'Flesh' in the Bible

[the good news] regarding His Son, who, as to the flesh [His human nature], was born a descendant of David [to fulfill the covenant promises],

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].

We know that the Law is spiritual, but I am a creature of the flesh [worldly, self-reliant—carnal and unspiritual], sold into slavery to sin [and serving under its control].

For I know that nothing good lives in me, that is, in my flesh [my human nature, my worldliness—my sinful capacity]. For the willingness [to do good] is present in me, but the doing of good is not.

but I see a different law and rule of action in the members of my body [in its appetites and desires], waging war against the law of my mind and subduing me and making me a prisoner of the law of sin which is within my members.

Thanks be to God [for my deliverance] through Jesus Christ our Lord! So then, on the one hand I myself with my mind serve the law of God, but on the other, with my flesh [my human nature, my worldliness, my sinful capacity—I serve] the law of sin.

Therefore there is now no condemnation [no guilty verdict, no punishment] for those who are in Christ Jesus [who believe in Him as personal Lord and Savior].

For what the Law could not do [that is, overcome sin and remove its penalty, its power] being weakened by the flesh [man’s nature without the Holy Spirit], God did: He sent His own Son in the likeness of sinful man as an offering for sin. And He condemned sin in the flesh [subdued it and overcame it in the person of His own Son],

so that the [righteous and just] requirement of the Law might be fulfilled in us who do not live our lives in the ways of the flesh [guided by worldliness and our sinful nature], but [live our lives] in the ways of the Spirit [guided by His power].

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,

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].

So then, brothers and sisters, we have an obligation, but not to our flesh [our human nature, our worldliness, our sinful capacity], to live according to the [impulses of the] flesh [our nature without the Holy Spirit]—

for if you are living according to the [impulses of the] flesh, you are going to die. But if [you are living] by the [power of the Holy] Spirit you are habitually putting to death the sinful deeds of the body, you will [really] live forever.

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.
