Romans 7:15
15 For what I am working out, I do not understand; for I am not practicing what I would like to do, but I am doing the very thing I hate.
Romans 7:18 - 7:19
18 For I know that nothing good dwells in me, that is, in my flesh; for the willing is present in me, but the working out of the good is not. 19 For the good that I want, I do not do, but I practice the very evil that I do not want.
Romans 7:21
21 I find then the principle that in me evil is present—in me who wants to do good.
Romans 7:23
23 but I see a different law in my members, waging war against the law of my mind and making me a captive to the law of sin which is in my members.
