The Promised Son of Abraham
Gen 15:1-21; Gal 3:16, 26-29
Introduction
I have shared before about the mission trip I went on to Peru when I was in college. Although we only planned to do three weeks of VBS, God gave us opportunities to do all kinds of other things.
One Sunday morning we were visiting a church in the jungle city of Quiabamba. And we were invited to back to the children’s Sunday School and talk with them. And they asked us to teach them an American church song. No one was ready for this, and as all these little grade-schoolers are looking at us, no one can think of anything.
Well, I immediately thought of my favorite song in Sunday School and stepped up and said, ‘I’ve got one!’ I am a notoriously bad singer and the other people just looking me like, ‘are you kidding?’ Undaunted, I explained this song had some motions, and everyone needed to spread out. And then I began to sing,
Father Abraham had many sons,
and many sons had father Abraham
You are one of them and so am I,
so let’s just praise the Lord
Now, I meant that as a little bit of joke. If you know the motions of that song, you know that the class can quickly descend into chaos. But the more I have thought about it – that song is great song. It teaches a profound biblical truth, and it does so in a way that once you learn it, you will never forget it.
This morning, I want us to see the meaning of that song and how it relates to Christmas and the birth of Christ. We are in our second week of looking at four promises God gave to different people about the birth of a son. And how all of these promises were ultimately fulfilled in the birth of Jesus Christ, God’s own Son.
Last week we looked at Genesis 3 and the story of Adam and Eve – the very first people and the very first sinners. They rebelled against God and sinned, even though God had told that to do so would mean death. They still sinned and were given a curse of death. And yet, God did not leave them to die in their sinfulness. But gave a promise of a Son who would come and redeem them. And that son was Jesus Christ.
This week we want to see more of the promise. You see God didn’t just make that promise to Adam and Eve. No, he keeps making the same promise. And each time he reveals more and more of his plan to send a Son to save sinners.
Several hundred years go by after Adam and Eve have lived and we are introduced to a man named Abram, whom God will eventually rename Abraham. And in Genesis chapter 12, we see God calling Abraham to leave his country, his family, all that he has to follow him.
The Lord says to him – Go from your country and your kindred and your father’s house to the land that I will show you. [2] And I will make of you a great nation, and I will bless you and make your name great, so that you will be a blessing.
Abraham responds to God’s call and begins to disentangle himself form his family, his land, his possession and follow God.
Then in chapter 14, Abraham mounts a rescue mission to save his nephew, Lot, who has been taken captive in a raid on his home town by warring kings. Abraham goes into battle against the kings and is victorious. However, when it comes time to divide up the loot, he refuses his portion.
This was not some noble sentiment on Abraham’s part – God has told him not to take it. You see, God had promised to bless him. If he accepted the wealth, then the king could have said that he was the one responsible for Abram’s prosperity, not the Lord.
After all of this, we come to chapter 15.
Genesis 15:1-18
After these things the word of the Lord came to Abram in a vision: “Fear not, Abram, I am your shield; your reward shall be very great.” [2] But Abram said, “O Lord GOD, what will you give me, for I continue childless, and the heir of my house is Eliezer of Damascus?” [3] And Abram said, “Behold, you have given me no offspring, and a member of my household will be my heir.” [4] And behold, the word of the Lord came to him: “This man shall not be your heir; your very own son shall be your heir.” [5] And he brought him outside and said, “Look toward heaven, and number the stars, if you are able to number them.” Then he said to him, “So shall your offspring be.” [6] And he believed the Lord, and he counted it to him as righteousness.
[7] And he said to him, “I am the Lord who brought you out from Ur of the Chaldeans to give you this land to possess.” [8] But he said, “O Lord GOD, how am I to know that I shall possess it?” [9] He said to him, “Bring me a heifer three years old, a female goat three years old, a ram three years old, a turtledove, and a young pigeon.” [10] And he brought him all these, cut them in half, and laid each half over against the other. But he did not cut the birds in half. [11] And when birds of prey came down on the carcasses, Abram drove them away.
[12] As the sun was going down, a deep sleep fell on Abram. And behold, dreadful and great darkness fell upon him. [13] Then the Lord said to Abram, “Know for certain that your offspring will be sojourners in a land that is not theirs and will be servants there, and they will be afflicted for four hundred years. [14] But I will bring judgment on the nation that they serve, and afterward they shall come out with great possessions. [15] As for yourself, you shall go to your fathers in peace; you shall be buried in a good old age. [16] And they shall come back here in the fourth generation, for the iniquity of the Amorites is not yet complete.”
