On the tenth of this month every man shall take for himself a lamb ... a lamb for a household.
Then the whole assembly of the congregation of Israel shall kill it at twilight. And they shall take some of the blood and put it on the two doorposts and on the lintel of the houses where they shall eat it.
It is the Lord's Passover. For I will pass through the land of Egypt on that night, and will strike all the firstborn in the land of Egypt.
- Exodus 12:3, 6-7, 11-12
The lamb was God's appointed means of safety, of deliverance from judgment. The blood upon the doorposts outside was sufficient for God's eye to rest upon: "When I see the blood, I will pass over you, and the plague shall not be on you to destroy you" (Exodus 12:13).
Therefore this people, taken up in God's sovereign grace, could, behind the blood-stained lintel, rest satisfied in perfect safety and feast upon the lamb roast with fire, with the unleavened bread and the bitter herbs.
In all this we see a clear, plain picture of Christ. "For indeed Christ, our Passover, was sacrificed for us" (1 Corinthians 5:7). The blood gave Israel safety and peace. The blood of Christ secures salvation and peace, as well as forgiveness of sins and the gift of eternal life, to every soul today who hears and believes the message-- receiving the incorruptible word of God into the heart by faith.
Thus, Israel starts on their journey as a redeemed people, and that memorial month was for them the beginning of months (Exodus 12:2). So with us: When the soul accepts God's Lamb, there is a new beginning, a new birth, a new life, and a new relationship. All are based upon the blood of Christ, God's Lamb. Blessed start, blessed journey, blessed end.
