What does the Bible say about the significance of the Passover?

The Passover, established by God in the Old Testament, serves as a profound symbol of deliverance for His people. During the first Passover, God instructed Israel to sacrifice a lamb and mark their doorposts with its blood. This act was a sign of God's mercy, as He would pass over the houses marked by the blood, sparing them from death. This ordinance foreshadows Christ's atoning sacrifice, where His death serves as our substitute, delivering us from the judgment due for our sins. The culmination of the Passover finds its ultimate fulfillment in Christ, who through His death and resurrection provides eternal redemption for His chosen people.
