“For since by man came death, etc.] The first man, by sin, was the cause of death; of its coming into the world, and upon all men, by which corporeal death is here meant; though the first man also by sin brought a moral death, or a death in sin on all his posterity; and rendered them liable to an eternal death, which is the just wages of sin; but since the apostle is treating of the resurrection of the body, a bodily death seems only intended: by man came also the resurrection of the dead; so God, in his great goodness and infinite wisdom has thought fit, and he has so ordered it, that it should be, that as the first man was the cause of, and brought death into the world, the second man…”
