Why is the doctrine of eternal punishment important for Christians?

Eternal punishment is a sobering reality emphasized in Matthew 25:46, where Jesus states that the unrighteous will go away into everlasting punishment. This doctrine serves several crucial purposes for Christians. Firstly, it highlights the gravity of sin and the holiness of God, who must judge sin righteously. Secondly, it reflects the severe consequences of rejecting the Savior, impacting how believers view their mission to share the Gospel. Understanding eternal punishment prompts a sense of urgency in evangelism, as there are real eternal stakes involved. Ultimately, this doctrine cultivates a deeper appreciation for the grace and mercy shown to the elect, as they are saved from such a fate by Christ's sacrificial atonement.
