What does James mean by 'faith without works is dead'?

This statement emphasizes that while faith is foundational to salvation, it must produce fruit—namely good works—as evidence of its authenticity. Dead faith lacks the transformative power to bring about a change in behavior. Therefore, if one's profession of faith does not lead to a life marked by obedience and good deeds, it raises doubts about the truth of that faith. James teaches that living faith, empowered by the Spirit of God, will express itself in a life characterized by godly actions and attitudes.
