Because that which the world deems foolish in God is wiser than men's wisdom, and that which it deems feeble in God is mightier than men's might.
For after the world by its wisdom –as God in His wisdom had ordained– had failed to gain the knowledge of God, God was pleased, by the apparent foolishness of the Message which we preach, to save those who accepted it.
We, for Christ's sake, are labeled as »foolish«; you, as Christians, are men of shrewd intelligence. We are mere weaklings: you are strong. You are in high repute: we are outcasts.
For though it is true that He was crucified through weakness, yet He now lives through the power of God. We also are weak, sharing His weakness, but with Him we shall be full of life to deal with you through the power of God.
