1Corinthians 2: 6-9 (NIV)
We do, however, speak a message of wisdom among the mature, but not the wisdom of this age or of the rulers of this age, who are coming to nothing. No, we speak of God’s secret wisdom, a wisdom that has been hidden and that God destined for our glory before time began. None of the rulers of this age understood it for if they had, they would not have crucified the Lord of glory. However, as it is written: No eye has seen, no ear has heard, no mind has conceived what God has prepared for those who love him.
