Romans 7:15-18

For I do not understand my own actions [I am baffled and bewildered by them]. I do not practice what I want to do, but I am doing the very thing I hate [and yielding to my human nature, my worldliness—my sinful capacity]. Now if I habitually do what I do not want to do, [that means] I agree with the Law, confessing that it is good (morally excellent). So now [if that is the case, then] it is no longer I who do it [the disobedient thing which I despise], but the sin [nature] which lives in me. For I know that nothing good lives in me, that is, in my flesh [my human nature, my worldliness—my sinful capacity]. For the willingness [to do good] is present in me, but the doing of good is not.
