Romans 7:17-19

17 However, it is no longer I who do the deed, but the sin [principle] which is at home in me and has possession of me.

18 For I know that nothing good dwells within me, that is, in my flesh. I can will what is right, but I cannot perform it. [I have the intention and urge to do what is right, but no power to carry it out.]

19 For I fail to practice the good deeds I desire to do, but the evil deeds that I do not desire to do are what I am [ever] doing.
