Does “Flesh” (σάρξ) in the Bible Refer to a Sinful Nature or a Mindset? A Closer Look at Romans 13:14

When discussing the concept of “flesh” (σάρξ) in the New Testament, interpretations often equate it with the “sinful nature,” a pervasive condition inherited from Adam that drives humanity toward sin. In fact a popular translation keeps translating it as sinful nature. This is confusing as the Bible clearly says in Romans 6 and other verses that we have been crucified with Christ, and our old self has died with Him.

We have discussed in this blog that flesh is the old mindset, but then we find verses that say these.

Romans 13:14: “But put on the Lord Jesus Christ, and make no provision for the flesh, to gratify its desires.”

Galatians 5:16: “But I say, walk by the Spirit, and you will not gratify the desires of the flesh.”

Galatians 5:24: “And those who belong to Christ Jesus have crucified the flesh with its passions and desires.”

Ephesians 2:3: “Among them we too all formerly lived in the lusts of our flesh, indulging the desires of the flesh and of the mind, and were by nature children of wrath, even as the rest.”

1 Peter 2:11: “Beloved, I urge you as sojourners and exiles to abstain from the passions of the flesh, which wage war against your soul.”

So you see that the flesh has desires, passions and it even says in these verses “its desires”. So, people who say that we still have sinful nature and we need to crucify the flesh go “I told you so!”

For example, in Romans 13:14, the English translation states:

“But put on the Lord Jesus Christ, and do not make provision for the flesh, to gratify its desires.”

This phrasing gives the impression that “flesh” is sinful nature—that possesses desires and drives behavior. However, a deeper examination of the Greek grammar and context reveals that this interpretation may oversimplify the meaning of σάρξ and impose theological ideas not inherent in the text. Let’s explore whether “flesh” is best understood as a sinful nature or as a mindset or condition of living independently of God.

What Does the Greek Grammar Say?

In Romans 13:14, the key phrase is:

“τῆς σαρκὸς πρόνοιαν μὴ ποιεῖσθε, εἰς ἐπιθυμίας”

Translated: “Do not make provision for the flesh, towards its desires.”

The English translation “to gratify its desires” supplies the possessive pronoun “its,” implying that the “flesh” has intrinsic desires of its own. However, the Greek grammar does not include a possessive pronoun. Without the possessive pronoun, the verse could be understood as:

• “Do not make provision for the flesh, toward desires” or
• “Do not make provision for the flesh, resulting in desires.”

This suggests that desires are associated with the flesh, but the flesh is not necessarily the body of sin, but rather a mindset that is full of these mindsets and these push towards desires.

“For those who live according to the flesh (σάρξ) set their minds on the things of the flesh, but those who live according to the Spirit set their minds on the things of the Spirit” (Romans 8:5).

Here, σάρξ is clearly a mindset or orientation toward worldly or sinful things, contrasted with life in the Spirit.\

Similarly for other verses too, the verse implies that desires and passions originate from the flesh, but it does not personify the flesh as actively “having” desires.

Conclusion

While the English translation of Romans 13:14 (“to gratify its desires”) can give the impression that “flesh” is an autonomous sinful nature, the Greek grammar and broader biblical usage suggest otherwise. The flesh is best understood as a mindset or way of living apart from God—one that believers are called to reject by putting on Christ and walking in the Spirit. The emphasis is not on flesh as an independent, internal force but on our choices to either indulge or resist its influence. This understanding clarifies that victory over the flesh comes not from striving in our strength but from embracing our new identity in Christ.
