I think I may have crafted the perfect theological prompt for the generative artificial intelligence chatbot known as ChatGPT. Using this prompt, I then asked it to explain the relationship, if any, between Galatians 5:17 and Romans 7:15-23. The following was the explanation that it gave me.
Mind blown.

The War Within: Galatians 5:17 and Romans 7:15–23 in Theological Perspective
The Christian life is one of conflict, not an external war against flesh and blood but an internal battle between the Spirit and the flesh. Every believer, no matter how mature in faith, experiences this struggle. Two key passages in Paul's writings, Galatians 5:17 and Romans 7:15–23, describe this reality. While they address different aspects of the believer's sanctification, they share a common theme: the war within the heart of the regenerate elect.
Many misunderstand this battle, tending to assume that true Christians should be free from such a struggle, or, conversely, that struggling with sin means that one is still unregenerate. However, a careful, theologically rigorous reading of these passages reveals that this war is not a sign of spiritual death but of spiritual life. In what follows, I will show that these two passages describe the same fundamental conflict viewed from different angles, and that this battle is part of God's eternal decree to sanctify his people for his glory.
Galatians 5:17 -- The Spirit vs. the Flesh
In Galatians 5:17, Paul writes:
For the flesh has desires that are opposed to the Spirit, and the Spirit has desires that are opposed to the flesh, for these are in opposition to each other, so that you do not do what you want.
Here, Paul describes the battle as one between the flesh (σάρξ) and the Spirit (Πνεῦμα). The flesh does not merely refer to the body but to the remnants of the believer's fallen nature, which still exerts influence even after regeneration. The Spirit, on the other hand, refers to the indwelling presence of God who produces holiness in the believer's life.
Paul's point is that these two forces are at war. The result is that the believer does not always do what he desires in accordance with the Spirit's leading. This tension between the desires of the flesh and the desires of the Spirit characterizes the Christian life, making sanctification a process of continual struggle and growth rather than immediate perfection.
This passage underscores the doctrine of progressive sanctification, the idea that while believers are already justified and made new in Christ they must still grow in holiness. The battle against the flesh will not be fully won until glorification.
Romans 7:15-23 -- The Law of Sin vs. the Law of God
In Romans 7:15–23, Paul provides a more introspective and personal description of this same struggle:
For I do not understand what I am doing. For I do not do what I want—instead, I do what I hate (v. 15).
This passage is deeply existential, as Paul describes his frustration with his inability to fully obey God. He expands on this struggle in verses 16-23, where he contrasts two "laws" at work within him:
- The law of God, which his inner being delights in (v. 22).
- The law of sin, which dwells in his members and wages war against his mind (v. 23).
This language echoes Galatians 5:17 but with a legal dimension. Paul speaks of a war within his very being: though he desires to obey God, sin still clings to him.
This passage is often debated, with some arguing that Paul is speaking about his pre-conversion state while others insist that he is describing the experience of a regenerate believer. However, the Reformed, monergistic, and confessional reading understands this as the struggle of a believer. Several reasons support this:
- Paul speaks of his inner man delighting in God's law (Rom 7:22), which is not true of an unregenerate person (cf. Rom 8:7-8).
- The struggle Paul describes assumes an awareness of sin that only the regenerate would have. The unregenerate do not war against sin; they are enslaved to it and seek after it.
- This passage aligns with Galatians 5:17, which explicitly applies to believers.
Thus, Romans 7 provides a first-person, experiential account of the very struggle Paul describes in Galatians 5:17, namely, the war between the flesh and the Spirit, or in this case the law of sin and the law of God.
How These Two Passages Relate
Although these passages describe the same fundamental struggle, they approach it from different perspectives:
Galatians 5:17 | Romans 7:15-23 |
| Focuses on the war between Spirit and flesh. | Focuses on the war between God's law and sin. |
| Addresses the corporate experience of believers. | Provides a personal, introspective account. |
| Emphasizes walking by the Spirit to resist the flesh. | Emphasizes the frustration of sin's lingering presence. |
| Offers a direct exhortation: "Walk by the Spirit and you will not gratify the desires of the flesh." | Ends with a cry for deliverance: "Who will rescue me from this body of death?" |
While the passage in Galatians presents the solution (walking in the Spirit), the one in Romans climaxes in desperation, leading into the glorious answer in Romans 8:1:[/B]
There is therefore now no condemnation for those who are in Christ Jesus.
The victory over the flesh and sin is secured in Christ, and the Spirit, given in the new covenant, ensures that believers will ultimately triumph.
A Reformed and Theocentric Perspective
A proper understanding of this struggle must be rooted in God's eternal decree. The battle between flesh and Spirit is not a mere consequence of the fall but part of God's sovereign plan to magnify the glory of his salvific grace. God decreed that his elect would not only be justified but also sanctified and this through struggle. This is not an accident of history but a purposeful, divine design.
In a covenantal framework, this conflict occurs within the context of God's promises. The Spirit's work in the elect believer is guaranteed by the new covenant, ensuring that victory is certain even though the battle is fierce. Christ, the true covenant-keeper, has already secured the triumph over sin. The believer, united to Christ, fights not FOR victory but FROM victory.
This theocentric view guards against both despair (as if we could lose the battle) and presumption (as if the battle does not exist). It compels the believer to trust not in his own strength but in the Spirit's power.
A Battle That Ends in Victory
Galatians 5:17 and Romans 7:15–23 describe the same reality, namely, the believer's war against sin. But this war, far from indicating defeat, is evidence of spiritual life. Only the regenerate experience this struggle—peace with God produces enmity with sin. The unregenerate experience a very different struggle—peace with sin produces enmity with God.
This war will not end until glorification, when the believer is made fully like Christ. Until then, we fight—not alone, but by the Spirit's power. The Christian life is cruciform, shaped by the reality that, just as Christ warred against sin on the cross, so we also war against sin in our flesh.
Yet, the battle is not in vain. For as Paul declares in Romans 8:37:
No, in all these things we have complete victory through him who loved us.
The war rages on, but the outcome is already decided. Victory belongs to Christ—and to all who are in him.

, our faith is not worthless, and we do not remain dead in sin. Praise God!