[17] When the sun had gone down and it was dark, behold, a smoking fire pot and a flaming torch passed between these pieces. [18] On that day the Lord made a covenant with Abram, saying, “To your offspring I give this land,…”
1. The Promise of the Covenant (15:1-6)
Abraham has answered God’s call, he has just come through a battle he not intended to fight – surely he is worried. After all, he has no home land, he has rejected the wealth that he certainly could have used, and the kings he has defeated in battle may want to come for retribution.
In the midst of all these worries about security, the Lord comes to Abraham with words of comfort: Fear not, Abram, I am your shield; your reward shall be very great.
God assures that he will take care of him. He says ‘I am your shield’ – the Lord says that he will be the protection Abraham will need. He also says the Lord that awaits Abraham is greater than any tarnished loot offered by the king.
And yet, what is Abraham’s response? [2] But Abram said, “O Lord GOD, what will you give me, for I continue childless, and the heir of my house is Eliezer of Damascus?” [3] And Abram said, “Behold, you have given me no offspring, and a member of my household will be my heir.”
Is this complaining? Doesn’t he trust the Lord? Actually, the answer to both is ‘no.’ It is actually out of his faith that he inquires of God.
He believes that God will keep his promise, but he doesn’t see how. Remember what the Lord had promised him – offspring, descendants that would one day become a great nation. But he and his wife are childless and getting on in age. There appears to be no hope of him and his wife having a child of their.
So, as was the custom at the time, Abraham has already adopted one of his servants – Eliezar – to be his heir. He’s done this so that his wife will be taken care of when he dies. And now he reasons that this must be the one through whom God’s promise will be fulfilled.
But what does God say? “This man shall not be your heir; your very own son shall be your heir.” [5] And he brought him outside and said, “Look toward heaven, and number the stars, if you are able to number them.” Then he said to him, “So shall your offspring be.”
God is telling him, ‘Don’t try to help me out Abraham. I know your intentions are good; I know things look a little bleak – but remember the promise. You will have a son. And through that son, you will have many more sons – so many sons, in fact, that to try and count them would be like counting the stars in the sky. And it is through those offspring that I will make you a blessing to the nations of the earth.’
Adoniram Judson was one of the pioneers in the modern missions movement that began in the 19th century. He was a missionary to Burma. While serving, Judson lost two wives and several children to death in that difficult land. He saw very little fruit from his labors, and had many discouragements and setbacks.
To make matters worse, a war erupted between England and Burma. Judson, being a foreigner, was immediately imprisoned. In prison, as Judson lay sick with fever, he received a letter from a friend. In the letter, his friend – not knowing all that was happening – asked, “Judson, how’s the outlook?” You can imagine what Judson could have put in his response!
“Judson, how’s the outlook?” Judson replied, “The outlook is as bright as the promises of God!”
Though Judson could not clearly see what God was doing, he believed God. He trusted him. He trusted him that when the gospel is preached, people will be saved. And so, even in the midst of great darkness, Judson still trusted God.
Likewise, we are told Abraham did the same. Though he could not see how God would fulfill his promise, he believed he would. Verse 6 says. And [Abraham] believed the Lord, and he counted it to him as righteousness.
Listen to that again, “Abraham believed the Lord and he credited it to him as righteousness.” Now notice what it does not say. The text does not say that …
Abraham was righteous and God recognized it.
Abraham believed and God made him righteous.
No, the text says that Abraham trusted – had faith in – the Lord. And because he had faith, the Lord credited to him, or declared him to be righteous.
Within Christianity, this is what faith is. Faith is simply trusting the promises of God. Faith is not righteousness. But faith is the means by which we receive righteousness from God. It is the conduit by which God gives what we need to be with him.
This is why even once we get to the New Testament, Paul can say in Ephesians 2, “For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast.”
Abraham was man of God not because he earned, not because he was righteous, not because he was born into it – he was part of God’s people because – by God’s grace – he trusted in the promises of God.
2. The Grace of the Covenant (15:7-18a)
God has reaffirmed his promise to Abraham – the promise of offspring. And now he affirms that his offspring will be given the land of Canaan to dwell in. But again, Abraham can’t see how it will happen.
