Rom 7:18-25
‘And really, I know of nothing good living in me – in my natural self, that is – for though the will to do what is good is in me, the power to do it is not: the good thing I want to do, I never do; the evil thing which I do not want – that is what I do. But every time I do what I do not want to, then it is not myself acting, but the sin that lives in me. So I find this rule: that for me, where I want to do nothing but good, evil is close at my side.
