1 Corinthians 2:12-16

12But we received, not the spirit of the world, but the spirit which is from God; that we might know the things that were freely given to us of God. 13Which things also we speak, not in words which man’s wisdom teacheth, but which the Spirit teacheth; combining spiritual things with spiritual words. 14Now the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him; and he cannot know them, because they are spiritually judged. 15But he that is spiritual judgeth all things, and he himself is judged of no man. 16For who hath known the mind of the Lord, that he should instruct him? But we have the mind of Christ.