After all, it’s not like Canaan was uninhabited. Imagine God appearing to you and saying that you were going to have so many children, grandchildren, and great-grandchildren that he is going to give you the entire state of Michigan for them to live. Well, Michigan’s not exactly an untamed wilderness. What about all the people?
The same is true for Abraham. He thinks about all the people in Canaan and wonders, how am I going to get all this land? Will I have to wage war for it?
So, the Lord tells Abraham, ‘Okay, I’ll show you how this going to happen.’ And he tells him to gather together some animals. “Bring me a heifer three years old, a female goat three years old, a ram three years old, a turtledove, and a young pigeon.” [10] And he brought him all these, cut them in half, and laid each half over against the other. But he did not cut the birds in half.”
What is described here is the cutting of the covenant. Now, I am not trying to be funny with that description. While our English translations say that the Lord ‘made a covenant’ in v. 18, it literally says ‘cut a covenant’ in the original.
And in reading the text, we know why the ancient Hebrews called making a covenant, “cutting a covenant.” But what’s the point? This seems like an awful gory way of sealing a deal. And that’s really the point here.
You see, when we have contracts today, we almost always have built-in consequences for breaking the contract. If you ever get something in the mail, this is the tiny, like 4-point font on the bottom of the last page.
These days, when it comes to marriage, there is a strong suspicion that the other person will not keep the promises they make in the marriage ceremony. So, they layout the consequences ahead of time through prenuptial agreements. There, you might lose a car or a summer home, but that’s nothing compared to these ANE covenants.
When two people cut a covenant, it meant that they were both obligated to do something. It could be to protect one another from invaders (you defend me and I will defend you). It could have been the selling of land; all kinds of things.
After they cut the animals in two, they would both walk (usually hand-in-hand) between the halves of the animals. As you did this, you couldn’t help but look down at the carcasses. The point was – if you break the covenant, this is what is going to happen to you. If you break this covenant, your life is forfeit, and the birds of prey will be seeking to land over your lifeless body.
But notice what happens here – verse 17, When the sun had gone down and it was dark, behold, a smoking fire pot and a flaming torch passed between these pieces. [18] On that day the Lord made a covenant with Abram,
Who walks through the animals? Not Abraham; he’s out cold in a deep sleep. No – in an almost unbelievable turn of events – it is God himself, and God alone who passes through the animals. God is humbling himself before Abraham, placing himself under this threat of death.
God is saying, “Abraham, this is an unconditional covenant. No matter what you do, I alone will be responsible for seeing it completed.” The promises that God make here are not dependent on what Abraham. They are dependent on God and his grace.
And that’s good, because what do we see in the next few chapters? If you read Genesis before, you’ll know that Abraham doesn’t do so well at first. The promised doesn’t come for several years, so Abraham’s wife talks him into sleeping with one of the servant girls to have a son. As he travels, he lies about his wife being his sister, and she almost taken as wife to another man.
Over and again, Abraham’s actions keep threatening to jeopardize the fulfillment of the covenant. But every time he messes things up, God steps in corrects the situation. The Lord proves himself faithful – faithful to his promise; faithful to his covenant; and powerful enough to see it through to the end. Nothing will interfere with it because he has determined to bring it about.
3. The Fulfillment of the Covenant
Here, we must go beyond Genesis 15 to see how God fulfills his promise to Abraham.
The Lord visited Sarah as he had said, and the Lord did to Sarah as he had promised. [2] And Sarah conceived and bore Abraham a son in his old age at the time of which God had spoken to him. [3] Abraham called the name of his son who was born to him, whom Sarah bore him, Isaac. [4] And Abraham circumcised his son Isaac when he was eight days old, as God had commanded him. [5] Abraham was a hundred years old when his son Isaac was born to him. [6] And Sarah said, “God has made laughter for me; everyone who hears will laugh over me.” [7] And she said, “Who would have said to Abraham that Sarah would nurse children? Yet I have borne him a son in his old age.”
The Lord fulfilled his promise by giving Abraham a son. And through that son, Isaac, God continued to fulfill his promise to Abraham.
Isaac goes on to have two sons, Jacob and Esau. By God’s grace, though he is the younger of the two, Jacob is chosen by God to receive the promised blessings to Abraham. As a result, Jacob is given several sons who become an extended family.
