Romans 7:15-17

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.
