Why are Galatians 5:20 acts sinful?
Why are the acts listed in Galatians 5:20 considered sinful?

Canonical Context

“Now the works of the flesh are obvious: sexual immorality, impurity, debauchery, idolatry, sorcery, hatred, strife, jealousy, fits of rage, selfish ambition, dissensions, factions, envy, drunkenness, orgies, and the like. I warn you, as I did before, that those who practice such things will not inherit the kingdom of God” (Galatians 5:19-21).

Verse 20 sits between two antithetical catalogues: “the works of the flesh” (vv. 19-21) and “the fruit of the Spirit” (vv. 22-23). Paul frames the list as self-evident rebellion against God’s moral order and sets it in stark contrast to the Spirit-produced virtues. The passage is therefore not a random enumeration but a cohesive indictment of behaviors that oppose both the character of Yahweh and the redemptive work of Christ.


Theological Foundation: Holiness of God vs. Works of the Flesh

1 Peter 1:16 quotes Leviticus: “Be holy, because I am holy” . Any attitude or behavior that clashes with God’s holiness is sin. Each item in Galatians 5:20 either substitutes another object for God, violates love of neighbor, or fractures the unity of the redeemed community—thereby transgressing both tablets of the Decalogue (Exodus 20; Deuteronomy 5). The definition of sin is “lawlessness” (1 John 3:4); the acts in verse 20 exemplify that lawlessness.


Old Testament Roots

Paul’s list echoes prohibitions scattered through Torah. Idolatry and sorcery appear in the first two commandments and in Deuteronomy 18; relational sins mirror prohibitions in Leviticus 19. The continuity underscores that Scripture is a unified revelation: the moral law reflects God’s immutable character.


Christological Contrast

Christ embodies perfect obedience (Hebrews 4:15). By His death and resurrection He liberates believers from the dominion of the flesh (Romans 6:6-11). Therefore, persisting in the works of the flesh denies the practical lordship of the risen Christ and quenches the Spirit (1 Thessalonians 5:19).


Anthropological and Behavioral Dynamics

Behavioral science confirms that practices like unresolved anger, envy, and factionalism increase anxiety, cardiovascular risk, and social breakdown, aligning with the biblical claim that sin is destructive. These acts distort the imago Dei, hindering human flourishing and community cohesion—outcomes measurable in empirical research on aggression and group conflict.


Eschatological Warning

Paul’s refrain “will not inherit the kingdom of God” (v. 21) is covenantal and eschatological. Persistent, unrepentant indulgence signals a heart not regenerated (1 John 3:9). The warning is gracious: it calls for self-examination in light of final judgment (2 Corinthians 13:5).


Pastoral and Missional Application

The antidote is walking by the Spirit (Galatians 5:16). Regeneration births new desires; sanctification cultivates the fruit of the Spirit (vv. 22-23). Practically, believers confess, repent, and pursue reconciliation (Matthew 5:23-24). Corporate worship, Scripture intake, prayer, and accountability leverage God-ordained means for transformation.


Conclusion

The acts in Galatians 5:20 are deemed sinful because they contradict God’s holy character, violate love of God and neighbor, fracture the unity purchased by Christ’s blood, and demonstrate allegiance to the flesh rather than the Spirit. Scripture presents them not merely as moral infractions but as existential threats to inheritance in the kingdom, urging every reader toward the grace that both forgives and transforms through Jesus Christ our risen Lord.
