For sin, taking occasion by the commandment, deceived me, and by it slew me.
Paul emphasized that the Law was not to blame for his actions. It was indwelling sin that incited him to do what the Law prohibited. Sin tricked him into thinking that the forbidden fruit wasn’t so bad after all, that it would bring happiness, and that he could get away from it. It suggested that God was withholding pleasures from him that were for his good. Thus sin killed him in the sense that it spelled death to his best hopes of deserving or earning salvation.
