Covenants, Old and New

Did you know that “communion” or the Lord’s Supper has roots in Exodus? We miss so much of the necessity and beauty of Jesus’ ministry on our behalf because we do not know and appreciate the Old Testament. It’s exciting to learn, though, and I pray God continues to speak through His Word and deepen your walk with Him – during communion in your church and every day!
*************************
Luke 22:20
Likewise He also took the cup after supper, saying, “This cup is the new covenant in My blood, which is shed for you…” (NKJV)
Those words are probably familiar with anyone who has spent much time in churches where the Lord’s supper (communion) is celebrated. Sometimes, because we usually lack a solid understanding of the Old Testament (and the Old Covenant), we fail to really appreciate what Jesus was saying here. Let’s take a look.
In Exodus 19:5-6a, God makes a tremendous offer to Israel. ‘Now therefore, if you will indeed obey My voice and keep My covenant, then you shall be a special treasure to Me above all people; for all the earth is Mine. And you shall be to Me a kingdom of priests and a holy nation.’ The people enthusiastically agree in verse 8: Then all the people answered together and said, “All that the Lord has spoken we will do.”
Much like a marriage, Israel is entering a unique covenant relationship with God. In fact, throughout Scripture God refers to Israel as a wife (usually an unfaithful one!) And like a marriage, this is a 2-sided covenant. Notice God’s stated condition: if you will indeed obey My voice and keep My covenant. Chapters 20-23 are a bit like a “preview” of the rest of the law before the covenant is officially ratified.
We will discuss more in future posts why the law was (and is) important. What we are going to focus on today is the three-part process of ratification, or official enactment, of the covenant in chapter 24. Please read this whole chapter on your own, as I will only be pulling out a few verses here.
**Part One: Blood**
Exodus 24:7-8 Then he took the Book of the Covenant and read in the hearing of the people. And they said, “All that the Lord has said we will do, and be obedient.” And Moses took the blood, sprinkled it on the people, and said, “This is the blood of the covenant which the Lord has made with you according to all these words.”
What is the deal with the blood??? In ancient times, if someone wanted to solemnly swear and oath and “cut covenant,” they would take some animals, cut them in two, and arrange them so that the two people who were forming a covenant would walk through the halves. Disgusting, but meaningful. The idea was: if I break my end of this agreement, may I be like these poor animals here. May this be like my blood.
[Check out Genesis 15 - that is exactly what God is doing with Abraham. Only... Abraham doesn't walk through! Only God does! His promises to Abraham were unconditional, because Abraham didn't have any conditions to fulfill in the covenant!!]
As Moses sprinkles the blood all over the people, this was a solemn thing. They understood what was happening: if I break my end of this 2-sided covenant, my blood is on my own head.
**Part Two: Meal**
Exodus 24:9-11 Then Moses went up, also Aaron, Nadab, and Abihu, and seventy of the elders of Israel, and they saw the God of Israel. And there was under His feet as it were a paved work of sapphire stone, and it was like the very heavens in its clarity. But on the nobles of the children of Israel He did not lay His hand. So they saw God, and they ate and drank.
This is definitely one of those passages that seems like should tell us more! But, apparently this is all we need to know. As they ratify the covenant, the leadership of Israel goes up the mountain and literally has a meal with God.
**Part Three: Writing**
Exodus 24:12 Then the Lord said to Moses, “Come up to Me on the mountain and be there; and I will give you tablets of stone, and the law and commandments which I have written, that you may teach them.”
This is pretty self-explanatory – God writes out the covenant on tablets of stone and instructs Moses to teach the people.
Now… what does this have to do with communion?? I know I’ve never heard a communion message from Exodus!! :) Let’s go through the 3-part process of ratification for the new covenant.
**Part One: Blood**
Luke 22:20 Likewise He also took the cup after supper, saying, “This cup is the new covenant in My blood, which is shed for you.
Remember the Old Covenant? The blood was sprinkled on them, symbolizing their blood! You break this covenant, your blood is on your own head! What’s different now? It’s not my blood! It was Jesus’ blood shed for me!
**Part Two: Meal**
Luke 22:14-15 When the hour had come, He sat down, and the twelve apostles with Him. Then He said to them, “With fervent desire I have desired to eat this Passover with you before I suffer; for I say to you, I will no longer eat of it until it is fulfilled in the kingdom of God.”
Another meal… again symbolizing the fellowship within a new covenant relationship.
**Part Three: Writing**
Hebrews 8:10 “For this is the covenant that I will make with the house of Israel after those days, says the Lord: I will put My laws in their mind and write them on their hearts; and I will be their God, and they shall be My people.”
The law isn’t on tablets anymore – it’s on our hearts and in our minds!
Thank you, Lord, for Jesus Christ! Thank you for promising Him way back in Genesis 3, and then faithfully revealing your plans, purposes, ways, and character throughout Scripture. Where would we be without His blood shed on our behalf? Our blood would be on our own heads, for we can never be holy as you are.
I Corinthians 6:9,11
Don’t you know that those who do wrong will have no share in the Kingdom of God? … but now your sins have been washed away, and you have been set apart for God. You have been made right with God because of what the Lord Jesus Christ and the Spirit of our God have done for you. (NLT)
