ST. PAUL again and again compares himself and the Christians to whom he writes to soldiers, and their lives to warfare. And it was natural that he should do so. Everywhere he went, in those days, he would find Roman soldiers, ruling over men of different races from themselves, and ruling them, on the whole, well. Greeks, Syrians, Jews, Egyptians,—all alike in his days obeyed the Roman soldiers, who had conquered the then known world. And St. Paul and his disciples wished to conquer the world likewise. The Roman soldier had conquered it for Cæsar: St. Paul would conquer it for Christ. The Roman soldier had used bodily force—the persuasion of the sword. St. Paul would use spiritual force—the persuasion of preaching. The Roman soldier wrestled against flesh and blood: St. Paul wrestled against more subtle and dangerous enemies—spiritual enemies, he calls them—who enslaved and destroyed the reason, and conscience, and morals of men. St. Paul and his disciples, I say, had set before themselves no less a task than to conquer the world. Therefore, he says, they must copy the Roman soldier, and put on their armour, as he put on his. He took Cæsar’s armour, and put on Cæsar’s uniform. They must take the armour of God, that they may withstand in the evil day of danger and battle, and having done all,—done their duty manfully as good soldiers,—stand; keep their ranks, and find themselves at the end of the battle not scattered and disorganized, but in firm and compact order, like the Roman soldiers, who, by drill and discipline, had conquered the irregular and confused troops of all other nations. Let me, this morning, explain St. Paul’s words to you, one by one. We shall find them full of lessons—and right wholesome lessons—for in this parable of the armour of God St. Paul sketches what you and I and every man should be. He sketches the character of a good man, a true man, a man after God’s own heart. First, the Christians are to gird their loins—to cover the lower part of their body, which is the most defenceless. That the Roman soldier did with a kilt, much like that which the Highlanders wear now. And that garment was to be Truth. Truthfulness, honesty, that was to be the first defence of a Christian man, instead of being, as too many so-called Christians make it, the very last. Honesty, before all other virtues, was to gird his very loins, was to protect his very vitals. The breastplate, which covered the upper part of the body, was to be righteousness—which we now commonly call, justice. To be a just man, after being first a truthful man, was the Christian’s duty.
