The meal known as the Seder (pronounced say-der), means “order,” because the meal and service are done in a prescribed sequence. This sequence is presented in the Haggadah (“telling”), which outlines the steps of the meal as well as the readings for the participants.
Jesus celebrated this meal on the “night he was betrayed” and it is a critical part of the biblical feast of Passover. Passover is one of the three yearly gatherings the Lord has given to His people to celebrate and remember who we are, who God is, what he has done for us, and what He has promised to still complete.
All the Feasts (Easter/Passover, Pentecost/Shavuot, Feast of Booths/Sukkoth) speak of our Messiah, Jesus. The feasts describe and reveal the operation of the Kingdom of God. Hebrews 8:5 says of the Tabernacle in the Wilderness, they are “a copy and shadow of what is in heaven.” So while we may not see clearly into the realm of Heaven, we can see the shadow that it casts on the earth through the Feasts.
Passover is a picture of the redeeming work of Christ. The Apostle Paul refers to Christ as “our Passover” in 1 Corinthians 5. There is an obvious picture of Christ in the Passover lamb. As this lamb was sacrificed to deliver the people from Egypt, so Christ was sacrificed to deliver us from the bondage of sin.
If we have been united with him like this in his death, we will certainly also be united with him in his resurrection. For we know that our old self was crucified with him so that the body of sin might be done away with, that we should no longer be slaves to sin because anyone who has died has been freed from sin.
