1 Corinthians 2

12 We have not received the spirit of the world, but the Spirit who is from God, that we may understand what God has freely given us. 13 And this is what we speak, not in words taught us by human wisdom, but in words taught by the Spirit, expressing spiritual truths in spiritual words.*2:13 Or to spiritual people

14 The natural man does not accept the things that come from the Spirit of God. For they are foolishness to him, and he cannot understand them, because they are spiritually discerned.
