Once D. L. Moody was talking to a man who sold soap which he claimed would do all kinds of remarkable things, including the removing of spots caused by grease. The man was, nevertheless, very perturbed, and at last he told Mr. Moody what his trouble was. "The soap accomplishes all that I assert; but the truth is that it also rots all the clothes which is washes. If I become a Christian, I shall have to give up my business, and I can not bring myself to do that." The evangelist used to say that it was only soap which stood between this man and a Christian life.
