It was in 1873, in Dublin that D.L. Moody heard British evangelist Henry Varley utter those life changing words: “The world has yet to see what God can do with and for and through and in a man who is fully and wholly consecrated to Him.” It was after an all-night prayer meeting in Dublin, at the home of Henry Bewley. Varley did not even remember making the statement when Moody reminded him of it a year later. “As I crossed the wide Atlantic,” Moody said, “the boards of the deck…were engraved with them, and when I reached Chicago, the very paving stones seemed marked with them.”
The result: Moody decided he was involved in too many ministries to be effective and therefore began to concentrate on evangelism.

“God has yet to show what He can do through the life of a man who is wholly yielded to Him.” This expression drove Dawson Trotman to unintentionally start a worldwide ministry that focuses on producing reproducers.
This is an excerpt from an Amazon book review of Trotman’s biography, but I have heard others attribute it to him as well – most notably Robert Rayburn, president of Covenant Theological Seminary in St. Louis (1956-1976), who had worked with Trotman.
