James 2:18-19

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]
