When Paul mentions the Passover he is calling to mind one of the defining events for the Jewish people. The final plague of Exodus was to be the death of the firstborns in Egypt, but God’s people are spared because he has made a provision for them. The blood of the firstborns is replaced by the blood of a lamb. Its blood is smeared on the doors of the homes and death passes over God’s people. Paul now says to the church that Christ is this Passover lamb.
But the Passover calls to mind not only the passing over, but also the final deliverance from Egypt. The people were to prepare themselves for on the same night that Israel is passed over and death comes upon many in that land, there were to leave. They need to be ready to go and go quickly. Exodus 12:11 says this:
In this manner you shall eat it: with your belt fastened, your sandals on your feet, and your staff in your hand. And you shall eat it in haste. It is the Lord’s Passover.
Having your belt fastened is what is at times translated, “gird up your loins.” The idea behind it is be ready for travel. Don’t let your robes hang low and trip you up as you make your escape. Don’t just have your shoes by the door, put them on. Fasten your belt, tie your shoes laces–in double knots, have your car keys in hand and not on the table. Be ready to go immediately.
This hurry is why they eat the unleavened bread. Israel would have no time for their dough to rise. They needed to make haste.
Then as God had told them, it all comes to pass. Cries went up in the night “for there was not a house where someone was not dead.” Pharaoh summons Moses and Aaron in the night and commands them to go. He says, ““Up, go out from among my people, both you and the people of Israel; and go, serve the Lord, as you have said. Take your flocks and your herds, as you have said, and be gone, and bless me also!”
There is a great urgency for Egypt to rid itself of such a people that have brought God’s judgment upon them. They fear what may come next. So with such urgency in the land, it was in God’s wisdom that he prepared Israel to make haste. This great exodus was no small undertaking and it would have taken much preparation, and God had guided them through it. Here is what happened, beginning in verse 34 of Exodus 12:
So the people took their dough before it was leavened, their kneading bowls being bound up in their cloaks on their shoulders. The people of Israel had also done as Moses told them, for they had asked the Egyptians for silver and gold jewelry and for clothing. And the Lord had given the people favor in the sight of the Egyptians, so that they let them have what they asked. Thus they plundered the Egyptians.
And the people of Israel journeyed from Rameses to Succoth, about six hundred thousand men on foot, besides women and children. A mixed multitude also went up with them, and very much livestock, both flocks and herds. And they baked unleavened cakes of the dough that they had brought out of Egypt, for it was not leavened, because they were thrust out of Egypt and could not wait, nor had they prepared any provisions for themselves.
The book of Exodus then recounts the length of time that Israel had spent in Egypt, emphasizing the ending of that time and the beginning of a new day for Israel. Now they are freed. Generations of slavery have come to an end. So, when death pases over the people and Pharaoh finally tells Moses and his people, “Go!”, the only proper response is to leave. God did not bring about such a miraculous deliverance for his own people from the great worldly power of Egypt for them to remain in captivity. Israel’s response to God’s work and Pharaoh’s charge cannot be to linger. When Pharaoh says to leave, they shouldn’t say, “Give me a minute.” They can’t stay a moment longer. They can’t remain in slavery. God makes this point when he tells them to prepare themselves and dress appropriately for they won’t even have time for bread to rise. When God makes the way for his people, they must go. He desires to free them from Egypt and deliver them into a land that had been promised to them.
Paul is calling upon this theme of deliverance in 1 Corinthians. When he mentions that Christ is our Passover lamb he wants you to remember the Passover. The Passover is not only the sparing of Israel, it is the catalyst of their freedom. Likewise, Jesus is our sacrifice, sparing us from the consequence of our sin. He has taken the judgment on himself. But this Passover lamb was not sacrificed so that we can now linger in slavery. The church in Corinth is making a mockery of the sacrifice and is misunderstanding freedom in Christ. The arrogant sinning that is going on is nothing but a return to slavery. Paul wants them to understand and then live into a true freedom in Christ. His sacrifice is what brings us freedom to flee from captivity, leaving behind the chains of sin and the dominion of death.
Knowing that Jesus is our Passover, we ought to make haste to flee from sin and rush into his arms. We experience true freedom in him. We know the life we are intended to live when we are in Christ.
Using our freedom in Christ to return to sin is a return to slavery. Rather, just as Israel prepared itself to march out of Egypt into God’s guidance, we too must prepare ourselves. We are called to rid ourselves of such bondage, casting aside whatever weighs us down and entangles us because we have a race before us that we must run (Hebrews 12:1-2). We must be ready for a march into God’s promised land. We have a kingdom to be stewards of in this fallen world. We have a life of freedom that leads not to death, but to newness of life and life everlasting. So in our continuing work to leave the captivity of sin and live the life of a freed people, captive only to the righteousness of God, let us prepare ourselves as we are instructed in Ephesians 6, keeping in mind the way the Israelites were to prepare themselves on the night of their deliverance:
Therefore take up the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand firm. Stand therefore, having fastened on the belt of truth, and having put on the breastplate of righteousness, and, as shoes for your feet, having put on the readiness given by the gospel of peace. In all circumstances take up the shield of faith, with which you can extinguish all the flaming darts of the evil one; and take the helmet of salvation, and the sword of the Spirit, which is the word of God, praying at all times in the Spirit, with all prayer and supplication. To that end keep alert with all perseverance, making supplication for all the saints, and also for me, that words may be given to me in opening my mouth boldly to proclaim the mystery of the gospel, for which I am an ambassador in chains, that I may declare it boldly, as I ought to speak.
