1 Corinthians 2:10-13

10God has revealed these to us by the Spirit. For the Spirit searches all things, even the deep things of God.

11For 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.

12Now 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.

13And 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.
