Romans 4. Abraham was justified by faith, not works and definitely not circumcision. Where there is no law, there is no transgression. Against all hope, Abraham in hope believed, and it was credited to him as righteousness. And “for us also, to whom it shall be imputed, if we believe on him that raised up Jesus our Lord from the dead; Who was delivered for our offences, and was raised again for our justification.”
