Paul's 1st Letter to the Corinthians.

1:25 Because the foolishness of God is wiser than men, and the weakness of God is stronger than men.
But God has chosen the follish things of the world to put to shame the wise, and God has chosen the weak things of the world to put to shame the things which are mighty;
and the base things of the world and the things which are despised God has chosen, and the things which are not, to bring to nothing the things that are,
that no flesh should glory in His presence.
