This day shall be for you a memorial day, and you shall keep it as a feast to the Lord; throughout your generations, as a statute forever, you shall keep it as a feast. -Exodus 12:14

Cleanse out the old leaven that you may be a new lump, as you really are unleavened. For Christ, our Passover lamb, has been sacrificed. Let us therefore celebrate the festival, not with the old leaven, the leaven of malice and evil, but with the unleavened bread of sincerity and truth. -1 Corinthians 5:7-8

For followers of Messiah Yeshua (Jesus), Passover commemorates not only the miraculous events described in the book of Exodus, but also our spiritual deliverance from the slavery of sin. The shed blood of the lamb represents the blood of the Messiah. Those who have His blood on the doorposts of their hearts are spared from the second death.
