James 2:20-23

20But wilt thou know, O vain man, that faith without works is dead? 21Was not Abraham our father justified by works, when he had offered Isaac his son upon the altar? 22Seest thou how faith wrought with his works, and by works was faith made perfect?1 23And the scripture was fulfilled which saith, Abraham believed God, and it was imputed to him for righteousness: and he was called the Friend of God.
