1 Corinthians 2:6-8

6 We speak wisdom, however, among those who are full grown; yet a wisdom not of this world, nor of the rulers of this world, who are coming to nothing.  7 But we speak God's wisdom in a mystery, the wisdom that has been hidden, which God foreordained before the worlds for our glory,  8 which none of the rulers of this world has known. For had they known it, they wouldn't have crucified the Lord of glory.
