9 Bible Verses about Flesh As The Sinful Nature

And those who belong to Christ Jesus have crucified the sinful nature together with its passions and appetites.

Now the practices of the sinful nature are clearly evident: they are sexual immorality, impurity, sensuality (total irresponsibility, lack of self-control), idolatry, sorcery, hostility, strife, jealousy, fits of anger, disputes, dissensions, factions [that promote heresies], envy, drunkenness, riotous behavior, and other things like these. I warn you beforehand, just as I did previously, that those who practice such things will not inherit the kingdom of God.

Among these [unbelievers] we all once lived in the passions of our flesh [our behavior governed by the sinful self], indulging the desires of human nature [without the Holy Spirit] and [the impulses] of the [sinful] mind. We were, by nature, children [under the sentence] of [God’s] wrath, just like the rest [of mankind].

But clothe yourselves with the Lord Jesus Christ, and make no provision for [nor even think about gratifying] the flesh in regard to its improper desires.

Those who want to make a good impression in public [before the Jews] try to compel you to be circumcised, just so they will escape being persecuted for [faithfulness to] the cross of Christ. For even the circumcised [Jews] themselves do not [really] keep the Law, but they want to have you circumcised so that they may boast in your flesh [that is, in the fact that they convinced you to be circumcised].

For the sinful nature has its desire which is opposed to the Spirit, and the [desire of the] Spirit opposes the sinful nature; for these [two, the sinful nature and the Spirit] are in direct opposition to each other [continually in conflict], so that you [as believers] do not [always] do whatever [good things] you want to do.

For those who are living according to the flesh set their minds on the things of the flesh [which gratify the body], but those who are living according to the Spirit, [set their minds on] the things of the Spirit [His will and purpose]. Now the mind of the flesh is death [both now and forever—because it pursues sin]; but the mind of the Spirit is life and peace [the spiritual well-being that comes from walking with God—both now and forever]; the mind of the flesh [with its sinful pursuits] is actively hostile to God. It does not submit itself to God’s law, since it cannot, read more.
and those who are in the flesh [living a life that caters to sinful appetites and impulses] cannot please God. However, you are not [living] in the flesh [controlled by the sinful nature] but in the Spirit, if in fact the Spirit of God lives in you [directing and guiding you]. But if anyone does not have the Spirit of Christ, he does not belong to Him [and is not a child of God].

For the one who sows to his flesh [his sinful capacity, his worldliness, his disgraceful impulses] will reap from the flesh ruin and destruction, but the one who sows to the Spirit will from the Spirit reap eternal life.

When we were living in the flesh [trapped by sin], the sinful passions, which were awakened by [that which] the Law [identifies as sin], were at work in our body to bear fruit for death [since the willingness to sin led to death and separation from God].
