Romans 7:14-15; Romans 7:18-19

14 For we know that the law is spiritual: but I am carnal, sold under sin.

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.
