The Devil can so completely assume the human form, when he wants to deceive us, that we may well lie with what seems to be a woman, of real flesh and blood, and yet all the while 'tis only the Devil in the shape of a woman. 'Tis the same with women, who may think that a man is in bed with them, yet 'tis only the Devil; and...the result of this connection is oftentimes an imp of darkness, half mortal, half devil.
Martin LutherIt is a tremendously hard thing to pray aright, yea, it is verily the science of all sciences.
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.
Martin Luther
