Why is the doctrine of reprobation important for Christians?

The doctrine of reprobation asserts that God has not predestined all to salvation, but has determined some individuals to face eternal judgment due to their rejection of Him. This doctrine is often uncomfortable but is critical to understanding the full scope of God's justice and mercy. In John 8:39-47, Jesus makes a distinction between those who are His sheep and those who are not, indicating that reprobates were never intended for salvation. Acknowledging reprobation compels believers to appreciate their own salvation through grace and serves as a reminder of the seriousness of sin and the necessity for the gospel in reaching the lost.
