1 Corinthians 2:7-10

No, the wisdom we speak of is the mystery of God—his plan that was previously hidden, even though he made it for our ultimate glory before the world began. But the rulers of this world have not understood it; if they had, they would not have crucified our glorious Lord. That is what the Scriptures mean when they say, “No eye has seen, no ear has heard, and no mind has imagined what God has prepared for those who love him.” But it was to us that God revealed these things by his Spirit. For his Spirit searches out everything and shows us God’s deep secrets.
