Interlude: Why was Abraham so Important to Paul?
Genesis 15 & Psalm 2
As I was preparing to preach on the central part of Paul’s letter to the Galatians, beginning with Chapter 3, it occurred to me that it would be an understatement to say that Paul spends a lot of time talking about Abraham. A lot. Not just about Abraham himself, but about a whole host of themes that go back to Abraham’s story. Themes like faith and faithfulness, seed and inheritance, and of course righteousness. And as I was thinking about that and especially about the reason why Paul spends so much time talking about Abraham, it occurred to me that today would be a good time for an interlude before we launch into Paul’s grand argument. That’s what I’d like to do this morning.
So why does Paul talk so much about Abraham? The way some commentators talk, you might think that Paul was doing nothing more than proof-texting. He needed an example of faith over works from the Hebrew scriptures and, voila, there was Genesis 15. Or, it’s possible that the agitators in Galatia were appealing to Genesis 17, the passage where the Lord gave the covenantal sign of circumcision to Abraham. So, naturally, Paul goes two chapters back to show that well before circumcision was a thing, there was faith. But Paul had a greater reason than any of that. Paul never engages in shallow proof-texting. And Paul never talked about theology or doctrine in the abstract the way people often do today. Paul told a story and Abraham was important to Paul, because Paul saw the gospel as the culmination of the great story of the God of Israel and his people and of his promises and of his faithfulness and how it all comes to fulfilment in Jesus the Messiah. Everything for Paul rides on that great story and it begins with Abraham, because God’s calling of Abraham was the answer—or, at any rate, the beginning of the answer—to the mess into which the human race and the whole word have fallen. Right from the get go, Adam went wrong. Because of his rebellion against God Adam was cast out of the garden temple he’d been created to steward, and he was cut off from the life of God. And from there his descendants went from bad to worse. Even wiping out the whole human race in a flood, while saving the one righteous man left, even that didn’t fix the problem. From righteous Noah it’s only a turn of the page to the Tower of Babel. All of humanity had lost the knowledge of God. The world was lost in darkness. And then out of the darkness the Lord called Abram: “Go forth from your land and your birthplace and your father’s house to the land I will show you. And I will make you a great nation and I will bless you and make your name great, and you shall be a blessing…all the clans of the earth through you shall be blessed.” And, the storyteller records, “Abram went forth as the Lord had spoken.”
For years Abram believed and trusted this strange God who had called him to Canaan and made him an outrageous promise. And the Lord blessed Abram with sheep and cattle and camels, he blessed him with a great reputation, he defeated king for him, but the central part of that promise—the land and especially the family never came to pass. And so, in Genesis 15, the Lord speaks to Abram again:
After these things the word of the Lord came to Abram in a vision, saying, “Fear not, Abram, I am your shield. Your reward shall be very great.” And Abram said, “O my Lord, God, what can you give me when I am going to my end childless, and the steward of my household is Eliezer of Damascus?” And Abram said, “Look, to me you have given no seed, and here a member of my household is to be my heir.”
Seed. A family. Children. At least one single son to be his heir. The promise required at least that in order to be fulfilled. But Abram was an old man. His wife was long past her child-bearing years. It looked like everything would soon pass to Abram’s servant, Eliezer, and the promise would be dead. As I read Abram’s protest here, I can’t help but think of the father of the possessed boy in Mark’s gospel. He cried out to Jesus, “I believe, but help my unbelief.” Abram knew this strange God was real. Of all the gods, this was the only who had ever spoken. And Abram had followed him to Canaan, and there this God provided And now, years later, Lord was no longer a stranger. The Lord was real, but would he prove to be truly faithful to his promise? The story goes on:
And now the word of the Lord came to him, saying, “This one will not be your heir, but he who issues from your loins will be your heir.” And he took him outside and he said, “Look up to the heavens and count the stars, if you can count them.” And he said, “So shall be your seed.” And he [Abram] trusted in the Lord, and he [the Lord] reckoned it to him as righteousness.
The Lord reiterated his promise to Abram: a promise of seed and a promise of an inheritance. And Abram, looking back on the Lord’s faithfulness so far…this God who had started out a stranger to him, but was now a faithful friend…Abram had faith. Some translations say he “trusted” and others he “believed”. The Hebrew word has a pretty clear sense of trusting in someone or something who has proved himself trustworthy, reliable, faithful. Despite that, I’ve noticed that we often struggle to get this part of the story right. A lot of us hear those words, “Abram believed…” or “Abram had faith…” and we think of this as something Abram did with only his brain. Knowing what he did of the Lord, he gave his intellectual assent to this promise. For a lot of us “belief” or “faith” is mainly a thinking word and in large part that’s because in our Protestant tradition we’ve tended to drive a wedge, to set up a wall between faith and works. The Reformers were right when they said that salvation is by faith alone, but that doesn’t mean that faith is just something we do in our heads. Faith is organically intertwined with trust and trust is organically intertwined with obedience. Faith in a God whom we know to be faithful naturally works itself out in how we live. Abram followed where the Lord led him, because that’s the nature of faith.
