1 Corinthians 2:9-10
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.
1 Corinthians 2:14
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.
