Cain & Abel

I was really tickled by the title my favorite Old Testament scholar gave to his treatment of the story of Cain and Abel. He called it “The Brother Problem”.

If you’ve ever had a sibling, I’ll bet you can resonate with that title, too.

It’s tempting to make a sermon about Cain and Abel just a bunch of stories of how brothers antagonize each other, but I’m not going to do that today…okay maybe just one.

One time my brother made me think I was dead. I was like 5 years old, on vacation with our cousins from Argentina seeing waterfalls in North Carolina, and he came up with a fun game for the three of them that when I came into the motorhome, they should pretend they couldn’t see or hear me and also talk about how sad it was that I fell off the waterfall and drowned.

It worked. He made me doubt my existence.

The brother problem indeed.

Now that’s the kind of brother problem most of us are familiar with. The story in Genesis is about a much deeper kind of brother problem.

It’s not a fable. No matter how dim your view of humanity is… no one ever had to be told that murdering your brother was wrong. That’s always been an obvious no-no.

“But Gooooddddd… you never specifically tooooollld me not to…”

So what is this story?

There’s actually a lot going on here. If you haven’t heard or read the story in a while, here’s the fast version.

Adam and Eve had two sons: Cain and Abel. Abel became a shepherd, Cain a farmer. They brought sacrifices from their work to God, but God didn’t like Cain’s sacrifice and this really ticked Cain off. God gives Cain a little pep talk, but rather than deal with his feelings, Cain kills his brother instead. God comes looking for his brother and asks Cain about it, who says, “I don’t know! Am I my brother’s keeper?” To which every decent person ever answers, “YES!”

God says that he already knows where Abel is because his blood is crying out to him from the ground, and then punishes Cain, who now gets upset again, not because he realizes how wrong he was, but because “What if someone does to me, what I did to Abel?” That would be a PROBLEM. And God being God, he marks Cain so that people know not to mess with him. And Cain leaves the presence of God forever.

At its heart, this story isn’t about murder. It’s about what happens when people believe they’re not responsible for each other.

The plot of the story is good, but it really shines in the details of the verses. So let’s get into those together.

Genesis 4:1 Now the man knew his wife Eve, and she conceived and bore Cain, saying, “I have produced a man with the help of the Lord.” 2 Next she bore his brother Abel.

Cain is a strong name. It’s connected to the Hebrew word for “getting” or “acquiring.”

Abel sounds like hebel, which is breath or vapor…something fleeting.

Now Abel was a keeper of sheep, and Cain a tiller of the ground.

Here’s where the wheels start to come off.

Already here we see division. Specifically division of labor. One brother works the soil, the other keeps the flocks. That’s how communities survive. But difference leads to comparison real quick. Which if you’re unaware of it, often turns into resentment.

But it’s not just division that divides these brothers. Here comes an even worse offender…Religion

3 In the course of time Cain brought to the Lord an offering of the fruit of the ground, 4 and Abel for his part brought of the firstlings of his flock, their fat portions.

Now God hasn’t asked for sacrifices yet in Genesis, which is one of those clues that tells us that these fragments were sewn together much later, but don’t let that distract us from the story.

And the Lord had regard for Abel and his offering, 5 but for Cain and his offering he had no regard.

Now maybe this is because of the quality of their sacrifices. Or maybe it’s because God’s choices don’t always make square with our sense of fairness.

Either way, one of the first things the Bible shows us about religion is how dangerous it can be. It really is like a drug and some people should handle it a lot more carefully than they do.

Religion can activate the best parts of us, but it can also stir up our worst. That’s what it did to Cain.

So Cain was very angry, and his countenance fell.

He starts walking around like Charlie Brown. But one of my favorite scholars suggests that he’s doing that because God pulled the football away from him.

Walter Brueggemann writes,

“The trouble comes not from Cain, but from Yahweh, the strange God of Israel. Inexplicably, Yahweh chooses-accepts and rejects. Conventional interpretation is too hard on Cain and too easy on Yahweh. It is Yahweh who transforms a normal report into a life/death story for us and about us. Essential to the plot is the capricious freedom of Yahweh. Like the narrator, we must resist every effort to explain it.

