“But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned.”*
“For they that are after the flesh do mind the things of the flesh; but they that are after the Spirit the things of the Spirit.
“For to be carnally minded is death; but to be spiritually minded is life and peace.
“Because the carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be.
“So then they that are in the flesh cannot please God.”**
