In my Abraham series, I have included writing tips that are illustrated in Abraham’s stories. We came to the end of his story in my last post. This post continues that series, but it is all for writers. How can these stories help you improve your technique?
The challenge for any writer of fiction is to tell a good story that keeps the reader/audience’s attention from beginning to end. There is an unspoken agreement between the storyteller and the audience: They will suspend their disbelief for the duration of the story, as long as you keep it believable to them. The trick is to know what is believable and what is not to your audience. Or perhaps, whether you have made it believable to them.
As fiction writers, we sometimes create moments when we could easily lose the reader, because we stretched their suspension of disbelief too far. So we should always consider whether we have succeeded in making that moment of “impossible” believable. In that regard, I think we can learn a few things from the author of this saga I’ve been following for the last several weeks.
The author/editor of Abraham’s saga was most likely not so much an author as an editor. These stories had circulated orally for centuries before they were written down in what we call today the book of Genesis. So instead of creating these stories out of nothing, the writer decided to put the individual stories together into one narrative. It’s a little easier when you’re working with stories your audience is already familiar with and has accepted as part of their history. Still, there are moments when the author has to overcome the disbelief any rational person would have. Perhaps the greatest of those moments is how and when Isaac is born.
Here it is to review.
The LORD dealt with Sarah as he had said, and the LORD did for Sarah as he had promised. Sarah conceived and bore Abraham a son in his old age, at the time of which God had spoken to him. Abraham gave the name Isaac to his son whom Sarah bore him.
And she said, “Who would ever have said to Abraham that Sarah would nurse children? Yet I have borne him a son in his old age.”
(Gen 21:1-3, 7 NRS)
Remember, Abraham is one hundred, and Sarah is ninety-one. How did the author make that moment believable to his original audience?
Know Your Readers’ Expectations
The original readers of this story probably had heard these accounts of Abraham and his family before, but not exactly the way the author presented them in this written account. This author wanted to collect all those disjointed stories into one narrative. In sewing together these different patches, sometimes the seams show. While there are a few plot holes, his audience forgave him that. I think that is because,
- He ordered the individual stories in a way he knew would be satisfying to his audience. This is why it is good to know how to plot. The story arc this author used was familiar to his audience.
- Each genre carries certain expectations. These stories primarily come from the Origin Story genre, and they fit the expectations of that genre.
Expectations and believability for the reader/audience often depend on the genre. In a murder mystery, for example, the audience expects that there is a murder, and by the end of the story, the murderer is revealed and caught. In a fantasy, the audience expects there will be magic, sword battles, and mythical creatures. A dragon as the murderer in a modern mystery would not be believable. But in a fantasy? No problem. Knowing what your audience will accept, and what they won’t, is the first step to making your story believable to them.
Use Foreshadowing, Subtly
The author is skillful in how he uses foreshadowing. He doesn’t give away too much too soon. He used the genealogies to create just enough uncertainty that the reader could think they might be able to have a son, even at their advanced age, before telling us they were too old. God hinted to Abraham his son Ishmael would fulfill his destiny apart from him before it happened. If Ishmael was not the child of the promise, then who? His heir would come through Sarah.
And beyond this story, Isaac’s role in the story foreshadows many things that will happen later in the Torah.
- Meetings at a well that lead to marriage (Jacob and Moses).
- Wives who have difficulty conceiving and bearing a child (Rebekah and Rachel).
- Wives giving handmaids to their husbands to conceive and bear a child (Rachel and her handmaid, Zilpah).
- Parents’ favoritism or rejection leads to dysfunction among siblings (Jacob and Esau, Joseph and his brothers).
- Covenants that involve name changes (Jacob to Israel).
Foreshadowing, when used well, will help the reader/audience maintain their suspension of disbelief and accept the “impossible” as the natural outcome of your story.
Show the Heroes’ Humanity
When God appears to Abraham at ninety-nine years of age and says he will have a son with Sarah, who was ninety, “He did not weaken in faith when he considered his own body, which was already as good as dead (for he was about a hundred years old), or when he considered the barrenness of Sarah’s womb. No distrust made him waver concerning the promise of God, but he grew strong in his faith as he gave glory to God” (Rom 4:19-20 NRS).
That’s the “hero of the faith” version, which is totally unreal and not how the story tells it originally. How did Abraham really react? “Abraham fell on his face and laughed” (Gen 17:17 NRS), and that’s how any human with a brain would have reacted. Sarah also laughed, and who could blame them? Any of us would have laughed at that as well. They know as well as we do this is impossible.

When the promise is fulfilled, we see Sarah’s humanity in her joy as she holds her newborn son. She lets us know everything she went through to get to this moment was worth it. The author shows their humanity in so many other ways as well. In contrast, Paul presents them as believing God, and it being accounted to them as righteousness (Rom 4:3, 9; Gal 3:6), as if this were a 24/7/365 reality. God said it. They believed it. And that settled it, once and for all.
