R.A. Torrey, in his short biography of D. L. Moody:
“I believe more promising [ministers] have gone on the rocks through self-sufficiency and self-esteem than through any other cause. I can look back for forty years, or more, and think of many men who are now wrecks or derelicts who at one time the world thought were going to be something great. But they have disappeared entirely from the public view. Why? Because of overestimation of self. Oh, the men and women who have been put aside because they began to think that they were somebody, that they were “IT,” and therefore God was compelled to set them aside.
“Oh, men and women! especially young men and young women, perhaps God is beginning to use you; very likely people are saying: “What a wonderful gift he has as a Bible teacher, what power he has as a preacher, for such a young man!” Listen: get down upon your face before God. I believe here lies one of the most dangerous snares of the devil. When the devil cannot discourage a man, he approaches him on another tack, which he knows is far worse in its results; he puffs him up by whispering in his ear: “You are the leading evangelist of the day. You are the man who will sweep everything before you. You are the coming man. You are the D. L. Moody of the day”; and if you listen to him, he will ruin you. The entire shore of the history of Christian workers is strewn with the wrecks of gallant vessels that were full of promise a few years ago, but these men became puffed up and were driven on the rocks by the wild winds of their own raging self-esteem.”
