1 Corinthians 2:13-16

2:13 And we speak about these things, not with words taught us by human wisdom, but with those taught by the Spirit, explaining spiritual things to spiritual people. 2:14 The unbeliever does not receive the things of the Spirit of God, for they are foolishness to him. And he cannot understand them, because they are spiritually discerned. 2:15 The one who is spiritual discerns all things, yet he himself is understood by no one. 2:16 For who has known the mind of the Lord, so as to advise him? But we have the mind of Christ.
