I have an old mother away down in the Connecticut mountains, and I have been in the habit of going to see her every year for twenty years. Suppose I go there and say, "Mother, you were very kind to me when I was young--you were very good to me; when father died you worked hard for us all to keep us together, and so I have come to see you because it is my duty." I went then only because it was my duty. Then she would say to me, "Well, my son, if you only come to see me because it is your duty, you need not come again." And that is the way with a great many of the servants of God. They work for Him because it is their duty--not for love. Let us abolish this word duty, and feel that it is only a privilege to work for God, and let us try to remember that what is done merely from a sense of duty is not acceptable to God. Moody with Gen. Grant's Army in Richmond. It was my privilege to go to Richmond with Gen. Grant's army. Now just let us picture a scene. There are a thousand poor captives, and they are lawful captives, prisoners in Libby Prison. Talk to some of them that have been there for months and hear them tell their story. I have wept for hours to hear them tell how they suffered, how they could not hear from their homes and their loved ones for long intervals, and how sometimes they would get messages that their loved ones were dying and they could not get home to be with them in their dying hours. Let us, for illustration, picture a scene. One beautiful day in the Spring they are there in the prison. All news has been kept from them. They have not heard what has been going on around Richmond, and I can imagine one says one day, "Ah, boys, listen! I hear a band of music, and it sounds as if they were playing the old battle cry of the Republic. It sounds as if they were playing "The star spangled banner! long may it wave o'er the land of the free and the home of the brave!" And the hearts of the poor fellows begin to leap for joy. "I believe Richmond is taken. I believe they are coming to deliver us," and every man in that prison, is full of joy, and by and by the sound comes nearer and they see it is so. It is the Union army! Next the doors of the prison are unlocked; they fly wide open, and those thousand men are set free. Wasn't that good news to them? Could there have been any better news? They are out of prison, out of bondage, delivered. Christ came to proclaim liberty to the captive. Condemned to be Shot.
