Romans 7:18 (KJV): "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."

Ephesians 2:8-9 (KJV): "For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast."
