Romans 7:19

17 In that case, it is no longer I who do it, but it is sin living in me that does it.

18 I 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.

For I do not do the good I want to do. Instead, I keep on doing the evil I do not want to do.

20 And 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.

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

Do read the surrounding verses too, because the context often says more than a single verse.
