" They turn the heart away much more strongly than adversity and want do, as he says in his song (Deut. 32:15): “Having become swollen, fat, and thick, he rebelled”; and (Prov. 1:32): “The prosperity of the foolish destroys them”; as is said also in the German proverb: “You need strong legs to hold up under good days.” For man endures evil more easily than good, as the poet says: “Luxury has invaded as a deadlier foe.”2 "