In Exodus 1, we read that, These are the names of the sons of Israel who came to Egypt with Jacob, each with his household: Reuben, Simeon, Levi, and Judah, Issachar, Zebulun, and Benjamin, Dan and Naphtali, Gad and Asher. All the descendants of Jacob were seventy persons . . . [And] the people of Israel were fruitful and increased greatly; they multiplied and grew exceedingly strong, so that the land was filled with them.
In fact they become so large that they numbered as many as a small nation. And while living in Egypt, the Egyptians became afraid of them thinking they would take over the country.
God fulfilled his promise to provide a son in Isaac, he began to fulfill his promises to make his offspring as great as the numbers of stars in the sky. God would continue to fulfill his promises and allow these sons of Jacob – now the nation of Israel – to continue to grow in large numbers. However, they still never grew to be a large nation.
And what we see in Bible, is that God doesn’t fulfill these promises to Abraham literally, he also fulfills them spiritually – in ways that Abraham could never have imagined, but will surely cause him to rejoice in forever in heaven with God.
How does God do this? Through Jesus Christ.
The New Testament begins with these words – [this is] The book of the genealogy of Jesus Christ, the son of David, the son of Abraham (Matt 1:1). In the context of that verse, Matthew is making a certain argument for his Jewish readers. But there is more to it than simply saying that Jesus’ lineage was truly Jewish.
In Romans 15, Paul says, “Christ became a servant to the [Jews] to show God’s truthfulness, in order to confirm the promises given to the patriarchs.” The patriarchs are Abraham, Isaac, and Jacob – those to who first received the promises of God. Paul says Christ came to show God was faithful to those promises.
What does that mean? It means that until Christ came, the covenant promises were not yet fully realized. What God did was simply foreshadowing – pointing forward – to the true fulfillment of the promise.
That’s why in his letter to the Galatians, Paul makes it even more specific. He says, Now the promises were made to Abraham and to his offspring. [The OT passage] does not say, “And to offsprings,” referring to many, but referring to one, “And to your offspring,” who is Christ.
Jesus Christ is the ultimate fulfillment of God’s promise to Abraham. God said, ‘Abraham, I will give you a son through whom all nations of the world will be blessed.” And in Abraham’s lifetime, Isaac was born and physical line of descent is created. And in that line of decent, comes another Son – Jesus Christ.
And more than Israel could have ever done, the entire world is brought blessing through that promised Son, Jesus Christ. Why? Because Christ lived and died and was raised back to life so that sinners could be made right with God. He gave his life in place of sinners so that they might have their sins forgiven.
And so are back where we started – with that song.
Father Abraham had many sons,
and many sons had father Abraham
You are one of them and so am I,
so let’s just praise the Lord
What does this song mean? It means that we act as Abraham did, and place our faith in God. Specifically, when we believe God when he says Jesus Christ is the substitute for our sins and by trusting him we will be saved from the wrath to come, then we are brought into God’s people.
We are considered to be ‘in Christ’ – to belong to him as one of his people. And in Galatians 3, Paul makes this incredible observation – If you are Christ’s, then you are Abraham’s offspring, heirs according to promise.
If you put your faith in Christ, then you become part of the fulfillment of God’s promise to Abraham. Spiritually, you become one of those uncountable descendents that God promised him.
In the last book of the Bible, the book of Revelation, the apostle John is given a vision of heaven itself and he sees those who are God’s people. Those who from the beginning of time until the end of time have placed their faith in God for salvation. And what does he see? He says,
I looked, and behold, a great multitude that no one could number, from every nation, from all tribes and peoples and languages, standing before the throne and before the Lamb, clothed in white robes, with palm branches in their hands, [10] and crying out with a loud voice, “Salvation belongs to our God who sits on the throne, and to the Lamb!” [11] And all the angels were standing around the throne and around the elders and the four living creatures, and they fell on their faces before the throne and worshiped God, [12] saying, “Amen! Blessing and glory and wisdom and thanksgiving and honor and power and might be to our God forever and ever! Amen.”
Conclusion
Through Christ the promises to Abraham are fulfilled. Through Christ, God reverses the effects of humanity’s fall into sin. Through Christ, sinners are made righteous. Through Christ we who are separated from God by our sin are made to be his people.
This is what Christmas is all about – the coming of the promised Son.
