Romans 7:18-21

AKJV(i) 18 For I know that in me (that is, in my flesh,) dwells 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. 20 Now if I do that I would not, it is no more I that do it, but sin that dwells in me. 21 I find then a law, that, when I would do good, evil is present with me.
