“But wilt thou know, O vain man, that faith without works is dead?”
King James Version (KJV)
2:20 But art than willing to know - Indeed thou art not: thou wouldest fain be ignorant of it. O empty man - Empty of all goodness. That the faith which is without works is dead - And so is not properly faith, as a dead carcase is not a man.
Jas 2:20 But wilt thou know, O vain man. "I will show by proof that the faith that justifies produces works by the case of Abraham, the great father of the faithful". Faith without works is dead. It has no power to make alive unless it has power over the life.
