A wise man is he who keeps an even balance between faith and fear: such faith in God's mercy that he says, "If the whole virtuous world were drowned, I with my faith in His mercy should be saved, like Noah in his ark"; and such fear that he says, "If the whole wicked world were saved, I might be taken to task by the wrath of God." Those who do not understand this moral are apt to go astray by seeing the wicked enjoying themselves, and by looking at the suffering of the virtuous.
