Behold! The Lamb Of God

The Passover lamb and its blood were foreshadowings of Christ's sacrifice as the Lamb of God; just as the Israelites had to apply the lamb's blood to be saved from the final plague in Egypt, we must apply Christ's blood through baptism to be saved from sin; we commemorate Christ's sacrifice through the Lord's Supper just as the Passover feast commemorated the Israelites' deliverance from slavery in Egypt.
