After finishing the first week, today’s reading felt almost strangely short. Genesis 25 does not have the scale of the flood, the violence of Sodom, or the unbearable tension of Abraham walking Isaac up the mountain. Most of it is names, deaths, descendants, and the beginning of another generation. But maybe that is exactly why I needed to slow down.

Week One began with the question:

How does humanity come home?

Genesis still has not answered that. If anything, the first week showed me how deep the problem really is. Human beings know God and still disobey Him. We survive judgment and carry the same heart into the new world. We build Babel. We manipulate. We use people. We lie because we are afraid. We try to manufacture what God has promised because waiting feels unbearable.

So I began Week Two carrying another question:

Can human beings trust God enough to stop grasping?

And Genesis 25 gave me an answer I did not expect.

Not necessarily through Abraham.

Through his children.

Genesis 25 opens with something that initially frustrated me:

“Abraham again took a wife, and her name was Keturah.”

— Genesis 25:1, NKJV

Then 1 Chronicles later refers to Keturah as Abraham’s concubine.

At first my reaction was basically: Abraham, seriously?

After everything with Sarah. After Hagar. After all the damage created when another woman’s body became part of Abraham and Sarah’s attempt to solve the promise. After finally reaching the point where Abraham could walk up a mountain and say, “God will provide,” he now has another woman and more children.

But this is one of those places where I need to let the text correct my first emotional reaction.

Genesis calls Keturah Abraham’s wife. Chronicles calls her his concubine. In the ancient world, those categories could overlap differently than they do in modern language. A concubine was generally a woman with a recognized relationship to a man but a lower social and inheritance status than a primary wife. That does not make her a prostitute, and Scripture does not describe her that way.

It is also important that Sarah is already dead. Abraham remarrying after Sarah’s death would not itself be immoral.

So what exactly am I supposed to do with this?

Maybe the answer is simply not to force Genesis to answer a question it does not answer.

It does not tell me why Abraham had more children. It does not tell me he was trying to create backup heirs in case something happened to Isaac. It does not tell me he thought more children would somehow multiply the covenant blessing. It does not tell me whether he was lonely, whether this was culturally expected, or whether any particular motive was driving him.

I can imagine all of those explanations. I cannot call any of them Scripture.

That has become one of the hardest disciplines of reading this way: sometimes the Bible tells me what someone did and refuses to give me the psychological explanation I want.

Still, Genesis has already given us a pattern for marriage. Back in the beginning, before human beings began rearranging everything, we were shown the man and woman becoming one flesh. Then Genesis repeatedly shows increasingly complicated households—multiple wives, concubines, rivalries, inheritance disputes—and the stories rarely become simpler because of it.

The Bible does not have to insert a sentence after every action saying, God approves this or God disapproves this.Sometimes the consequences speak.And sometimes the text simply records what happened.

That is something I think Christians can miss when reading the patriarchs. Abraham is not presented as righteous because everything he ever did was righteous. God’s faithfulness to Abraham does not turn Abraham’s biography into an instruction manual. The Bible is remarkably comfortable allowing faithful people to remain complicated. Then Abraham dies.

“Then Abraham breathed his last and died in a good old age, an old man and full of years…”— Genesis 25:8

He is 175 years old. And I found myself almost objecting to the phrase “full of years.”

After everything? After Egypt? After the deception? After Hagar? After Sarah’s treatment of her? After all the moments where Abraham’s fear hurt other people?

Yes. After everything.

That does not mean Genesis has suddenly declared every action good. It means Abraham’s life is finished. And maybe that is uncomfortable because I prefer clean endings. I want a character to reach the lesson, become permanently transformed, and never stumble into anything morally complicated again. But actual human beings rarely work like that.

Abraham grew enormously.

The man who once tried to manufacture God’s promise eventually reached a mountain and trusted God with Isaac. The man who lied to foreigners out of fear later confronted Abimelech openly and made peace. The man who spent years trying to secure his own future eventually died owning almost none of what God had promised.

Growth was real. Perfection was not. Maybe that matters because grace does not require God to pretend Abraham was better than he was.

God can call a man, discipline him, grow him, use him, keep promises to him, without rewriting his failures.

Then comes one of the quietest moments in the chapter:

“And his sons Isaac and Ishmael buried him in the cave of Machpelah…”— Genesis 25:9

Machpelah. The cave Abraham purchased after Sarah died. The first permanent piece of the promised land Abraham legally possessed. The place where Sarah was buried. Now Abraham joins her there.

