Romans 4:15 - Clarke's commentary and critical notes on the Bible

Because the law worketh wrath: for where no law is, there is no transgression. Because the law worketh wrath - For law νομος, any law, or rule of duty. No law makes provision for the exercise of mercy, for it worketh wrath, οργην, punishment, for the disobedient. Law necessarily subjects the transgressor to punishment; for where no law is - where no rule of duty is enacted and acknowledged, there is no transgression; and where there is no transgression there can be no punishment, for there is no law to enforce it. But the Jews have a law, which they have broken; and now they are exposed to the penal sanctions of that law; and, if the promises of pardon without the works of the law, do not extend to them, they must be finally miserable, because they have all broken the law, and the law exacts punishment. This was a home stroke, and the argument is unanswerable.
