James 2:17-22

So faith by itself, if it has no works, is dead.
But someone will say, ‘You have faith and I have works.’ Show me your faith without works, and I by my works will show you my faith. You believe that God is one; you do well. Even the demons believe—and shudder. Do you want to be shown, you senseless person, that faith without works is barren? Was not our ancestor Abraham justified by works when he offered his son Isaac on the altar? You see that faith was active along with his works, and faith was brought to completion by the works.
