Prayer is a force as real as terrestrial gravity. As a physician, I have seen men lifted out of sickness by the power of prayer. It is the only power in the world that overcomes the laws of nature.

Prayer, the basic exercise of the spirit, must be actively practiced in our private lives. The neglected soul of the human being must be made strong enough to assert itself once more. For if the power of prayer is again released and used in the lives of common men and women; if the spirit declares its aims clearly and boldly, there is yet hope that our prayers for a better world will be answered.
