'After The Flesh' in the Bible

There is therefore now no condemnation to them that are in Christ Jesus, who walk not after the flesh but after the spirit.

that the righteousness of the law may be fulfilled in us, who walk not after the flesh but after the spirit.

For they who are after the flesh, mind the things of the flesh; but they who are led by the Spirit, do mind spiritual things.

Therefore, brethren, we are debtors not to the flesh, to live after the flesh:

for if ye live after the flesh, ye shall die; but if by the Spirit ye mortify the deeds of the body, ye shall live.
