The human heart is like a millstone in a mill: when you put wheat under it, it turns and grinds and bruises the wheat to flour; if you put no wheat, it still grinds on, but then 'tis itself it grinds and wears away.
Martin LutherSinging has nothing to do with the affairs of this world: it is not for the law. Singers are merry, and free from sorrows and cares.
Martin LutherIt is a good thing to let prayer be the first business in the morning and the last in the evening. Guard yourself against such false and deceitful thoughts that keep whispering, "Wait a while. In an hour or so I will pray. I must first finish this or that." Thinking such thoughts we get away from prayer into other things that will hold us and involve us till the prayer of the day comes to naught.
Martin Luther
