Why is Jesus' death and resurrection important for Christians?

The significance of Jesus' death and resurrection cannot be overstated; they form the cornerstone of Christian faith. Jesus died as a substitute for His people, fulfilling divine justice by bearing the penalty for sin. Through His resurrection, believers are assured of their own future resurrection and eternal life. This act of love was predestined and demonstrates God's mercy and grace toward sinners. Without His sacrificial death and victorious resurrection, there would be no hope for redemption or reconciliation with God, which is essential for all who believe.
