_Second, there is the courage of resistance_.--This is the chief form courage should take in the young. They are surrounded on every side by strong temptations--temptations addressed to their lower nature, to vanity, to indolence, to scepticism, to impurity, to drunkenness. There is many a young man beset by temptation who has in reality to fight far harder if he will maintain his integrity than any soldier belonging to an army making its way through an enemy's country. He does not know when an ambush may be sprung upon him, or from what side the attack may come. In an old tower on the Continent they show you, graven again and again on the stones of one of the dungeons, the word _Resist_. It is said that a Protestant woman was kept in that hideous place for forty years, and during all that time her employment was in graving with a piece of iron, for anyone who might come after her, that word. It is a word that needs to be engraven on every young man's and young woman's heart. It represents the highest form of courage which to them is possible--the power to say "No" to every form of temptation. _Third, there is the courage of endurance_.--This is really the noblest form of courage. There is no excitement in it; nothing to be won by it. It is simply to bear without flinching. In the buried city of Herculaneum, near Vesuvius, now uncovered, after the guide has shown the visitor the wonders of the place he takes him to the gate and points out the stone box where were found, buried in ashes, the rusted remains of the helmet and cuirass of the Roman sentinel. When the black cloud rose from the mountain, and the hot ashes fell around him, and the people rushed out at the gate, he stood there immovable, because it was his duty, and died in his place, suffocated by the sulphury air. It was a grand instance of courage, but it is seen again and again equalled in common life. In men and women stricken down by fell disease; in those on whom adverse circumstances close like the walls of an iron chamber; in people for whom there was no possible escape, who could only bear, but who stood up firm and erect in their weakness, whose cross, instead of crushing them to the earth, seemed only to lift them up. We are told that Robert Hall, the great preacher, suffered much from disease. He was forced often to throw himself down and writhe on the ground in paroxysms of pain. From these he would rise with a smile, saying, "I suffered much, but I did not cry out, did I? did I cry out?" These are the chief forms of moral courage in ordinary life. We have now to point out what are the sources of such courage.
