Romans 7:12-21

12So then, the law is holy, and the commandment is holy, righteous, and good.

13Did that which is good, then, become death to me? Certainly not! But in order that sin might be exposed as sin, it produced death in me through what was good, so that through the commandment sin might become utterly sinful.

14We know that the law is spiritual; but I am unspiritual, sold as a slave to sin. 15I do not understand what I do. For what I want to do, I do not do. But what I hate, I do. 16And if I do what I do not want to do, I admit that the law is good. 17In that case, it is no longer I who do it, but it is sin living in me that does it.

18I know that nothing good lives in me, that is, in my flesh; for I have the desire to do what is good, but I cannot carry it out. 19For I do not do the good I want to do. Instead, I keep on doing the evil I do not want to do. 20And if I do what I do not want, it is no longer I who do it, but it is sin living in me that does it.

21So this is the principle I have discovered: When I want to do good, evil is right there with me.
