James 2:14-19

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]. 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]
