James 2:17-20

Thus also faith, if it does not have works, is dead by itself. But someone will say, “You have faith and I have works.” Show me your faith apart from your works, and I will show you my faith by my works. You believe that God is one; you do well. Even the demons believe, and shudder! But do you want to know, O foolish person, that faith apart from works is useless?
