"One night when [Dwight L.] Moody was going home, it suddenly occurred to him that he had not spoken to a single person that day about accepting Christ. A day lost, he thought to himself. But as he walked up the street he saw a man by a lamppost. He promptly walked up to the man and asked, 'Are you a Christian?'
"Moody did not find soul-winning easy. In fact, even other Christians often criticized him for having zeal without knowledge. Others called him 'Crazy Moody.' Once when he spoke to a perfect stranger about Christ, the man said, 'That is none of your business...If you were not a sort of preacher, I would knock you into the gutter for your impertinence.' [A gutter ran along the street carrying waste and rain water--it was very filthy.]
"The next day, a businessman friend sent for Moody. The businessman told Moody that the stranger he had spoken to was a friend of his. 'Moody, you've got zeal without knowledgge. You insulted a friend of mine on the street last night. You went up to him, a perfect stranger, and asked him if he were a Christian.'
"Moody went out of his friend's office almost brokenhearted. For sometime he worred about this. Then late one night a man pounded on the door of his home. It was the stranger he had supposedly insulted. The stranger said, 'Mr. Moody, I have not had a good night's sleep since that night you spoke to me under the lamp-post, and I have come around at this unearthly hour of the night for you to tell me what I have to do to be saved.' "
