When stripped of vagaries and purged of excesses, we must all believe in it - on the evidence. It is not a new discovery, but the re-discovery of a neglected truth that the mind or will is the controller of the body, that divine power is exercised in conformity with natural laws and through the operation of human forces. It is so true, that it is able to put on the market many quack remedies and to give a certain currency to false systems of religion and morals. But the abuse of the truth does not make it untrue. There can be no healing without faith.
Every physician knows that.
He knows that, in certain circumstances, the confidence his presence inspires is as beneficial to the patient as any medicine he prescribes. There is a great deal of sickness that need not be, if there were faith enough to cast it out. For if we admit that the belief that they are ailing can make people actually ill, we must also admit that the prayer of faith can help the sick and restore those who have a desire to be well. There is really no limit to the achievements of faith. All things are possible to him that believes.