The rejection of Cain is not reasoned but is a necessary premise for the story. Life is unfair. God is free.

God presents himself not quite enemy, surely not friend, certainly not advocate, finally leaving it fully "up to us.” (Interpretation, Vol. 1)

By rejecting Cain’s offering like this, God creates a crisis. And then… God hands the crisis right back to Cain.

6 The Lord said to Cain, “Why are you angry, and why has your countenance fallen? 7 If you do well, will you not be accepted?

In other words… Cain still has a choice.

He’s not doomed. He can still do the right thing.

That’s important, because sometimes we read Genesis 3 and think humanity is just broken beyond hope after that. But Genesis 4 doesn’t tell the story that way.

Cain isn’t helpless. He’s free.

Even if it feels like God has put us in an crisis, we’re still responsible for what we do next.

And if you do not do well, sin is lurking at the door; its desire is for you, but you must master it.”

Notice how God describes sin here. Not as simply breaking a rule, or a bad decision sitting in your mind going “Pick me!”.

Sin is like a lion crouching outside the door… waiting. The stakes are high. The anger and resentment building inside Cain aren’t just harmless feelings that will just pass if he vents a little. They have a power of their own.

Sin wants Cain. It hungers for him.

And once that force gets loose in the world, it doesn’t just destroy the victim. It destroys the perpetrator too.

But notice something else in what God says.

After warning Cain about the danger… God says something remarkable.

“You must master it.”

In other words, the lion doesn’t automatically win.

There’s still a fight to be had.

Lion Tamers

I keep a picture in my office of a lion tamer. He’s kneeling there in the cage with a massive lion… armed with nothing but a chair, a whip, and a whole lot of confidence.

And if you’ve ever seen those acts, you know something about that scene. The lion tamer isn’t stronger than the lion. Everyone knows that if the lion decides the show is over… it’s over.

But somehow, with courage and awareness and a whole lot of practice, the tamer can keep the lion under control.

That’s the image Genesis is giving us here.

Sin is powerful but it doesn’t have to be in charge.

The lion can be mastered.

But the tamers have to know themselves well enough to recognize when they can get in there with a whip and chair, and when it’s time to call in sick, or even run away. All of those options are how lion tamers live to see another day.

Cain didn’t do that. And the story shows what happens because of that.

8 Cain said to his brother Abel, “Let us go out to the field.” And when they were in the field, Cain rose up against his brother Abel and killed him.

And that’s it.

All that warning. And in one short sentence… Cain kills his brother.

The first murder in the Bible happens almost casually. Which is probably the point.

So before we move on, let’s take a moment and sit with what just happened.

You know, we’re so used to hearing things like this, aren’t we?

Violence surrounds us all the time. It’s on the news so much that we stop hearing it. It’s in the movies we watch. It’s in the shows we binge. We’ve heard so many stories of people killing each other that sometimes it barely registers anymore.

9 Then the Lord said to Cain, “Where is your brother Abel?”

Which echoes the way that God called to Cain’s parents in the Garden. Where are you becomes where is your brother.

God is giving Cain a chance to tell the truth, to take responsibility and say, “I did something terrible.” But Cain doesn’t do that. Instead,

He said, “I do not know;

Which of course isn’t true. Cain knows exactly where his brother is. But some people have a hard time seeing the truth about themselves. We all do, of course, but some folks…boy…

Some of you were raised by a narcissist, so this whole “I don’t know” thing is old news. But we’re all dealing with a narcissist, and we all know how “I don’t know” turns into:

That didn't happen.


And if it did, it wasn't that bad.


And if it was, that's not a big deal.


And if it is, that's not my fault.


And if it was, I didn't mean it.


And if I did, you deserved it.

And when that stops working… people like Cain try to make the conversation about philosophy instead of morality. They stop talking about what they did… and start talking about what responsibility even means. So Cain asks,

Am I my brother’s keeper?

YES! Why is that even up for debate? What kind of a person even asks a question like that?

A person who just murdered his brother for one. Or someone who wants to keep the option on the table for another.

