Wilberforce was told by his doctors 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 sickness--achievements of patience, achievements of Christian endurance--I call upon men of health to-day, 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. II. Behold also, in the story of my text, illustration of the fact of the damage that strength can do if it be misguided. It seems to me that this man spent a great deal of his time in doing evil--this Samson of my text. To pay a bet which he had lost by guessing of his riddle he robs and kills thirty people. He was not only gigantic in strength, but gigantic in mischief, and a type of those men in all ages of the world who, powerful in body or mind, or any faculty of social position or wealth, have used their strength for iniquitous purposes. It is not the small, weak men of the day who do the damage. These small men who go swearing and loafing about your stores and shops and banking-houses, assailing Christ and the Bible and the Church--they do not do the damage. They have no influence. They are vermin that you crush with your foot. But it is the giants of the day, the misguided giants, giants in physical power, or giants in mental acumen, or giants in social position, or giants in wealth, who do the damage. The men with sharp pens that stab religion and throw their poison all through our literature; the men who use the power of wealth to sanction iniquity, and bribe justice, and make truth and honor bow to their golden scepter. Misguided giants--look out for them! In the middle and the latter part of the last century no doubt there were thousands of men in Paris and Edinburgh and London who hated God and blasphemed the name of the Almighty; but they did but little mischief--they were small men, insignificant men. Yet there were giants in those days.
