he(Paul) shows that sin did not commence with the law of Moses, but was in the world until, or before, that law; therefore that law of Moses is not the only rule of life, for there was a rule, and that rule was transgressed, before the law was given. It likewise intimates that we cannot be justified by our obedience to the law of Moses, any more than we were condemned by and for our disobedience to it. Sin was in the world before the law; witness Cain's murder, the apostasy of the old world, the wickedness of Sodom. His inference hence is, Therefore there was a law; for sin is not imputed where there is no law. Original sin is a want of conformity to, and actual sin is a transgression of, the law of God: therefore all were under some law. His proof of it is, Death reigned from Adam to Moses, Rom_5:14. It is certain that death could not have reigned if sin had not set up the throne for him. This proves that sin was in the world before the law, and original sin, for death reigned over those that had not sinned any actual sin, that had not sinned after the similitude of Adam's transgression, never sinned in their own persons as Adam did - which is to be understood of infants, that were never guilty of actual sin, and yet died, because Adam's sin was imputed to them. This reign of death seems especially to refer to those violent and extraordinary judgments which were long before Moses, as the deluge and the destruction of Sodom, which involved infants. It is a great proof of original sin that little children, who were never guilty of any actual transgression, are yet liable to very terrible diseases, casualties, and deaths, which could by no means be reconciled with the justice and righteousness of God if they were not chargeable with guilt.
