Romans 8:3

For what the law — Of Moses. Could not do, in that it was weak through the flesh — Incapable of conquering our evil nature. If it could, God needed not to have sent his own Son in the likeness of sinful flesh — We with our sinful flesh were devoted to death. But God sending his own Son, in the likeness of that flesh, though pure from sin, condemned that sin which was in our flesh; gave sentence, that sin should be destroyed, and the believer wholly delivered from it.
