What does the Bible say about Jesus' sacrifice on the cross?

In the New Testament, particularly in John 19, the account of Jesus' crucifixion highlights the significance of His sacrifice as the fulfillment of God's purpose for redemption. Jesus cried out 'It is finished,' indicating that He accomplished the work the Father sent Him to do. This included perfect obedience to the law, serving as the perfect sacrificial Lamb without blemish, as required in Leviticus. The author of Hebrews reinforces this by explaining that through His blood, Jesus entered into the holy place, securing eternal redemption for His people (Hebrews 9:12).
