Romans 7:17-19

Amplified Bible

¹⁷ 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. ¹⁸ For I know that nothing good lives in me, that is, in my flesh [my human nature, my worldliness—my sinful capacity]. For the willingness [to do good] is present in me, but the doing of good is not. ¹⁹ For the good that I want to do, I do not do, but I practice the very evil that I do not want.
