1 Corinthians 2:8-10
2:8 None of the rulers of this age understood it. If they had known it, they would not have crucified the Lord of glory.
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.
