13 Which things also we speak, not in words which man’s wisdom teaches, but which the Holy Spirit teaches, comparing spiritual things with spiritual things.
14 Now the natural man doesn’t receive the things of God’s Spirit, for they are foolishness to him, and he can’t know them, because they are spiritually discerned.
15 But he who is spiritual discerns all things, and he himself is judged by no one.
16 “For who has known the mind of the Lord, that he should instruct him?” But we have Christ’s mind.
