Romans 7:17-19

New Catholic Bible

¹⁷ This indicates that it is no longer I who do it, but sin that dwells in me. ¹⁸ For I know that nothing good dwells in me, that is, in my flesh. I have the desire to do what is good, but I cannot do what is good. ¹⁹ For I do not do the good I desire; rather, it is the evil I do not desire that I end up doing.
