James 2:13-17

So you must show mercy to others, or God will not show mercy to you when he judges you. But the person who shows mercy can stand without fear at the judgment. My brothers and sisters, if people say they have faith, but do nothing, their faith is worth nothing. Can faith like that save them? A brother or sister in Christ might need clothes or food. If you say to that person, “God be with you! I hope you stay warm and get plenty to eat,” but you do not give what that person needs, your words are worth nothing. In the same way, faith by itself—that does nothing—is dead.
