Immediately after the matzah, we drink the third cup of redemption. Jesus, during the Last Supper specifically took the 3rd cup after supper, the cup of redemption through which God said “I will take you for My people and I will be your God”.
Luke 22, verse 20 says “In the same way, he (Jesus) took the cup after they had eaten.” Jesus infused the cup with new meaning when he said “This cup which is poured out for you is the New Covenant in MY blood.” This fulfilled Jeremiah Ch. 31 vs. 33 when the prophet spoke for God saying, “I will put my law within them, and on their heart I will write it. I will be their God and they shall be my people.” This speaks of our being Born Again.
The Christian communion, takes two elements from the Passover Service: The unleavened bread and the cup of redemption, the cup after supper. Communion is an abbreviated version of Passover using these two elements of the Passover meal.
The fourth cup is taken at the end of the Passover Service . It is the cup of Praise…Christ did not drink this cup….He will drink it in Heaven with us to celebrate our home coming at the marriage super of the Lamb.
