So men come into the sort of personal and social life that Jesus represents. Apart from any theories, they value the life itself--its ideals of character, friendship, service, trust. If honesty allows, they propose to live that life. When a man has gone far enough in Christian experience, so that he comes up to his intellectual difficulties by such a road, he is likely to profit by a consideration of the reasons in favor of faith. He is in the attitude of saying: I have found great living in Christ. No argument for the Christian experience can be quite so convincing as the Christian experience itself. I am bound to have that life if I honestly can, and I will search to see whether there is any insuperable intellectual difficulty in the way of it. II One of the initial perplexities of faith concerns the sort of intellectual assurance which we have a right to expect. In a laboratory of physics, the investigator gathers facts, makes inductions as to their laws, and then verifies his findings. He uses a simplicity of procedure and gains a finality of result that makes all other knowledge seem relatively insecure. To be sure, the scientist may seek long for his truth and make many ineffectual guesses that prove false, but, in the end, he reaches a conclusion so demonstrable that every man of wit enough to investigate the subject must agree that it is so. How the Christian wishes for such certainty concerning God! Before, however, any one surrenders confidence in God, because confessedly the affirmations of religious faith cannot be established by such methods as a physicist employs, there is ample reason for delay. We are certain that heat expands and cold contracts, and we can prove the fact and state its laws. But are we not also sure that it is wrong to lie and right to tell the truth? This conviction about truthfulness at least equals in theoretical certainty and in practical right to determine conduct, our confidence in heat's expanding power. This conviction about truthfulness does actually sway life more than does any single scientific truth that one can name. Let us then set ourselves to prove our moral confidence by such methods as the physical laboratory can supply--with yard sticks, and Troy weight scales, and test tubes, and meters! At once it is evident that if we are to hold only such truth as is amenable to the demonstration of a laboratory, we must bid farewell to every _moral conviction_ that hitherto has influenced our lives. God, banished because the physicist cannot prove him, will have good company in exile!
