What does the Bible teach about the significance of the lamb in the Passover?

In the Passover narrative, the lamb plays a pivotal role as it embodies the attributes required for sacrifice: it must be without blemish, male, and in its prime. These qualities symbolize Jesus Christ, who is perfect and sinless, thus qualifying Him to bear the sins of humanity. The requirement that the lamb be slain at a specific time further reflects God's sovereign plan for salvation, with Christ being sacrificed at God's appointed time. This type not only reflects the necessity of substitutionary atonement but also emphasizes the grace of God in providing the means for salvation. The lamb's blood, which protected the Israelites from death, correlates with the cleansing power of Christ’s blood for believers, securing their eternal life.
