10 Now God has revealed these things to us by the Spirit, for the Spirit searches everything, u even the depths of God. v 11 For who among men knows the thoughts w of a man except the spirit x of the man that is in him? In the same way, no one knows y the thoughts z of God except the Spirit of God. 12 Now 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. 13 We also speak these things, not in words a taught by human wisdom, but in those taught by the Spirit, explaining spiritual things to spiritual people. b 14 But the unbeliever c 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 d spiritually.
