So did something good bring death to me? Absolutely not! But sin caused my death through something good so that sin would be exposed as sin. That way sin would become even more thoroughly sinful through the commandment. We know that the Law is spiritual, but I’m made of flesh and blood, and I’m sold as a slave to sin. I don’t know what I’m doing, because I don’t do what I want to do. Instead, I do the thing that I hate. But if I’m doing the thing that I don’t want to do, I’m agreeing that the Law is right. But now I’m not the one doing it anymore. Instead, it’s sin that lives in me. I know that good doesn’t live in me—that is, in my body. The desire to do good is inside of me, but I can’t do it. I don’t do the good that I want to do, but I do the evil that I don’t want to do. But if I do the very thing that I don’t want to do, then I’m not the one doing it anymore. Instead, it is sin that lives in me that is doing it.
So I find that, as a rule, when I want to do what is good, evil is right there with me. I gladly agree with the Law on the inside, but I see a different law at work in my body. It wages a war against the law of my mind and takes me prisoner with the law of sin that is in my body. I’m a miserable human being. Who will deliver me from this dead corpse? Thank God through Jesus Christ our Lord! So then I’m a slave to God’s Law in my mind, but I’m a slave to sin’s law in my body.
