When I am assailed with heavy tribulations, I rush out among my pigs rather than remain alone by myself. 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. So the human heart, unless it be occupied with some employment, leaves space for the devil, who wriggles himself in and brings with him a whole host of evil thoughts, temptations, and tribulations, which grind out the heart.
Martin LutherAnything that one imagines of God apart from Christ is only useless thinking and vain idolatry.
Martin LutherAn earthly kingdom cannot exist without inequality of persons. Some must be free, some serfs, some rulers, some subjects.
Martin LutherIf I should neglect prayer but a single day, I should lose a great deal of the fire of faith.
Martin LutherThe Jews are the most miserable people on earth. They are plagued everywhere, and scattered about all countries, having no certain resting place. They sit as on a wheelbarrow, without a country, people or government... but they are rightly served, for seeing they refused have Christ and his gospel, instead of freedom they must have servitude.
Martin Luther