But what struck me most was not the grave. It was the two men standing beside it.

Isaac and Ishmael.

Genesis does not tell me they became best friends. It does not tell me they spent years visiting each other or that every wound between their households had disappeared. So I cannot write a reconciliation story Genesis never gives me.

But they buried their father together. That is enough to matter. Because Genesis began human history with another pair of brothers. Cain and Abel. Cain could not tolerate the difference between them. Jealousy became murder. Now we have another family where one brother holds the covenant inheritance and the other does not.

Isaac received what Abraham had. Ishmael did not. And yet Abraham’s story does not end with one brother murdering the other over the inheritance. They stand together at their father’s grave. That feels important. Abraham had given everything he had to Isaac, while the sons of the concubines received gifts and were sent eastward. The inheritance was clearly unequal because the covenant line was clearly through Isaac. 

Yet Genesis does not show Ishmael returning with an army to claim what he believes should have been his. Instead, when Abraham dies, Ishmael comes home to bury him.

Maybe that is all we are allowed to say. But it is a much quieter ending than I expected.

Then Genesis turns toward Ishmael’s descendants. This is another section I could easily have skimmed before beginning this project. Names. More names. Places. Tribes. 

But after everything God said about Ishmael, the genealogy becomes evidence. God promised Hagar and Abraham that Ishmael would live and multiply.

Now Genesis tells us Ishmael had twelve sons:

“Twelve princes according to their nations.”— Genesis 25:16

God meant what He said. Isaac was chosen for the covenant. That did not make God’s promise to Ishmael fake.

Yesterday Ishmael was lying beneath a shrub while his mother expected him to die. Now he has sons, tribes, settlements, descendants. The boy who almost died in the wilderness became the father of peoples. 

That is one of the things I am beginning to notice about these genealogies. They can look boring because we are reading names. But each name represents a promise surviving another generation. The genealogy is sometimes the receipt. God said someone would live.

Then several chapters later, Scripture gives you the names of the people who exist because they did.

And 1 Chronicles 1:28–34 later repeats these family lines—Isaac, Ishmael, Keturah’s descendants, Esau—almost as if Scripture is pulling the camera backward and saying:

These were not merely family arguments inside tents. These became history. 

That idea keeps getting larger. Abraham sees sons. God sees generations. Hagar sees a dying boy. God sees twelve princes. Rebekah will soon feel two children fighting inside her. God tells her she is carrying two peoples. We experience our lives one moment at a time.

Scripture keeps showing God working across generations.

Then Genesis moves from Abraham to Isaac. And this may have been the part of today’s reading that hit me hardest.

Isaac marries Rebekah at forty.

Then:

“Now Isaac pleaded with the LORD for his wife, because she was barren…”— Genesis 25:21

Rebekah cannot have children. Again. Another barren marriage. Another promised family. Another situation where the future seems unable to happen naturally.

And immediately I thought about Abraham. God promised Abraham descendants. Sarah could not conceive. Years passed. Eventually Abraham and Sarah stopped waiting and created an alternative solution through Hagar. That decision produced an actual human being whom God loved and protected. But it also produced pain that lasted for years.

Now Isaac faces essentially the same test.

His wife is barren. What does Isaac do? He prays.

That is all Genesis gives me. No second woman. No concubine introduced to solve the problem. No surrogate arrangement. No alternate heir.

At least up through verse 26, Isaac simply pleads with God for his wife. And then I noticed how long he waited. Isaac was forty when he married Rebekah. He is sixty when Jacob and Esau are born.

Twenty years.

Twenty years of waiting. That makes the verse much heavier. “Isaac pleaded with the LORD” is easy to read in five seconds. Isaac lived the problem for roughly two decades.

And this is where Week Two’s question suddenly comes alive. Can human beings trust God enough to stop grasping?

Abraham faced barrenness and eventually grasped. Isaac faces barrenness—and prays.

I do not want to idealize Isaac too early. I have barely started his story. He may disappoint me tomorrow. Genesis has taught me not to canonize someone’s personality after one good chapter. But in this particular moment, the contrast is difficult to ignore.

Maybe Isaac learned something from his father. Genesis does not explicitly say, Isaac remembered Hagar and decided never to repeat Abraham’s mistake. So I cannot claim that. But Isaac grew up inside the consequences of Abraham’s decision. He knew Ishmael existed. He knew his family history. He eventually stood beside Ishmael to bury their father.

