Romans 7:16-18 New King James Version (NKJV)

16. If, then, I do what I will not to do, I agree with the law that it is good.

17. But now, it is no longer I who do it, but sin that dwells in me.

18. For I know that in me (that is, in my flesh) nothing good dwells; for to will is present with me, but how to perform what is good I do not find.