That is not usually what a life of faith looks like, and Abraham and Sarah are prime examples. When God commanded, they obeyed. But for years, they struggled to understand what God really wanted from them. They said things like, “How do I know this is true?” (Gen 15:8). God said things that made them laugh. They wavered between belief and disbelief in the long time between promise and fulfillment.
Another thing to remember is even heroes have faults. I have talked about failings in the character of both Abraham and Sarah. Whatever character flaws your characters have, you don’t need to hide them. They make your characters more human. Some of the most fascinating characters are those who infuriate us one moment and inspire us the next.
Prepare the Reader for the Big Moment
Abraham and Sarah are going to have a son. That is the most crucial event of this story. It has to happen, and it’s impossible. Everyone knows it is impossible. So how can the reader believe it when it happens? In this case, they are all descendants of Abraham and Sarah, so they know it happened. The big question they had was not if but how.
Getting back to genre expectations, origin stories often involve interactions between human heroes and divine beings. In this case, when God announces the big moment to Abraham, God has already appeared to him twice. God has made big promises to him, but none of them can come true unless he has a son with Sarah. That is the one promise God absolutely must fulfill in this story. The rest can happen later, but this has to happen now.
The author has helped prepare the audience for this moment by how God has guided Abraham thus far. God only hinted at the promise before. They did not understand what God meant at first. Then, at this crucial moment, God promises much more specifically to both Abraham and Sarah. And when they actually did “weaken in faith” and “waver concerning the promises of God” momentarily, God made sure there was no misunderstanding this time. God made specific promises, not that this will happen sometime in the future. It will happen “by this time next year.”
They had hoped for this sooner. They had given up hope of it ever happening. But God keeps God’s promises at the time God chooses. And now, I, the angel of the LORD, am telling you, this is the appointed time.
Bring in an All-Powerful God
Origin stories often use a technique called Deux ex Machina, literally “God of the Machine.” Just when everything is lost, some divine being—a god, goddess, angel, etc.—swoops in and fixes everything. Today, that is considered an amateur move. This author avoids that pitfall, however, by having God appear to Abraham before this and make promises that are not specific enough. The audience knows more than Abraham and Sarah. They know God wants this to happen, even when Abraham and Sarah have given up on it.
This is God’s third visitation to Abraham, so the big pronouncement does not come out of the blue. It is consistent both with the previous appearances and what God has promised before. “I am El Shaddai,” God tells Abraham this time (Gen 17:1). That is a name Abraham has not heard before, so that alerts him and us the story is about to take an important turn.
This particular name is usually translated “God Almighty.” Another meaning I found was “God the Overcomer,” meaning that God can and will overcome any obstacles when it’s time to fulfill a promise. In this case, the obstacles were pretty significant. To review,
- Though they were still in good health, the text makes it clear they were not having sex anymore. Not because they were unwilling, but because they were both unable.
- The deadness of Sarah’s womb. She never had a child nor got pregnant, even when she was young.
- Even if somehow God made her barren womb fertile, Abraham still had to rise to the occasion. That hadn’t happened in years, because (D’uh!) he was nearly a hundred years old.
But God addressed those objections even before Abraham had a chance to raise them by saying, “I am the God who overcomes every obstacle that exists and any that will exist.” And when God tells Sarah, “Is anything too wonderful for the LORD?” that signals to her and the audience this is going to happen, in spite of any obstacles that would normally prevent it.
If your type of story allows it, you can bring in a god, goddess, angel, or superhero to make whatever needs to happen happen. Just be sure you’ve set the reader up to accept it, so you don’t look like an amateur.
Have Your Heroes Make Missteps along the Way
It was twenty-five years from when God promised Abraham a son of his own issue to when Sarah gave birth to Isaac. When God first promised, Abraham had no problem believing it. He was still a “young man” of seventy-five. He and Sarah still were active in the bedroom. Sure, she was sixty-six and had not yet had a child. But if God promised he would have a son, he would have a son. God would do God’s part in fulfilling the promise as long as they did their part (keep having sex).
But after ten more years of trying, still nothing. Sarah concluded if Abraham was to have a son of his own issue, it would have to be through another woman. So she convinced her husband to go in to her handmaid, and he had a son, Ishmael. On the one hand, it was a misstep. They stopped believing that they would have a son together. On the other hand, this misstep was not a product of doubting the promises of God.
God had not yet promised that Abraham’s heir would come through Sarah. God only promised that he would have a son of his own issue. Sarah was seventy-six before she resorted to bringing in a surrogate. She had no reason to believe at that point there was any other way. They gave up only after giving every reasonable chance, and then some, for God to make it happen. And that makes the big moment even bigger.
Heroes Recognize the Moment When It Comes, Even after Hope Is Lost
God shows up again when Abraham is ninety-nine and says now is the time, and Abraham is elated. He jumps for joy that the hope he had been living for was about to happen. Sarah is ninety when God tells her this is it, and she forgets the deadness of her womb and her husband’s flesh. She believes immediately and does not doubt it, because God said it. You know I’m kidding, right?
Sarah and Abraham react the same way at first. They laugh, not for joy, but because the very idea is utterly ridiculous. They had given up on this happening years ago. If God wanted this to happen, God should have done it before now. But note that God did not say, “You don’t believe me? Then forget it. I won’t do this for you, because you doubted my word.”
