Romans 7:17-19

New Revised Standard Version, Anglicised Catholic Edition

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. ¹⁹ For I do not do the good I want, but the evil I do not want is what I do.
