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.
— Romans 7:14-21
