Romans 7:18-20
Romans 7:18-20 AMP
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. For the good that I want to do, I do not do, but I practice the very evil that I do not want. But if I am doing the very thing I do not want to do, I am no longer the one doing it [that is, it is not me that acts], but the sin [nature] which lives in me.
