"You that preach Christ in the streets, go on preaching Him. I saw a man preaching the other day with no creature but one dog to listen to him, and I really thought that he might as well have gone home. But I met with a story yesterday, which I know to be true, and it showed me that I was making a mistake. There was a woman who for years had been in such dreadful despair that she would not even hear the gospel. She came to be very ill, and she said to one that called upon her, "You sent a man to preach under my window three months ago, and I got a blessing." "No," the friend said, "I never sent anybody to preach under your window." "Oh," she said, "I think you did, for he came and preached, and my maid said that there was nobody listening to him. I did not want to hear him; and I lay down in bed; but the man shouted so that I was obliged to hear him; and I thank God I did, for I heard the gospel, and I found Christ. Did you not send him?" "No," said the good man, "I did not." "Well," she said, "then God did. There was nobody in the street listening to him; but I heard the gospel, and I got out of my despair, and I found the Savior, and I am prepared to die."
