James 2:21-23

21Was 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]?

22You 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].

23And the Scripture was fulfilled which says, “Abraham believed God, and this [faith] was credited to him [by God] as righteousness and as conformity to His will,” and he was called the friend of God.
