1 Corinthians 2:6-10

However, I speak a wisdom to those who are mature. But this wisdom is not from this world or from the rulers of this world, who are losing their power. I speak God’s secret wisdom, which he has kept hidden. Before the world began, God planned this wisdom for our glory. None of the rulers of this world understood it. If they had, they would not have crucified the Lord of glory. But as it is written in the Scriptures: “No one has ever seen this, and no one has ever heard about it. No one has ever imagined what God has prepared for those who love him.” But God has shown us these things through the Spirit. The Spirit searches out all things, even the deep secrets of God.