It's worth taking note of how the later Jews translated this into Greek. Greek has a word group for belief that puts the emphasis on our brains and on thinking. Dokeo. It’s the dox in orthodox, which means to believe or to think the right thing. But instead, the translators of the Old Testament chose the word pisteuo. Sometimes this pistis word group can get into the brainy, the thinking aspects of belief, but most of the time it’s more like that Hebrew word. It's not just intellectual assent, it’s not just thinking the right things, it means to trust, to give yourself over to someone or something proved to be faithful. In the Greco-Roman world, pistis was the sort of loyalty, allegiance, and trust around which communities were built.
This language of trust was how the Jews thought and it’s how the early Christians thought. It’s a sad part of our history that over the centuries we’ve tended more and more towards the idea of faith as primarily a thinking thing. Consider how we think of the creeds. We usually think of them as a set of theological propositions. I believe in God the Father. I believe in Jesus Christ, his only son our lord. I believe in the Holy Spirit, who proceeds from the Father and the Son. We think of these as bits of abstract doctrine that define right belief—again, that’s what “orthodoxy” means. We learn the creeds and we give them our intellectual assent. It’s something we do with our brains. And that’s good so far as it goes, but consider that the creed started out in the early church as a baptismal affirmation. People—pagans—encountered the good news about Jesus and the faithfulness of the God of Israel, they heard the story that went back all the way to Abraham—of this God who gave promises and then kept them, of a God unlike anything they knew in the pagan pantheon, of a God who reveals himself in Jesus, his incarnate son, of a God who gives his life for the sake of his people—and they believed. They put their trust in this God who made heaven and earth; in this God who revealed himself in his son, born of Mary, crucified under Pontius Pilate, and who rose three days later; in this God who now gives his own Spirit to quicken, to enliven his people. Like Abraham, they were leaving behind their countries and their families, and stepping out in trusting faith into a new world and into a new life in which they were risking persecution and even martyrdom. Their faith wasn’t just an intellectual exercise; they were entrusting their whole selves to this God whose story they confessed in the creed, a story that was now their story.
I’ve been reading Teresa Morgan’s newish book on the language of faith in early Christianity and she very helpfully puts it this way, “The translators [of the Greek Old Testament] regularly chose pistis language at moments of change and decision-making, when the relationship between God and his people is portrayed as entering a new phase, or a covenant is made which will create or shape Israel in the future.”[1] It’s language of trust, and of loyalty, and of obedience—not just something that happens in the brain. God is doing something new, maybe even strange or bewildering, and this is the language of his people committing themselves to him in this new thing, because they know him to be faithful.
And I think that now moves us from the “Abram trusted” part of Genesis 15:6 right to the “and the Lord reckoned it to him as righteousness” part. What does that mean? Well, how we read this—probably for most of us, whether we realise it or not—has been shaped by Martin Luther and the Reformers. Luther confronted the medieval church, which was falsely teaching a theology of merit, a gospel in which our works and the works of the saints earn us a place in God’s presence—one we could even buy with money. Luther believed—actually this is a good example of that idea of trust, because this wasn’t just a thinking exercise for Luther, he put his life on the line for the gospel—but Luther believed that salvation is by grace alone through faith. He was right. And this was one of the key passages he drew on. The problem was that Luther was reading Sixteenth Century problems back into Paul’s First Century letter to the Galatians and back into Abraham’s story in Genesis. And that meant that Luther was sort of looking for the right answer in the wrong place—or maybe, better, asking the wrong question of the right text. And so, in light of the works-righteousness he was arguing against, Luther took “righteousness” to mean a moral quality—one that we sinners lack and one that Jesus has. So for Luther, when Paul cites the story of Abram and how Abram believed and it was reckoned to him as righteousness, that meant that when we put our faith in Jesus, a sort of legal transaction takes place in the heaven courtroom, and Jesus’ righteousness becomes our righteousness and we become acceptable to God. And I think if Paul were alive to hear that, he'd give us a bit of a funny look and say, “Well, if righteous did mean some kind of moral status, then I guess you’d be right, but that’s not what righteous means. Righteousness is about our God’s covenants.” Because for Paul, to be reckoned as “righteous” was first and foremost about being part of God’s covenant people—about living in his promises—because that’s what Genesis 15 is about. Let’s look back at the rest of Genesis 15, beginning at verse 7. We’ve been told that Abram trust in the Lord’s promise and that the Lord reckoned it to him as righteousness. The rest of the chapter tells us what that means.
