And a dead faith can Not save. God saves us by giving to us a real, alive faith that has works, which will be good by following the moral laws of God.! our faith before salvation by God is a dead faith, which can not save us. But, faith is a principle which is used by all of us in our daily lives. we trust others, but we are not stupid ,to turn our backs on one who will kill us. it must be an informed, alive, faith or we soon die.
