'Have Faith' in the Bible

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.]

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].”
