This is from the blog A Word in Season:
“God is not looking for brilliant men, is not depending upon eloquent men, is not shut up to the use of talented men in sending His Gospel out in the world. God is looking for broken men, for men who have judged themselves in the light of the Cross of Christ. When He wants anything done, He takes up men who have come to an end of themselves, and whose trust and confidence is not in themselves but in God.”
--H.A. Ironside
