James 2:17-20

17So too, faith, if it does not have works [to back it up], is by itself dead [inoperative and ineffective].

18But 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].”

19You 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]!

20But are you willing to recognize, you foolish [spiritually shallow] person, that faith without [good] works is useless?
