How often it is that men with physical strength do not serve Christ! They are like a ship full-manned and full-rigged, capable of vast tonnage, able to endure all stress of weather, yet swinging idly at the docks, when these men ought to be crossing and recrossing the great ocean of human suffering and sin with God's supplies of mercy. How often it is that physical strength is used in doing positive damage, or in luxurious ease, when, with sleeves rolled up and bronzed bosom, fearless of the shafts of opposition, it ought to be laying hold with all its might, and tugging away to lift up this sunken wreck of a world!
It is a most shameful fact that much of the business of the Church and of the world must be done by those comparatively invalid. Richard Baxter, by reason of his diseases, all his days sitting in the door of the tomb, yet writing more than a hundred volumes, and sending out an influence for God that will endure as long as the Saints' Everlasting Rest. Edward Payson, never knowing a well day, yet how he preached, and how he wrote, helping thousands of dying souls like himself to swim in a sea of glory! And Robert McCheyne, a walking skeleton, yet you know what he did in Dundee, and how he shook Scotland with zeal for God. Philip Doddridge, advised by his friends, because of his ill ness, not to enter the ministry, yet you know what he did for the "rise and progress of religion" in the Church and in the world.
Wilberforce told by his doc tors that he could not live a fortnight, yet at that very time entering upon philanthropic enterprises that demanded the greatest endurance and persistence. Robert Hall, suffering excruciations, so that often in his pulpit while preaching he would stop and lie down on a sofa, then getting up again to preach about heaven until the glories of the celestial city dropped on the multitude, doing more work, perhaps, than almost any well man in his day.
Oh, how often it is that men with great physical endurance are not as great in moral and spiritual stature! While there are achievements for those who are bent all their days with sick ness achievements of patience, achievements of Christian en durance I call upon men of health today, men of muscle, men of nerve, men of physical power, to devote themselves to the Lord. Giants in body, you ought to be giants in soul.
