If minimizing the importance of religious faith is unintelligent, so is avoiding some sort of decision about religious faith impossible. Most of those into whose hands these studies fall will grant readily faith's incalculable importance. Some, however, will be not helped but plunged into deeper trouble by their consent. For they feel themselves unable to decide about a matter which they acknowledge to be the most important in the world. Asked whether they believe in God, they would reply with one of Victor Hugo's characters, "Yes--No--Sometimes." They grant that to be steadily assured of God would be an invaluable boon, but for themselves, how can they balance the opposing arguments and find their way to confidence? All our studies are intended for the help of such, but at the beginning one urgent truth may well be plainly put. However undecided they may appear, men cannot altogether avoid decision on the main matters of religion. Life will not let them. For while the mind may hold itself suspended between alternatives, the adventure of life goes on, and men inevitably tend to live either as though the Christian God were real or as though he were not. Some questions allow a complete postponement of decision. As to which of several theories about the Northern Lights may be true, a man can hold his judgment in entire suspense. Life does not require from him any action that depends on what he thinks of the Aurora Borealis; and whether a man think one thing or another, no conceivable change would be the consequence in anything he said or did. But there is another kind of question, where, however much the mind may waver between opinions and may resolve on indecision, life itself compels decision. A man cannot really be agnostic and neutral on a question like the moral law of sexual purity, for, by an irrevocable necessity, he has to act one way or another. He may stop thinking, but he cannot stop living. With tremendous urgency the adventure of life insistently goes on, and it never pauses for any man to make up his mind on any question. Therefore while a man may theoretically suspend his judgment as to the requirements of the moral law, his life will be a loud, convincing advertisement to all who know him that he has vitally decided. _A man can avoid making up his mind, but he cannot avoid making up his life._
