2:9 But just as it is written, “Things that no eye has seen, or ear heard, or mind imagined, 1 are the things God has prepared for those who love him.” 2 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.
1 Corinthians 2:16
2:16For who has known the mind of the Lord, so as to advise him? 3 But we have the mind of Christ.
