To preach faith (It has been said) is to prevent good works; but if a man should possess the strength of all men united, or even of all creatures this sole obligation of living in faith would be a task too great for him ever to accomplish. If I say to a sick man: 'Be well, and thou shalt have the use of thy limbs,' will anyone say that I forbid him to use his limbs? Must not health precede labor? It is the same when we preach faith: it should go before works, in order that the works themselves should exist."
