James 2:13-17

For judgment will be merciless to one who has shown no mercy; but [to the one who has shown mercy] mercy triumphs [victoriously] over judgment. What is the benefit, my fellow believers, if someone claims to have faith but has no [good] works [as evidence]? Can that [kind of] faith save him? [No, a mere claim of faith is not sufficient—genuine faith produces good works.] If a brother or sister is without [adequate] clothing and lacks [enough] food for each day, and one of you says to them, “Go in peace [with my blessing], [keep] warm and feed yourselves,” but he does not give them the necessities for the body, what good does that do? So too, faith, if it does not have works [to back it up], is by itself dead [inoperative and ineffective].
