Romans 7:15, 18-19, 21, 23
15 For that which I do I allow not: for what I would, that do I not; but what I hate, that do I.
18 For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not.
19 For the good that I would I do not: but the evil which I would not, that I do.
21 I find then a law, that, when I would do good, evil is present with me.
23 But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members.
