Yet among the mature we do impart wisdom, although it is not a wisdom of this age or of the rulers of this age, who are doomed to pass away. But we impart a secret and hidden wisdom of God, which God decreed before the ages for our glory. None of the rulers of this age understood this, for if they had, they would not have crucified the Lord of glory. (1 Corinthians 2:6-8 ESV)
Through the church the manifold wisdom of God might now be made known to the rulers and authorities in the heavenly places. (Ephesians 3:10 ESV)
My favorite C.S. Lewis quote:
“Do not be deceived, Wormwood. Our cause is never more in danger than when a human, no longer desiring, but still intending, to do our Enemy’s [God’s] will, looks round upon a universe from which every trace of Him seems to have vanished, and asks why he has been forsaken, and still obeys.” ― C.S. Lewis, The Screwtape Letters.
