God is to Noah a faithful Creator; at the dose He accepts the sacrifice, and smelling the savor of Rest, alters the terms of His relationship with the judicially judged earth. The passing away of judgment was gradual, and the dove—the peaceful reign of the Spirit—though it bring token of peace to them in the ark, of whom we have spoken, found no rest till they were all passed.
Note also, the ground was cursed for man's sake; this is arrested on the typical sacrifice, because God finds a savor of rest in that, and, on the recognition of the evil in man, which had led Him to destroy, declares He will no more smite, but the regular order of creation should subsist while the earth remained.
