In the collection of religious poems attributed to King David is one psalm wherein he complains of those who reverence not the unchanging God. He shows how a man may with suave and deceitful talk cover over his malign intention. Of such a one he says: "He hath put forth his hands against such as be at peace with him: he hath broken his covenant. The words of his mouth were smoother than butter, but war was in his heart: his words were softer than oil, yet were they drawn swords." Our Master revealed the residence of error when he said, "From within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders, thefts, covetousness, wickedness, deceit, lasciviousness, an evil eye, blasphemy, pride, foolishness: all these evil things come from within, and defile the man." Now if war and its train of evil is to cease it must be deprived of residence and retreat where in concealment it may crouch behind the screen of false and smooth words. Entertained in the heart it grows like the tiger cub kept as a plaything, which in its mature brutality may slay its host. From earliest times it has been said, "All they that take the sword shall perish with the sword." It is not by victories in war, but by victories over war that men will find themselves delivered. Mrs. Eddy has said (Miscellany, p. 281), "War will end when nations are ripe for progress."
