What does Luke 22:15 mean?
A week prior, Jesus entered Jerusalem as if He were a king come for His coronation. Since then, the disciples have watched Him establish His authority over the religious leaders (Luke 20). Following Jesus' instructions, Peter and John have prepared the Passover meal and found a room for the core group of Jesus' followers (Luke 22:7–13).The Passover is the annual memorial celebration of the night God told the Israelites they were finally going to be free from their Egyptian slavery (Exodus 12). The disciples are still riding high on the triumphs they have witnessed. Now, Jesus says He has wanted to share this meal with them. They may wonder: is this the Passover meal before the Jews are freed from Roman rule?
They still don't understand that Jesus isn't talking about freedom from Rome. He's talking about rescue from death and sin. The night before the first Passover meal, God struck down the firstborn sons of the Egyptians. Soon, Jesus will be struck down: the Lamb slain for the sins of the world (John 1:29; Revelation 5:6).
Ultimately, Jesus is the fulfillment of the Passover Feast. The Hebrews were protected from God's judgment by the blood of a lamb, freed from slavery in Egypt, and invited into the Promised Land. Jesus is our Passover Lamb (1 Corinthians 5:7; 1 Peter 1:19), by whose blood we can be forgiven (Romans 5:8–11). God frees us from sin and invites us into true life (Ephesians 1:3–14; 2:1–10). It was at this meal that Jesus instituted what is known as the Lord's Supper or Communion. He took part of the Passover ritual and explained how He was instituting the new covenant (Jeremiah 31:31–34) by shedding His blood and giving His body (Luke 22:19–20). When believers today partake in the Lord's Supper, they both proclaim the reality of Jesus' sacrifice and look forward to His return (1 Corinthians 11:25–26). Someday, there will be another feast: the Marriage Supper of the Lamb (Revelation 19:6–10).
This Passover for the disciples began with celebration and ended with mourning. But a time is coming when it will all be joy (Revelation 21—22).
