Romans 7:18-20 HCSB
For I know that nothing good lives in me, that is, in my flesh. For the desire to do what is good is with me, but there is no ability to do it. For I do not do the good that I want to do, but I practice the evil that I do not want to do. Now if I do what I do not want, I am no longer the one doing it, but it is the sin that lives in me.
