You, who have grown grey in the great world school, learning its sordid, selfish lessons, grinding away at its daily tasks, adding up your sums of addition, and interest, scanning the money table with eager eyes, practising your skill in profit and loss, and daily writing as your one copy--_make money, and be rich_--to you, I say, come into Christ's school to-day, and see whose teaching is the better: that of the world, or that of the Son of God. There comes to every school a day of breaking up, when the scholars go home. One day a man is missed in the great world school. His place is vacant. The shutters are up at the shop, or office, the servants at the place of business speak in smothered whispers. They miss the sound of the master's voice, the echo of his step upon the stair. He has learnt his last lesson in worldliness, and his schooling is over. The world has broken up, as far as he is concerned, and he has gone home. But where? He knew nothing beyond the world's lessons, he never provided for another home. "What shall it profit a man if he gain the whole world, and lose his own soul?" Briefly, then, let us look at some of the chief lessons which we must learn in the school of Jesus Christ. First, we must learn to hate our old sins. Like David, like S. Peter, like every penitent, when we think of the past we abhor ourselves, and sit down among the ashes of humiliation. Like the Prodigal, we cry, "I am no more worthy to be called Thy son." If you find yourself taking pleasure in the thought of former sin, boasting of your evil deeds, be sure you are yet in your ignorance, you have never learnt the alphabet of Christ's lesson. Next, we must learn to know our own weakness, and our need of a Saviour. The world will not give us that lesson. The world will tell us to make our own way, to trust to ourselves, to our cleverness, and sharpness. In Christ's school we shall be taught our weakness, and shall learn to say, "Lord, save me, I perish."
