How do we know the significance of the Passover is true?

For 1,500 years, the Passover served as a reminder of God's mercy in passing over the sins of His people through the application of the lamb's blood. As stated in the sermon, God promised to provide a Lamb, which ultimately foreshadowed Jesus Christ. The Bible affirms this in passages like John 1:29, where John the Baptist identifies Christ as the Lamb of God. The fulfillment of the Passover in Christ's sacrifice demonstrates the transformative aspect of the covenant of grace and assures believers of God’s merciful provision for redemption. The historical observance of the Passover connects to the New Testament revelation of Jesus' atoning work, reinforcing the significance of His sacrifice for salvation.
