Proverbs 26:11 As a dog returneth to his vomit, so a fool returneth to his folly.

Romans 7:23-25 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.

O wretched man that I am! who shall deliver me from the body of this death?

I thank God through Jesus Christ our Lord. So then with the mind I myself serve the law of God; but with the flesh the law of sin.
