'Flesh' in the Bible

It is clear that you are Christ’s letter, produced by us, not written with ink but with the Spirit of the living God—not on stone tablets but on tablets that are hearts of flesh.

For we who live are always given over to death because of Jesus, so that Jesus’ life may also be revealed in our mortal flesh.

Therefore, dear friends, since we have such promises, let us cleanse ourselves from every impurity of the flesh and spirit, completing our sanctification in the fear of God.

For though we live in the body, we do not wage war in an unspiritual way,

especially because of the extraordinary revelations. Therefore, so that I would not exalt myself, a thorn in the flesh was given to me, a messenger of Satan to torment me so I would not exalt myself.
