James 2:22-26

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] You see that a man (believer) is justified by works and not by faith alone [that is, by acts of obedience a born-again believer reveals his faith]. In the same way, was Rahab the prostitute not justified by works too, when she received the [Hebrew] spies as guests and protected them, and sent them away [to escape] by a different route? [Josh 2:1-21] For just as the [human] body without the spirit is dead, so faith without works [of obedience] is also dead.