And he said to him, “I am the Lord who brought you out of Ur of the Chaldees to give you this land to inherit.” And he said, “O my Lord, God, how shall I know that I shall inherit it?” And he said to him, “Take me a three-year-old heifer and a three-year-old she-goat and a three-year-old ram and a turtledove and a young pigeon.” And he took all of these and clove them through the middle, and each set his part opposite the other, but the birds he did not cleave. And carrion birds came down on the carcasses and Abram drove them off. And as the sun was about to set, a deep slumber fell upon Abram and now a great dark dread came falling upon him. And he said to Abram, “Know well that your seed shall be strangers in a land not theirs and they shall be enslaved and afflicted four hundred years. But upon the nation for whom they slave I will bring judgement, and afterward they shall come forth with great substance. As for you, you shall go to your fathers in peace, you shall be buried in ripe old age. And in the fourth generation they shall return here, for the iniquity of the Amorites is not yet full.” And just as the sun set, there was a thick gloom and, look, a smoking brazier with a flaming torch that passed between those parts. On that day the Lord made a covenant with Abram, saying, “To your seed I have given this land from the river of Egypt to the great river, the river Euphrates.
So in response to Abrams’ faith, the Lord establishes a covenant with him. In Abram’s culture this is how binding agreements were made. Two parties would work out the details of the agreement. Maybe it was two kings pledging military support to each other. It might be two rich men established a boundary between their lands. It might be a king and his vassal, the vassal pledging a tribute and the king pledging to defend his vassal with his army. They would clearly state the conditions of the covenant and then they would make a sacrifice. They might slit the throat of a bull, saying in other words, may this be done to me if I am not faithful to what I have promised. And this is what happens here in Genesis 15. In response to Abram’s faith, the Lord comes to Abram in this sombre ceremony to ratify his covenant promises. He passes through this pathway between the halved carcasses of the animals Abram has slaughtered, as if to say, “May this happen to me if I am faithless.” This is, I think, one of the most profound passages in the Bible with regard to the Lord’s faithfulness. And this is what Paul is retrieving in his argument with the Galatians. It’s why he talks about things like “seed” and “inheritance” and it’s why he talks about faith and faithfulness and righteousness. He’s saying that in the gospel, in the good news about Jesus, the crucified and risen Messiah, we see the ultimate example of the faithfulness of God to his promises and that through faith in Jesus we become part of this covenant community in which God has pledged himself to us.
So this is why Abraham was so important for Paul. This is why he talks about Abraham’s seed and Abraham’s inheritance to the Galatians. But it might not be so obvious how he connects it to Jesus. So…there’s more to the story of God and Israel than Abraham. As the story goes on other actors walk on stage and eventually one of those will be Israel’s king. And so Paul also recalls Psalm 2, which is one of the “royal psalms”. It begins with the nations raging. The kings of the earth plot together against the God of Israel, but the Psalmist sings:
He who sits in the heavens laughs;
the Lord holds them in derision.
Then he will speak to them in his wrath,
and terrify them in his fury, saying,
“As for me, I have set my King
on Zion, my holy hill.”
I will tell of the decree:
The Lord said to me, “You are my Son;
today I have begotten you.
Ask of me, and I will make the nations your heritage,
and the ends of the earth your possession.
In Genesis the Lord promised the land as an inheritance to Abraham, and in Psalm 2 that promised inheritance is given to the coming Davidic king, but it’s expanded—from the land of Canaan to the ends of the earth. And Paul brings these two promises, these two covenants together in Galatians. It’s not just the Lord’s promise to Abraham that is fulfilled in Jesus, but his promises to the king, too. And that’s important. Remember what I said last week about the king and his people. The king represents his people. What’s true of him is true of them. And that means that the inheritance promised to Abraham now belongs to King Jesus and his people.
This was vitally important to Paul, because for Paul the most important thing about the gospel is that in it God reveals, he proves his faithfulness and, in response, we give him glory. I think we often miss this. For Paul the gospel was centred on God, but we often centre the gospel on us. Brothers and Sisters, the gospel is for us, but it’s not about us. I can’t really say it any better than Tom Wright does. He makes the point that “Paul understood…[his]…mission not simply as a way of ‘getting people converted…” because that would be a human-centred gospel…“but as the symbolic as well as actual means of extending and displaying the reign of Israel’s God, and of his ‘Son,’ to the ends of the earth.”[2] In other words, the gospel—and the proclamation and spread of the gospel out into the pagan world—was the fulfilment of God’s promises, proving his faithfulness, and ultimately to bring the nations before him in glory and praise.
