Romans 7:20 in the King James Version
Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me.
Context
19 For the good which I desire, I don’t do; but the evil which I don’t desire, that I practice.
20 But if what I don’t desire, that I do, it is no more I that do it, but sin which dwells in me.
21 I find then the law that, while I desire to do good, evil is present.
