[The Psalms are] a Little Bible, wherein everything contained in the entire Bible is beautifully and briefly comprehended.
Martin LutherWe ought first to know that there are no good works except those which God has commanded, even as there is no sin except that which God has forbidden.
Martin LutherSpare the rod and spoil the child - that is true. But, beside the rod, keep an apple to give him when he has done well.
Martin LutherWhenever the devil harasses you, seek the company of men or drink more, or joke and talk nonsense, or do some other merry thing. Sometimes we must drink more, sport, recreate ourselves, and even sin a little to spite the devil, so that we leave him no place for troubling our consciences with trifles. We are conquered if we try too conscientiously not to sin at all. So when the devil says to you: do not drink, answer him: I will drink, and right freely, just because you tell me not to.
Martin Luther
