Romans 7:16-18

New Revised Standard Version, Anglicised Catholic Edition

¹⁶ Now if I do what I do not want, I agree that the law is good. ¹⁷ But in fact it is no longer I that do it, but sin that dwells within 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 do it.
