1 Corinthians 2:9-14
2:9 But just as it is written, “Things that no eye has seen, or ear heard, or mind imagined, are the things God has prepared for those who love him.”
2:10 God has revealed these to us by the Spirit. For the Spirit searches all things, even the deep things of God.
2:11 For who among men knows the things of a man except the man’s spirit within him? So too, no one knows the things of God except the Spirit of God.
2:12 Now we have not received the spirit of the world, but the Spirit who is from God, so that we may know the things that are freely given to us by God.
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.
