Romans 7:19

7:18 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.

7:19 For the good that I will to do, I do not do; but the evil I will not to do, that I practice.

7:20 Now if I do what I will not to do, it is no longer I who do it, but sin that dwells in me.
