This, also, brings rest to the human heart, a rest to be found nowhere else. I am in a position to speak with some confidence and positiveness on this point; for, like the man who uttered the text, I have tried life in all its phases. I have had all the kinds of pleasure, and I have tested them to the bottom. I have found out all there is in them. For forty years I gave myself to seeking and enjoying worldly pleasure, and I ought to know what it can do for a human soul. But I have another advantage, too; I have tried the doctrine of my text. I have surrendered myself, my life, my prospects, my all, to God, and live only to keep His commandments and to please Him. My mind has been renewed, transformed, my life entirely turned around. I have passed through the struggle and the sacrifice that were involved in becoming a Christian, and I have been passing through those that belong to the life of a Christian. But you may say I speak thus because it is a novelty to me. No, sir; it is no longer a novelty. I have been trying it now for ten years--surely a long enough time to know pretty well how it compares with the old life; and my testimony, from forty years' experience of the old life and ten years of the new life, is that of the writer of my text, "Fear God and keep His commandments: for this is the whole duty of man." HEBREWS XII: 1, 2. "1. Wherefore, seeing we also are compassed about with so great a cloud of witnesses, let us lay aside every weight, and the sin which doth so easily beset us, and let us run with patience the race that is set before us. "2. Looking unto Jesus, the Author and Finisher of our faith; who for the joy that was set before Him endured the cross, despising the shame, and is set down at the right hand of the throne of God."
