IV. And so, lastly, such sympathy should be the parent of a noble, self-sacrificing life. Look at the man in our text. He had the ball at his feet. He had the _entree_ of a court, and the ear of a king. Brilliant prospects were opening before him, but his brethren's sufferings drew him, and with a noble resolution of self-sacrifice, he shut himself out from the former and went into the wilderness. He is one of the Scripture characters that never have had due honour--a hero, a saint, a martyr, a reformer. He did, though in a smaller sphere, the very same thing that the writer of the Epistle to the Hebrews magnified with his splendid eloquence, in reference to the great Lawgiver, 'And chose rather to suffer affliction with the people of God,' and to turn his back upon the dazzlements of a court, than to 'enjoy the pleasures of sin for a season,' whilst his brethren were suffering. Now, dear friends! the letter of the example may be put aside; the spirit of it must be observed. If Christians are to do the work that they can do, and that Christ has put them into this world that they may do, there must be self-sacrifice with it. There is no shirking that obligation, and there is no discharging our duty without it. You and I, in our several ways, are as much under the sway of that absolute law, that 'if a corn of wheat fall into the ground and die, it brings forth fruit,' as ever was Jesus Christ or His Apostles. I have nothing to say about the manner of the sacrifice. It is no part of my business to prescribe to you details of duty. It is my business to insist on the principles which must regulate these, and of these principles in application to Christian service there is none more stringent than--'I will not offer unto my God burnt-offering of that which doth cost me nothing.'
