James 2:18, 21-22

But someone may say, “You [claim to] have faith and I have [good] works; show me your [alleged] faith without the works [if you can], and I will show you my faith by my works [that is, by what I do].”

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].
