But there are reasons for doubting the correctness of this view. Right makes God's will, surely enough; but is it certain that the side whose cause is just will win the war, simply because it is the side of right and of God? Ultimately, we may be sure, right must prevail, for wrong is not the sort of thing that can permanently succeed; it contains within itself the germs of its own ultimate destruction. But nothing in history can be surer than that this ultimate judgment upon evil does not necessarily involve the defeat of all unjustified military undertakings. The side with the greater moral justification has not always won its battles, nor even its wars. It is not enough to have justice on our side; we must use our might on the side of right. Right has to be worked for, and sometimes it has to be fought for. That is the kind of world that--not unfortunately for our development, probably--we are living in. And the fighting is no sham battle. Its issue is not predetermined. It is being decided while the fighting is going on. Moreover, with reference to prayer as a military factor, it is only fair to note that in the present war many sincere and believing prayers for victory have been offered on both sides. It is not intended to deny that religion of a certain sort is an important military factor; sincere and believing prayer for a cause that is regarded as sacred and just undoubtedly helps morale, both in the army and throughout the nation. But it is a factor which in this war has operated on both sides. Man has the capacity for misusing not only physical, but even spiritual forces. But, on the other hand, when prayer and religious faith encourage an easy-going attitude, and are thus made to some extent a substitute for effort, such prayer and faith cannot but prove a serious military hindrance, no matter how just the cause may be that they are designed to support. They may even conceivably make enough of a difference on the wrong side to lead to the defeat of righteousness.
