11For who among men knows the thoughts of a man except the spirit of the man that is in him? In the same way, no one knows the thoughts of God except the Spirit of God.
12Now we have not received the spirit of the world, but the Spirit who comes from God, so that we may understand what has been freely given to us by God.
14But the unbeliever does not welcome what comes from God's Spirit, because it is foolishness to him; he is not able to understand it since it is evaluated spiritually.
