It is hard to see how a great man can be an atheist. Without the sustaining influence of faith in a divine power we could have little faith in ourselves. We need to feel that behind us is intelligence and love. Doubters do not achieve; skeptics do not contribute; cynics do not create. Faith is the great motive power, and no man realizes his full possibilities unless he has the deep conviction that life is eternally important, and that his work, well done, is a part of an unending plan.
