James 2:18-23

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].” You believe that God is one; you do well [to believe that]. The demons also believe [that], and shudder and bristle [in awe-filled terror—they have seen His wrath]! [Deut 6:4; 11:13-21; Mark 12:29] But are you willing to recognize, you foolish [spiritually shallow] person, that faith without [good] works is useless? 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]. And 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. [Gen 15:6; 2 Chr 20:7; Is 41:8]
