Listen, then, to this sweet, silent voice calling us to go and do likewise. Lord, what wilt thou have me to do? It is to a life of toil, not of indolence, we are called. The fields are white already, unto harvest. Who will bear the sheaves away? Who among our young men in this congregation will take the place of Elder Knowles? Can you be engaged in a grander or nobler work? He that winneth souls is wise. Is there any purer pleasure in this world than the joy that is experienced in the heart when souls are converted to God? Oh, young men, deeply meditate on that precious passage. He that converteth a sinner from the error of his ways, doth save a soul from death, and doth hide a multitude of sins. Are not the opportunities great in this city for doing good? Is not the wickedness great? Are not souls perishing around you for lack of knowledge? Resolve, from this day, that, God helping you, you will dedicate all your powers of heart, soul, and strength to the blessed service of Christ. You are not your own. You have been saved, that you may save others by pulling them out of the fire. Haste then, haste to the rescue. Souls may perish, and go down to hell, while you are deliberating. I remember, years ago, while coming into New York Harbor, we lost a very promising young man overboard. The life-boat was launched, and the life-buoy was cut adrift. But through some delay, the young man perished. What a tremendous disappointment those parents experienced as they stepped on board the frigate at the Brooklyn Navy Yard, and learned that their darling boy had found a watery grave. I never think of the above sad occurrence but I am forcibly reminded that through the delays and sad neglect of Christian parents and Sabbath-school teachers, many young persons perish, and I inquire, Who is responsible for their destruction? Many ask the question that Cain impudently put to the Lord, "Am I my brother's keeper?" We can be guilty of other men's sins. This is a mysterious fact, but it is nevertheless true. If you are an idler in the Master's vineyard, you are, to a certain extent, responsible. Oh, that the Holy Spirit would show us our duty to our fellow-men. Our departed brother realized this truth. Just look at a man seventy-five years old, occupied every Lord's Day teaching a large class of youth in the Sabbath-school. But you must remember that for six days in the week he nobly toiled as a printer, from eight in the morning until six at night. And he seldom missed the prayer-meeting, or other gatherings of the Church. He was, indeed, a worker that needeth not to be ashamed. In the absence of the pastor he frequently led the prayer-meeting, and his expositions of the chapter read as the lesson of the night were very scriptural, cheering, and full of encouragement. He was familiarly acquainted with the Word of God, and his prayers were earnest, solemn, and to the point, because his soul was surcharged with Divine truth.
