Romans 7:14-20

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 agree that the law is good.

17As it is, it is no longer I myself who do it, but it is sin living in me.

18For I know that good itself does not dwell in me, that is, in my sinful nature. 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, but the evil I do not want to do—this I keep on doing.

20Now if I do what I do not want to do, it is no longer I who do it, but it is sin living in me that does it.
