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 LutherWorks indeed are good, and God strictly requires them of us, but they do not make us holy.
