Why must the boy leave his brilliant prospects and put himself under the bullets and shells in the trenches? Why must the mother let him go? It is only a shallow thinker, I believe, who can remain long under the impression that the "categorical imperative," as Kant called it, or, as we might say, this insistent, imperious voice, can be produced by any process of evolution at all. It speaks like the voice of a person; it argues like a person; it refuses to be silenced like a person. And the argument is more than justified that, if there is a Person who made the world and still carries it on, it is more than probably the same Person who is speaking to us in conscience. The fact that by His warnings and encouragements He clearly cares so much for righteousness is a standing witness that the Person who swings the stars is more than a strong and clever devil, which the author of the material universe alone might conceivably be, but a Person with a passion for goodness. Otherwise, as Dr. Chalmers said, He would not have placed in the breast of every one of His children, of every one of His created beings, a reclaiming witness against Himself. We have come, then, a good way out of sceptical vagueness when we have arrived at a Person of appalling power, and yet of equally appalling righteousness, who is thundering His will through every conscience in the world, as though standing in the midst of the universe and striking at the same time four hundred million gongs; not leaving it for someone else to do, but doing it Himself. But, alas! we are still far from loving Him, for indeed He is still far from being lovable. Love is the only thing which we cannot command at will and which we cannot give at will; and the world would be in a sorry plight so far as loving GOD is concerned, if nothing more had been done by GOD than this.
