1 Corinthians 2:6-8 NIV

[6] 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. [7] No, we declare God’s wisdom, a mystery that has been hidden and that God destined for our glory before time began. [8] None of the rulers of this age understood it, for if they had, they would not have crucified the Lord of glory.
