James 2:21-22
James 2:21-22 AMP
Was our father Abraham not [shown to be] justified by works [of obedience which expressed his faith] when he offered Isaac his son on the altar [as a sacrifice to God]? [Gen 22:1-14] You see that [his] faith was working together with his works, and as a result of the works, his faith was completed [reaching its maturity when he expressed his faith through obedience].
