“Because the law worketh wrath: for where no law is, there is no transgression.”
King James Version (KJV)
4:15 Because the law - Considered apart from that grace, which though it was in fact mingled with it, yet is no part of the legal dispensation, is so difficult, and we so weak and sinful, that, instead of bringing us a blessing, it only worketh wrath; it becomes to us an occasion of wrath, and exposes us to punishment as transgressors. Where there is no law in force, there can be no transgression of it.
Ro 4:15 Because the law worketh wrath. The law threatens punishment to all who break its enactments, and since none keep it perfectly, it works punishment for all. For where no law is, [there is] no trangression. Whereas, if no law had been given, there could be "no transgression" of its demands.
