The simple ordinary duties which belong to keeping sheep or to getting one's lessons at school, to meeting one's obligations in some modest position in office or store, or in doing one's best in a factory or on a farm, become a kind of dress rehearsal for the larger duties which lie ahead. If a man knows his lines and can take his part effectively upon the narrower stage of action he is in line for promotion to a more important rôle. You will find whole regiments of young fellows who drag along, scamping their work and slighting those opportunities which are right at hand. They are saving up their energies to do something splendidly effective week after next. But week after next never comes to such men. It is always to-day, and to-day in their eyes seems ever small. If those men were already on the quarterdeck as captains of great ocean liners; if they were already bank presidents sitting in handsome offices of their own; if they were already journalists of the first rank writing editorials for metropolitan dailies, they would do what their hands and their minds found to do with their might. But in this day of small things they feel that fidelity and skill would be thrown away. They have mixed up the words of the promise--they think it reads, "You have been unfaithful over a few things, I will make thee ruler over everything." When a man is going up-stairs he must put his foot first on the step which is at the bottom and then take the other steps in order. The same rule holds in the great business of living a man's life and doing a man's work in the world. The young man who was to become king showed courage and high resolve in the face of danger. There came a day when the Israelites and the Philistines were lined up in battle array on the opposite sides of a valley. The Philistines had their champion fighter in the person of a huge fellow named Goliath. His armour weighed one hundred and fifty pounds. His spear was like a weaver's beam. He stood roaring out his defiance against the armies of Israel, "Choose you a man! Let him come down to me and fight. If he kills me, we will be your servants. If I prevail against him then ye shall be our servants." After the manner of the Iliad he stood ready to let the issue of the campaign turn upon the result of a solitary combat between himself and any Israelite they might put up against him. Saul, the king of Israel, had offered to enrich with great wealth the man who would fight that huge Philistine. He had promised to give him the hand of his own daughter, the fair young princess, in marriage, and to make his father's house forever free in Israel. But no Israelite had dared to fight the terrible Goliath.
