Romans 7:18-20 King James Version (KJV)
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.
20 Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me.
Romans 7:23 King James Version (KJV)
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.
