The whole assembly must kill the lamb (12:6)
Each person in the camp of Israel was responsible for the slaughter of the lamb. Every one of us is guilty of the death of Jesus Christ. The Jewish and the Roman nations [Jews and Gentiles] crucified the Lord; so spiritually speaking we are all as guilty as they (Matthew 27:17-25; Acts 4:26-28). The Bible condemns every person who has ever lived as sinners (Romans 3:10,23). It was our sin that caused the crucifixion of Christ.
The blood applied to the doorposts (12:7,13,22)
Only those who did as God commanded were saved from the death that visited Egypt. No blood, no deliverance. As Christians, we understand that the atoning blood of Jesus Christ is the foundation of our salvation. Just as the blood was smeared on the doorposts and lintels of each Hebrew household (forming a cross shape), so His blood must be applied to each individual life (Revelation 7:14; 1 Peter 1:18-19).
The lamb had to be eaten (12:8-10)
We clearly see that the body and blood of the lamb speaks of the body and blood of the Lord (Matthew 26:26-28). Remember that the Old Testament ‘shadows’ are spiritually fulfilled in Christ. Just as blood is not literally smeared on us, so it follows that we do not literally eat Christ’s flesh. Both are spiritual in nature when we partake of the Lord’s Supper.
The lamb must be eaten in haste (12:11)
Once delivered through the blood of the Passover lamb, the Jews needed to exit Egypt as quickly as possible. The sinner, who receives Christ as Saviour, must flee the world that has held him in bondage for so long (1 Peter 1:13-14). We too must have our shoes on (Romans 10:15; Ephesians 6:15), and our staff should be in our hand (our authority in Christ – Matthew 28:18-20).
It is ‘The Lord’s Passover’ (12:11)
The focus of the Jew’s attention was on God Himself. This celebration was never to become a religious observance. The Lord’s Supper causes us to focus on Christ. Some churches have missed the point by exalting the bread and the wine. The point of the Passover and the Lord’s Supper is to remember Him (1 Corinthians 11:23-26). This is why Exodus 12:14 calls the Passover a ‘memorial.’ As we observe the celebration we remind ourselves of exactly what God has done for us through the blood of His Lamb.
At the evening (Deuteronomy 16:2,6)
The lamb was slain in the evening. Matthew 27:45-46 informs us that the Lamb of God, Jesus Christ, was crucified in the evening also. Many churches observe the Lord’s Table in the morning service, but this simply follows the traditions of the Roman Catholic Church. If the Passover and the Last Supper were celebrated in the evening, it would appear that such timing should apply to our observance of that Lord’s Table too.
No bone broken (12:43-46)
Why were the Jews commanded not to break any of the lamb’s bones? Such an instruction seems rather pointless unless it has a spiritual / prophetic application. God designed yet another sign that would eventually convince the Jews of the fact that Jesus Christ is truly the Messiah. His bones were not broken as He hung on the cross (John 19:33). Break the bones would obviously inflict intense suffering on the lamb ready to be slaughtered, so too with Christ. What is God telling us here? It is the blood, not the suffering, which atones for the sinner. The Bible never speaks of Christ’s suffering as a means of salvation, it is always His blood. Yes, He suffered (Hebrews 13:12), but it is still His blood that actually saves (Hebrews 9:22). God wants His people to focus on the blood not the suffering.
Outside the gates (Deuteronomy 16:5)
The lamb was killed outside the gates of Jerusalem once the Jews came into the Promised Land. The crucifixion of Christ took place outside of Jerusalem too. John 19:16-19 tells us that this place was called Golgotha. Paul makes the connection between the two events also (Hebrews 13:10-13).