People only ask that question when they’ve already decided the answer should be no.

God answers Cain’s question in a way that leaves no room for debate.

10 And the Lord said, “What have you done? Listen, your brother’s blood is crying out to me from the ground!

In the Hebrew understanding of the world, blood is sacred.

It’s life. And life belongs to God.

That’s why Israel’s law forbids people from consuming blood. When animals were sacrificed, the blood was poured back into the earth… returned to God… because life belongs to God.

So when Cain spills Abel’s blood, he hasn’t just hurt his brother. He has violated something precious that belongs ultimately to God.

That blood doesn’t disappear. It cries out. It testifies. God hears it. “Your brother’s blood is crying out to me from the ground.”

And if God could hear Abel’s blood crying out from the ground…

imagine what God must hear right now. I wonder if God can hear anything else.

God hears every drop, and is keeping account of who spilled it.

So Cain’s trial doesn’t last long. He can’t distract God from what he did. God moves quickly to the sentencing. Justice is not delayed or denied when God is on the ground. Wouldn’t it be something if the world worked like that? At least here it does.

11 And now you are cursed from the ground, which has opened its mouth to receive your brother’s blood from your hand. 12 When you till the ground, it will no longer yield to you its strength; you will be a fugitive and a wanderer on the earth.”

And then Cain speaks. But pay attention to what he doesn’t say.

He doesn’t apologize. He doesn’t mourn his brother. He never even confesses what he did.

The only thing that bothers Cain… is the punishment.

13 Cain said to the Lord, “My punishment is greater than I can bear! 14 Today you have driven me away from the soil, and I shall be hidden from your face; I shall be a fugitive and a wanderer on the earth, and anyone who meets me may kill me.”

And if I was God…and let’s all be thankful that I’m not, I would have said, “Yuh-huh!”

You made the world this way, Cain. Now you get to live in it.

But that’s not what God does.

Because the God of this story is a God of grace.

A God who still sees the good that might yet be possible… even in someone like Cain.

And that might make us uncomfortable, because we really want Cain to get what’s coming to him. But he gets the chance to make living amends and we’ll see next week how he does with that.

But we also need to hear that when the Bible talks about grace for the Cains of the world… it’s not talking about some other group of people.

It’s talking about us.

All of us have hurt someone.
All of us have chosen resentment instead of love.
All of us have tried to change the subject when the truth got too close.

The same God who judges Cain… is also the God who refuses to give up on him.

And on us.

15 Then the Lord said to him, “Not so! Whoever kills Cain will suffer a sevenfold vengeance.” And the Lord put a mark on Cain, so that no one who came upon him would kill him.

16 Then Cain went away from the presence of the Lord and settled in the land of Nod, east of Eden.

And that’s how the story ends.

But did it have to go that way?

What If?

What if, instead of bottling up all that resentment…
instead of letting it grow and fester inside of him…

What if Cain had just talked to his brother?

What if he had said,

“Hey Abel… I need to tell you something.
It makes me crazy that it seems like God likes you better than me.”

And maybe Abel would have said, “Yeah he sure does cause he’s got good taste!”

And then Cain could have killed him anyway but it would have been justified.

But I don’t think that’s how it would have gone. I think Abel would have said,

“Cain… you’re my brother. Come sit down. Let’s talk about it.”

And maybe the first brothers in the Bible just sit down and have an honest conversation. It could have been good.

But Cain never spoke to Abel. He lets the resentment grow instead. So if you have an Abel in your life…talk to them. Or at least talk to me or Megan about them. But don’t let that resentment build.

Your story doesn't have to go the same way.

Jesus Our Brother

Finally, remember that God wrote a new story for the whole world when he sent Jesus to us to become our brother.

In Genesis, Abel’s blood cries out from the ground, and God hears it. The ground has been receiving blood ever since.

And then one day…
the world spilled another innocent brother’s blood.

Jesus.

But this time the story didn’t end with the blood crying out for justice.

Because on the third day, God answered the violence of the world with life.

With resurrection.

Which means Cain doesn’t get the last word.

Violence doesn’t get the last word.

Death doesn’t get the last word.

God does.
