Why is the concept of eternal salvation important for Christians?

The doctrine of eternal salvation is critical for Christians because it encapsulates the security and assurance of their faith. It is not merely a temporary state; rather, it speaks to the unbreakable bond between the believer and God that endures forever. The assurance of salvation helps to eliminate fear and anxiety concerning one's standing before God, as salvation is rooted in His eternal purpose and not in human works. Furthermore, it stresses that believers must rest in the finished work of Christ, who, as the high priest, secured their salvation through His sacrifice. This doctrine encourages Christians to live in the light of Christ's love and grace, free from the fear of losing their salvation, as it is upheld by God's faithful promises.
