Origen Against Celsus V6

Now the human wisdom is that which is termed by us the wisdom of the world, which is foolishness with God; whereas the divine –being different from the human, because it is divine –comes, through the grace of God who bestows it, to those who have evinced their capacity for receiving it, and especially to those who, from knowing the difference between either kind of wisdom, say, in their prayers to God.
