What does the Bible say about saving a soul from death?

In James 5:19-20, we are taught that if any among us strays from the truth and is converted back, they save a soul from death. This process symbolizes not only the restoration of the individual to true faith but also highlights the gravity of error in understanding faith itself. True faith is not merely intellectual assent to doctrines; it is an active, living faith that produces repentance and transformation in a believer's life. Thus, when one addresses a fellow believer who has erred, seeking to bring them back to the true faith, they play a pivotal role in their spiritual restoration and protection from the eternal consequences of sin.
