I do not deny that medicine is a gift of God, nor do I refuse to acknowledge science in the skill of many physicians; but, take the best of them, how far are they from perfection? A sound regimen produces excellent effects. When I feel indisposed, by observing a strict diet and going to bed early, I generally manage to get round again, that is, if I can keep my mind tolerably at rest. I have no objection to the doctors acting upon certain theories, but, at the same time, they must not expect us to be the slaves of their fancies.
Martin LutherIt is the most ungodly and dangerous business to abandon the certain and revealed will of God in order to search in to the hidden mysteries of God.
Martin LutherIf he have faith, the believer cannot be restrained. He betrays himself. He breaks out. He confesses and teaches this gospel to the people at the risk of life itself.
