 "...which things we also speak, not in words taught by human wisdom, but those taught by the Spirit, combining spiritual thoughts with spiritual words. But the natural man," that's a non-believer, "...does not accept the things of the Spirit of God, for they are foolishness to him, and he cannot understand them, but they are spiritually appraised. But he who is spiritual appraises all things, yet he himself is appraised by no man."
