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 LutherNo man should be alone when he opposes Satan. The Church and the ministry of the Word were instituted for this purpose, that hands may be joined together and one may help another.
Martin LutherAntichrist is the pope and the Turk [Muslim] together. A beast full of life must have a body and soul. The spirit or soul of Antichrist is the pope, his flesh or body the Turk.
