The Bible includes two main salvation stories, and they're deeply related to each other. The story of the exodus is the Old Testament salvation story, and, of course, the story of the cross and resurrection of Jesus is the New Testament salvation story. Just a hint of how they're related: when Jesus is transfigured on the mountain with Moses and Elijah in Luke 9, they discuss with Jesus his coming "departure" (Greek: exodus) in Jerusalem (Luke 9:31).

The exodus story builds for eleven chapters, beginning with Israel's enslavement, the call of Moses, the plagues, and, finally, the death of Egypt's firstborn sons. It's a dramatic story, and the actual exodus itself is soaked in ceremony and drama too.

On the eve of Israel's departure, God institutes a memorial meal that will celebrate this moment of salvation for generations to come. The Passover, with its slaughtered lamb, becomes a new type of memorial on the eve of Jesus' crucifixion.

Strangely, God does not lead the Israelites away from Egypt and toward the promised land by the most likely and natural route. Instead of heading due east, God leads them south, along the Red Sea. When Pharaoh, unsurprisingly, changes his mind and begins to chase them with his army, the Israelites know that they're stuck, almost literally, between the devil (Pharaoh's army) and the deep blue (Red) sea.

Realizing their hopeless situation, the Israelites cry out in fear and frustration to Moses, "Was it because there were no graves in Egypt that you brought us to the desert to die?" (14:11). Seeing the dust of approaching chariots, Moses finds the faith for his most shining moment. "Do not be afraid. . . . The Lord will fight for you!" Then Moses raises his rod over the roiling sea, and God parts the waters so the Israelites can enter on dry ground.

It's a jubilant story of deliverance, but it's also gruesome. Pharaoh's armies plunge into the sea after the Israelites, the water returns, and all the horses and their riders drown in the writhing waters. In the morning, their bodies are strewn along the shore. Miriam and the women dance and sing in praise to God: "I will sing to the Lord, for he is highly exalted. Both horse and driver he has hurled into the sea" (Ex. 15:21)

This Old Testament story of salvation prefigures our own salvation in Jesus Christ. We were enslaved to sin and death. Jesus came to be our Savior, but things looked hopeless when he was condemned and nailed to a cross. On Easter, God opened the grave and Christ's resurrection spelled the defeat of the enslaving powers of sin and death. We too are redeemed through water---the waters of baptism---and God has now set us on our way to the promised land.

Nowhere do we experience this parallel more than at the Lord's Supper. "This is my body . . . this is my blood." The very Lamb of God has been sacrificed for us, and his blood covers us and our households from the curse of sin and death. Like the Israelite children, our children may also ask, "What does this ceremony mean to you?" (12:26). We now answer, "It is the new covenant Passover. The Lamb of God was sacrificed on the cross to free us from our sins and give us eternal life."
