The explanation we find is this: that for a human life in the present stage of existence the opportunity of struggle for moral ends--it may be ends of no great dignity, yet really moral, and, as the race advances, religious--this makes life worth living and brings to every one the means of true and lasting gain. "Where ignorant armies clash by night" there may be in the opposing ranks the most various notions of religion and of what is morally good. The histories of the nations that meet in shock of battle determine largely what hopes and aims guide individual lives. But to the thousands who do valiantly this conflict belongs to the vital struggle in which some idea of the morally good or of religious duty directs and animates the soul. For hearth and home, for wife and children, for chief and comrades, for Jehovah or Baal, men fight, and around these names there cluster thoughts the sacredest possible to the age, dignifying life and war and death. There are better kinds of struggle than that which is acted on the bloody field; yet struggle of one kind or other there must be. It is the law of existence for the barbarian, for the Hebrew, for the Christian. Ever there is a necessity for pressing towards the mark, striving to reach and enter the gate of higher life. No land flowing with milk and honey to be peaceably inherited and enjoyed rewards the generation which has fought its way through the desert. No placid possession of cities and vineyards rounds off the life of Canaanitish tribe. The gains of endurance are reaped, only to be sown again in labour and tears for a further harvest. Here on earth this is the plan of God for men; and when another life crowns the long effort of this world of change, may it not be with fresh calls to more glorious duty and achievement?
But the golden cord of Divine Providence has more than one strand; and while the conflicts of life are appointed for the discipline of men and nations in moral vigour and in fidelity to such religious ideas as they possess, the purer and stronger faith always giving more power to those who exercise it, there is also in the course of life, and especially in the suffering war entails, a reference to the sins of men. Warfare is a sad necessity. Itself often a crime, it issues the judgment of God against folly and crime. Now Israel, now the Canaanite becomes a hammer of Jehovah. One people has been true to its best, and by that faithfulness it gains the victory. Another has been false, cruel, treacherous, and the hands of the fighters grow weak, their swords lose edge, their chariot-wheels roll heavily, they are swept away by the avenging tide. Or the sincere, the good are overcome; the weak who are in the right sink before the wicked who are strong. Yet the moral triumph is always gained. Even in defeat and death there is victory for the faithful.
In these wars of Israel we find many a story of judgment as well as a constant proving of the worth of man's religion and virtue. Neither was Israel always in the right, nor had those races which Israel overcame always a title to the power they held and the land they occupied. Jehovah was a stern arbiter among the combatants. When His own people failed in the courage and humility of faith, they were chastised. On the other hand, there were tyrants and tyrannous races, freebooters and banditti, pagan hordes steeped in uncleanness who had to be judged and punished. Where we cannot trace the reason of what appears mere waste of life or wanton cruelty, there lie behind, in the ken of the All-seeing, the need and perfect vindication of all He suffered to be done in the ebb and flow of battle, amid the riot of war.
