Joshua's career has in it a great stumbling-block to many people, in that merciless destruction of the Canaanite sinners, which can only be vindicated by remembering, first, that it was a divine appointment, and that God has the right to punish; and, second, that those old days were under a different law, or at least a less manifestly developed law of loving-kindness and mercy than, thank God! we live in. But whilst we look with wonder on these awful scenes of destruction, may there not lie in them the lesson for us that antagonism and righteous wrath against evil in all its forms is the duty of the soldiers of Christ? There are many causes to-day which to further and fight for is the bounden duty of every Christian, and to further and fight for which will tax all the courage that any of us can muster. Remember that the leadership of Christ is no mere pretty metaphor, but a solemn fact, which brings with it the soldier's responsibilities. When our Centurion says to us, 'Come!' we must come. When He says to us, 'Go!' we must go. When He says to us 'Do this!' we must do it, though heart and flesh should shrink and fail. Unhesitating obedience to His authoritative command will deliver us from many of the miseries of self-will; and brave effort at Christ's side is as much the privilege as the duty of His servants and soldiers. II. So note, secondly, the Leader through death to life. Peter, in the sermon which is found in the third chapter of this Book of the Acts, has his mind and heart filled with the astounding fact of the Resurrection and Ascension of Jesus Christ, and in the same breath as he gives forth the paradoxical indictment of the Jewish sin, 'You have killed the Prince of Life'--the Leader of Life--he also says, 'And God hath raised Him from the dead.' So that the connection seems to point to the risen and glorified life into which Christ Himself passed, and by passing became capable of imparting it to others. The same idea is here as in Paul's other metaphor: 'Now is Christ risen from the dead, and become the first-fruits of them that slept'--the first sheaf of the harvest, which was carried into the Temple and consecrated to God, and was the pledge and prophecy of the reaping in due season of all the miles of golden grain that waved in the autumn sunshine. 'So,' says Peter, 'He is the Leader of Life, who Himself has passed through the darkness, for "you killed Him"; mystery of mysteries as it is that you should have been able to do it, deeper mystery still that you should have been willing to do it, deepest mystery of all that you did it not when you did it, but that "He became dead and is alive for evermore." You killed the Prince of Life, and God raised Him from the dead.'
