Ya‛aqoḇ (James) 2:14, 17-18

My brothers, what use is it for anyone to say he has belief but does not have works? This belief is unable to save him.

So also belief, if it does not have works, is in itself dead. But someone might say, “You have belief, and I have works.” Show me your belief without your works, and I shall show you my belief by my works.
