'Flesh' in the Bible

So then, was I indecisive or capricious when I was [originally] planning this? Or the things I plan, do I plan in a self-serving way like a worldly man, ready to say, “Yes, yes” and “No, no” [at the same time]?

For we who live are constantly [experiencing the threat of] being handed over to death for Jesus’ sake, so that the [resurrection] life of Jesus also may be evidenced in our mortal body [which is subject to death].

So from now on we regard no one from a human point of view [according to worldly standards and values]. Though we have known Christ from a human point of view, now we no longer know Him in this way.

I ask that when I do come I will not be driven to the boldness that I intend to show toward those few who regard us as if we walked according to the flesh [like men without the Spirit].

For though we walk in the flesh [as mortal men], we are not carrying on our [spiritual] warfare according to the flesh and using the weapons of man.

The weapons of our warfare are not physical [weapons of flesh and blood]. Our weapons are divinely powerful for the destruction of fortresses.

Since many boast [of worldly things and brag] about human accomplishments, I will boast too.

Because of the surpassing greatness and extraordinary nature of the revelations [which I received from God], for this reason, to keep me from thinking of myself as important, a thorn in the flesh was given to me, a messenger of Satan, to torment and harass me—to keep me from exalting myself!
