The Book of James outlines the relationship between faith and works. It was written by James, the brother of Jesus, who became the head of the Jerusalem church. James emphasizes that good works will naturally flow from those filled with the Spirit. He argues that faith without deeds is dead. The book challenges Christians to not just talk about faith, but to demonstrate it through righteous actions. It presents faith as something that should be verified by works, which are the result rather than the cause of salvation.