Now, if we have any lingering doubts about this covenantal meaning of “reckoning it to him as righteousness”, I think there’s one more passage that clears it up. Psalm 106:30-31 praises Aaron’s grandson Phinehas. You might remember that I mentioned him a few weeks ago. The Psalm says:
Then Phinehas stood up and intervened,
and the plague was stayed.
And that was counted to him as righteousness
from generation to generation forever.
Phinehas intervened. Specifically, he speared one of the Israelites along with his Moabite mistress as they were, so to speak, in the act. And for that act of faithfulness, the Lord appointed Phinehas and his descendants to a special role in Israel’s priesthood. Or as the Psalmist says, his act was counted to him as righteousness from generation to generation forever. In response to Phinehas’ faith, the Lord established a covenant with him—he made a promise to him. In this case, it’s clear that “reckon as righteousness” doesn’t mean that the Lord credited Phinehas with a moral surplus and it doesn’t mean that for Abraham either. It’s about God’s covenant, which he established with Abraham and his “seed”. And this is what Paul’s picking up on in Galatians when he makes his argument that the gentiles are just as much a part of God’s family in Jesus as the Jews are—that these formerly unclean pagans are as much and as really Abraham’s descendants as he, a “Hebrew of Hebrews” is. “If you belong to the Messiah,” Paul writes in 3:29, “you are Abraham’s family (his seed) and you stand to inherit the promise.”
But family and land weren’t the only things the Lord promised in his covenant to Abram. The Lord also promised that Abraham’s family would become slaves in Egypt, but that he would ultimately rescue them. This is as much a part of what Abraham’s family will be as all the other things the Lord promises. From the beginning, the Lord establishes this family as a rescued-from-slavery people. It’s in their covenantal DNA. It literally comes to pass just as the Lord said, but since this is in their DNA, it’s the lens through which the Jews would forever see themselves. That’s why in Paul’s day saw this as their ongoing story. It was a story of blessing followed by the curse of exile, but one day—because it’s who God had made them as a people—one day their God would come and rescue them again and live in their midst.
So Paul shows how the gospel embodies and fulfils this promise of seed and inheritance to Abraham, he shows how it embodies and fulfils the promise of slavery and rescue, and that means that, third and finally, the gospel also embodies and fulfils the exodus promise of God to dwell in the midst of his people. The prophets sometimes explained God’s presence in the temple in terms of his Spirit and this, I think, explains how Ezekiel and Joel could promise that God would renew his people by means of his Spirit. This was the future that Israel’s story looked towards: an end of exile and God’s presence through his renewing Spirit. And this is why Paul, as part of his argument in Galatians, points to the present indwelling of the Holy Spirit in the people of God, as the earnest or the down payment, of the foretaste or firstfruits of the ultimate fulfilment of the Lord’s promised inheritance to Abraham.
And that brings us back to the creed. My point has been that Paul, rather than talking about abstract theological propositions, tells a story—the story of God and his people, of his promises and their fulfilment—and our place in that story. The people from James and the agitators in Galatia, they knew that story, but they were leaving important parts out, so Paul goes back to the beginning and tells it all again, to show them the bits they missed—or maybe the bits they remembered, but hadn’t yet learned to see in light of Jesus’ death and resurrection. It is kind of remarkable how, as Paul tells us the story of the one, true God, the God of Israel, what emerges is a story of the God who is Father, Son, and Holy Spirit—there all along, but finally and fully known through this new covenant, this new promise ratified by the blood of Jesus. I know my first point this morning has been to help you understand why Abraham was so important to Paul, so that as we get into his main argument we’ll understand why he says the things he does, but I also want to encourage you to think—or maybe I should say to trust—in the story. The next time you recite the creed, don’t just think of it as a set of theological propositions that need to be affirmed to be orthodox. Think of it as the great story of God and his people, the great story of his promises and his faithfulness, the great story that reveals the redeeming grace of Father, Son, and Holy Spirit, the great story that ultimately ends with the world finally set to rights and proclaiming his glory—the great story into which we have been baptised—the great story in which we live.
Let’s pray: Almighty God, our gracious Father, who called Abraham out of the darkness and promised to make his family a light to the nations, we pray that as we recall the great story of your faithfulness, and especially how you have fulfilled your promises in Jesus and the Spirit, teach us to trust in and to find our assurance in you, not just in our heads and with our brains, but as we commit our whole selves to you and become, ourselves, part of the great story of your faithfulness. Amen.
