Why is the concept of Christ dying for the church important for Christians?

Understanding that Christ died for the church and not for everyone universally is foundational for grasping the assurance of salvation. This doctrine affirms that God's grace is not arbitrary but purposeful, emphasizing His sovereign choice in salvation. The certainty that Christ's blood was shed intentionally for His people provides profound comfort and security to believers, knowing that their salvation is guaranteed by God's eternal decree. It eliminates any notion of chance or luck in redemption, pointing instead to a loving and intentional God who actively pursued His chosen ones.
