“For by grace are ye saved through faith it is the gift of God: not of works lest any man should boast ” (Ephesians 2:8)
If you read it correctly it said through faith grace saves you. Grace is a verb which means favor or goodwill. So Gods grace is his favor toward you; it is a favor he is giving you in Jesus who bore our sins in his own body on the cross.
“But God, who is rich in mercy, for his great love herewith he loved us. Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved)” (Ephesians 2:4-5)