Whatever Isaac knew emotionally about all of that, the narrative itself places two very different responses beside one another.

Abraham + barrenness: eventually, a human workaround.Isaac + barrenness: prayer.

Maybe one of the hopeful things Genesis is beginning to show me is that inheritance does not have to mean repetition.

Children receive more than property from their parents. They inherit stories. Habits. Wounds. Ways of responding to fear. Examples worth copying. Examples worth refusing.

Isaac inherited Abraham’s wealth. He inherited the covenant. He inherited the land promise. He inherited the story of a father who could trust God enough to place him on an altar.

But he also inherited the story of a father who once became so impatient that another woman and another child were pulled into the consequences.

The question is not simply:What did Abraham leave Isaac?It is:What will Isaac choose to carry forward?

Maybe part of growing beyond the generation before us is learning to receive what they did well without baptizing everything they did wrong.

Our parents can teach us through obedience. They can also teach us through consequences. 

Sometimes the lesson a father gives his son is:Do what I did.Sometimes the lesson is:Never do what I did here.

Then something else happens that I loved. Rebekah finally becomes pregnant, but the pregnancy is difficult.

“But the children struggled together within her…”— Genesis 25:22

She asks:

“If all is well, why am I like this?”

And then Scripture says:

“So she went to inquire of the LORD.”

That stood out to me. Rebekah is not merely standing behind Isaac while Isaac has the relationship with God. She asks God herself. And God answers her.

“Two nations are in your womb,Two peoples shall be separated from your body;One people shall be stronger than the other,And the older shall serve the younger.”— Genesis 25:23

Again: Nations. Genesis started with a single couple in a garden. Now everything is expanding. Ishmael’s twelve princes. Isaac’s descendants. Two nations inside Rebekah. The promises are moving outward.

But there is also another reversal.

The older son would normally be expected to carry special status. God tells Rebekah before the children are even born: The older will serve the younger.

Human custom says one thing. God’s purpose will move another way. That sounds familiar already.

Human beings keep trying to determine who should receive what. God keeps refusing to be controlled by our systems of importance.

Then the boys are born.

Esau comes first, described as red and “like a hairy garment all over.” I almost read that as “so Esau was basically a redheaded baby,” but that would go beyond what the text actually says. He is reddish in appearance and unusually hairy. That is what Genesis gives me. Then Jacob comes out holding Esau’s heel. Before either boy has spoken a word, the relationship between them has already been marked by struggle.

Rebekah felt them fighting before birth. Jacob enters the world gripping his brother’s heel. And God has already told her that these two children will become two peoples. Again, something enormous is hiding inside something ordinary.

To Rebekah:A painful pregnancy.To history:Two nations.

That may actually be the theme of this short reading. Genesis 25 feels small because almost everything important is still beginning. Abraham dies. Isaac and Ishmael bury him. Ishmael’s sons become princes. Isaac prays for his barren wife. Two babies are born. Chronicles records names. Nothing feels as dramatic as yesterday’s mountain.

But maybe that is how most of God’s promises actually move through history. Not always through fire from heaven. Sometimes through funerals. Pregnancies. Prayers. Births. Names written into genealogies. People dying before they see what their lives become.

And that brings me back to Abraham. I started today irritated with him. Part of me still is. There are things about his life I do not admire, and Scripture does not require me to pretend otherwise.

But maybe Abraham’s greatest legacy is not that Isaac inherited a flawless model of faith. He inherited a truthful one. He saw what trusting God looked like. He also saw what happened when his father stopped trusting. And maybe Isaac did something Abraham struggled to do:He waited.

Twenty years. No alternate heir is mentioned. No second plan. He pleaded with God. And God answered.

So I think today gave me the first real response to the question I am carrying into Week Two:

Can human beings trust God enough to stop grasping?

Maybe. Not perfectly. Not permanently. But maybe one generation can learn something the previous generation learned the hard way.

Abraham spent much of his life trying to make God’s promises happen. Isaac encounters the same kind of impossibility—and prays.

Maybe maturity is not inheriting perfect people. Maybe it is learning how to inherit faithfully from imperfect ones.

Keep the obedience. Learn from the failure. Receive the promise. Refuse the grasping.

And trust that the God who kept His word to Abraham and Ishmael—

can keep His word to Isaac too.
