D.L. Moody once called on a leading citizen in Chicago to persuade him to accept Christ. They were seated in the man's parlor. It was winter and coal was burning in the fireplace. The man objected that he could be just as good a Christian outside the church as in it. Moody said nothing, but stepped to the fireplace, took the tongs, picked a blazing coal from the fire and set it off by itself. In silence the two watched it smolder and go out. "I see," said the man.
