What does the Bible say about the significance of Christ's sacrifice?

The significance of Christ's sacrifice lies in its completion of the Old Testament sacrificial system. When Jesus declared 'It is finished' in John 19:30, He affirmed that His sacrifice was a perfect, once-for-all atonement for sin. No longer was there a need for the continual sacrifices of animals, as His death satisfied the justice of God and provided a means for sinners to be reconciled. This completion marked a profound transition in redemptive history, affirming that through Christ, the way to God was opened for all who believe.
