How do we know that Christ's suffering was for our salvation?

Christ's suffering is central to understanding salvation in sovereign grace theology. His agony on the cross fulfilled the prophecy of Psalm 22, where He experienced the weight of separation from God, ultimately so that we might not endure eternal separation. His unparalleled anguish underscores the depth of His love and the seriousness of sin. Romans 8:32 reminds us that God did not spare His own Son but delivered Him up for us all. This act of sacrificial love fulfills the requirement of God's justice, allowing believers to be reconciled with God without the barrier of sin. Thus, Christ's suffering is the basis for our salvation, demonstrating that through His sacrifice, we are granted access to God and the promise of eternal life.
