The Devil, it is true, is not exactly a doctor who has taken degrees, but he is very learned, very expert for all that. He has not been carrying on his business during thousands of years for nothing.
Martin Luther[Christ's] mission and work it is to help against sin and death, to justify and bring life. He has placed his help in baptism and the Sacrament [i.e., communion/Eucharist/Lord's supper], and incorporated it in the Word and preaching. To our eyes Baptism [capitalized in original] appears to be nothing more than ordinary water, and the Sacrament of Christ's body and blood simple bread and wine, like other bread and wine, and the sermon, hot air from a man's mouth. But we must not trust what our eyes see.
Martin LutherI 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 LutherNo one can believe how powerful prayer is and what it can effect, except those who have learned it by experience. Whenever I have prayed earnestly, I have been heard and have obtained more than I prayed for. God sometimes delays, but He always comes.
Martin LutherBewilderment is the true comprehension. Not to know where you are going is the true knowledge.
Martin LutherIt is the part of a Christian to take care of his own body for the very purpose that, by its soundness and wellbeing, he may be enabled to labour, and to acquire and preserve property, for the aid of those who are in want, that thus the stronger member may serve the weaker member, and we may be children of God, and busy for one another, bearing one another's burdens, and so fulfiling the law of Christ.
