How do we know that faith without works is dead?

In James' epistle, he emphasizes that true faith is evidenced by works, stating that faith without works is dead. This means that mere acknowledgment of belief is insufficient; rather, authentic faith manifests itself through actions and behaviors shaped by that faith. James argues that a living faith naturally compels believers to fulfill the royal law of loving their neighbor and to engage in acts of compassion. Therefore, the presence of love and good works in a believer's life is the fruit of genuine faith, distinguishing it from a superficial or false profession of faith.
