How do we know true faith is evidenced by works?

True faith is not simply an intellectual assent to the existence of God but a transformative trust that results in love and action. James makes it clear that genuine faith is alive and evidenced by works, which are the fruit of such faith. For example, Abraham's willingness to sacrifice Isaac demonstrated his unwavering faith in God's promises (James 2:21-23). Similarly, Rahab's actions in hiding the spies showed that her belief in God influenced her choices, illustrating that faith must produce corresponding deeds of love and service.