Instead, God makes it clear this is no joke. For Abraham, God repeats the promise and lets him know Ishmael is not forgotten. God will make him a great nation as well. But his heir would come through Sarah, “by this time next year.” Then God appears again and repeats it so Sarah can hear.
Last time God promised this, God was totally vague about how and when it would happen. This time, God is totally clear. You, Sarah, will have a son by this time next year. And God says, “Is anything too wonderful for the LORD?” When God makes a promise, nothing is too wonderful to prevent God from fulfilling it. God even incorporates their laughter into the promise by saying, “You will name him, ‘He laughs.’”
How did they recognize now was the time? God finally told them so. But did they believe immediately? No, they laughed. Even if they did, that was not enough to make it happen. If Abraham was not able, he was not able. If Sarah’s womb was barren, it was barren. There was nothing either of them could do to change it. The only thing they could do at this point was be open to the possibility. And that was all God required of them.
And there was one other way they recognized it was time. After all God did to tell them to be ready, there was one particular sign they needed to see. One day, for the first time in years, Abraham was able to get it up. Sorry for being crude there, but we’re adults. We know without that, there was no way God’s promise could be fulfilled. Somehow, God brought both their dead flesh back to life. Sarah conceived and bore a son at ninety-one, and they named him Isaac (“he laughs”).
Irony Makes for Memorable Stories
Sarah laughed again (Gen 21:6-7), but the meaning of her laughter changed from disbelief to joy. Isaac’s name means “he laughs,” to remind both Abraham and Sarah they once thought this was impossible. When a story turns in a way either the characters or audience doesn’t expect, that creates irony. I’ve talked in previous posts about how the author uses irony effectively. The irony happens when they go from laughing at God to laughing with God. For the Israelites who first heard this story, the irony was a reminder that their very existence was once considered impossible, just like Isaac’s.
As I’ve examined how the author used irony in Abraham’s story, I was struck thinking how many of my favorite stories, the ones I come back to time and again, make effective use of irony. And it is not just in this story. Across many different authors and thousands of years going back to when these stories were first told around campfires, the stories in the Bible use irony as much as O. Henry. When it comes to making the impossible believable in your stories, irony says to the reader, “I know you didn’t expect this. I know you thought this was impossible. Now, I just showed you it’s not.”
From generation to generation, this and all the stories in the Bible have been passed down, because they are so memorable. They make us believe the impossible is possible. Or if not believe, they at least make us question whether “impossible” really is an absolute term. They open us, like Abraham and Sarah, to possibilities we had once dismissed. I think one reason is because this author and all the others represented in the Bible saw and highlighted the irony in the stories they passed down to us.
Whether or Not This “Really Happened” Really Doesn’t Matter
Anne Rice is a bestselling author who first became famous for her vampire novels. After a conversion, she turned her attention for a while toward religious fiction. In an interview, she said she used to have readers call her at 2:00 AM, begging her to reassure them that her vampires really were made up. In fiction, it doesn’t have to be real. It has to be believable.
Perhaps the same can be said of Abraham’s saga. I’m not saying it’s fiction. I’m saying it is an origin story. The reason we study origin stories is not to learn historical fact so much as to learn about the personality and culture of the people who produced those stories. What experts have found is they often began with some historical event. Over time, legends and myths grow around that event. Homer’s Iliad, for example, was once thought to be pure myth. Then archaeological excavations of the city of Troy revealed it was once a prosperous city that underwent siege and destruction around the same time as Homer said.
That does not prove that everything it says about the gods and goddesses and Helen’s abduction/escape launching a thousand ships all “really happened” as well. But it appears the whole saga began with a real event. Experts still study the Iliad to learn about the character of the people who produced those stories.
The Hebrew Bible was written primarily in what they called the land of Canaan. However, those authors were familiar with Babylonian myths. They showed some influences from ancient Sumerian and Akkadian sources. The story itself says Abraham immigrated to Canaan from cities in Mesopotamia. Could that point to a historic migration of people from Mesopotamia who eventually became part of the Hebrews and Israelites? He left the city and became a nomad and herder, so perhaps they were herders as well.

What is most important in origin stories is usually the moral and theological lessons they teach. What lessons did this author want to teach?
- God called their ancestors to this land with the intention that they would inherit it.
- God chose them to bring justice, righteousness, and the fear of God to this land.
- God preserved offspring through their ancestors so that through them, at the right time, the Messiah would come into the world.
- Remember all of God’s promises, and make sure your children know them. One day, they will all be fulfilled.
- Remember “nothing is too wonderful for the LORD” when it is time to fulfill a promise.
- Do not despise the Ishmaelites, because God had a purpose for them as well.
So what about your WIP?
Do you know the expectations of your genre? Are you meeting them? If you want your readers to believe something impossible, how are you going to make it believable? If you do it right, they should see the “impossible” become “inevitable,” just as it was inevitable that Sarah have a son at the tender age of ninety-one.
