactly what Paul lists here.

This means a born-again believer is capable of producing every single item on this list. Not because they are unsaved, but because faith has drifted.

This is the conflict Paul describes throughout his letter — the tension every believer faces between the flesh and the Spirit. For a deeper look at how the sin nature operates in the life of the born-again believer, see the believer and the sin nature.

Three Groups, One Root

The list in verses 19–21 is not random. Paul moves through three groups — body sins, spiritual sins, relational sins — and every entry in every group is the output of the same displaced faith.

The Body Sins: The Act, the Condition, the Character

Paul opens with adultery, fornication, uncleanness, lasciviousness. These move from the specific outward to the general. Fornication covers all sexual sin outside of marriage. Uncleanness is the state of moral filth that sexual sin produces — a pollution word. Lasciviousness is the posture underneath it all: a shameless, unbridled appetite that no longer feels restraint.

You can see the progression. The act. The condition. The character that forms when the act is repeated without repentance. Each step is a further distance from the inheritance that belongs to the believer in Christ.

The Spiritual Sins: Displaced Allegiance

Idolatry and witchcraft sit together in the list for a reason. Idolatry is placing anything in the position that belongs to God alone. It does not require a carved image. Every time faith is placed in a system, a method, a religious routine rather than in Christ and Him crucified, something has taken God’s place.

Witchcraft — the Greek word is pharmakeia — carries the sense of sorcery and the use of substances to alter the mind and open it to demonic influence. These two sit together because both represent a fundamental rejection of God as the sole source and authority. A believer who drifts into either has not merely sinned morally. They have repositioned their soul toward another kingdom.

The Relational Sins: The Longest Group

Hatred, variance, emulations, wrath, strife, seditions, heresies, envyings, murders. Nine entries. Paul gives more space here than anywhere else on the list. That is not accidental. These are church sins. They live inside congregations. They wear religious clothing.

Variance is discord — the deliberate fracturing of relationships. Emulations is envy with teeth — wanting what another has badly enough to compete destructively. Seditions are factions. Heresies are entrenched party spirits that put a camp above the truth.

Paul places these in the same list as adultery and witchcraft. That should stop every believer who has ever excused strife or division inside the church as something less serious than outright moral sin. It is not. It is flesh. And it comes from the same root: faith that has moved off the Cross.

The Warning in Verse 21

…that they which do such things shall not inherit the kingdom of God. (Galatians 5:21)

That phrase lands like a hammer — and it is directed at the church, not the world. Paul is not warning pagans. He is writing to people who had received the Spirit, who had seen miracles worked among them.

The word inherit is doing specific work here. It is not the same as enter. Inheritance speaks of possession — of walking in the fullness of what belongs to you as a son. A child can be a legitimate heir and still be disinherited in practice by how they live. The Kingdom belongs to the believer in Christ. But the flesh, left unchecked, cuts the believer off from the experience and reward of that inheritance.

They have not necessarily lost their sonship. But they are living like orphans. They are heirs forfeiting what is theirs.

Paul’s warning is not legalism. He is not saying earn your way into the Kingdom. He is saying — look at the fruit. If the works of the flesh are consistently present in a believer’s life, something is wrong with the object of their faith. The list is a diagnostic. Every warning light points back to one question: where is your faith?

The Only Answer

And they that are Christ’s have crucified the flesh with the affections and lusts. (Galatians 5:24)

If we live in the Spirit, let us also walk in the Spirit. (Galatians 5:25)

The answer to every entry on that list is faith placed in Christ and Him crucified. Not behavior modification. Not trying harder against the flesh. When faith is rightly placed in what Christ accomplished at the Cross, the Holy Spirit is given latitude to work. And the fruit He produces — love, joy, peace, longsuffering — crowds out what the flesh would otherwise fill that space with.

The Galatians were led away from that by teachers who added requirements to the Cross. The same displacement happens today — different additions, same result. Anything placed alongside Christ and Him crucified as the object of faith moves the Holy Spirit aside and hands the wheel back to the flesh.

The Cross is not the entry point of salvation that gets left behind. It is the ongoing ground of the believer’s daily walk. The works of the flesh are the evidence that someone has forgotten that.

That is what I hold onto. The moment I try to manage the flesh through effort or religious discipline, I am giving it exactly what it feeds on. The moment faith goes back to Christ and Him crucified, I am where the Holy Spirit can work. That is the only ground that produces anything other than what Paul lists in verses 19 through 21.
