James 2:18-20 New Revised Standard Version (NRSV)
18 But someone will say, “You have faith and I have works.” Show me your faith apart from your works, and I by my works will show you my faith. 19 You believe that God is one; you do well. Even the demons believe—and shudder. 20 Do you want to be shown, you senseless person, that faith apart from works is barren?
