WHEN SIN SPREADS

Cain and Abel

One Story. One God. One Unfailing Love.

THE FIRST MURDER

There are some stories so heartbreaking that you almost wish you had never heard them. The recent story surrounding Lindsay Clancy is one of those. A mother was accused in the deaths of her three young children, leaving a family to live with an unimaginable loss. I think about Lindsay’s parents. They didn’t just lose three grandchildren. They lost their daughter too. I can’t imagine loving your daughter and grandchildren, only to have your family shattered by a tragedy so devastating there aren’t words big enough to describe it.

And that brings me to our story today. Murder didn’t begin with modern society. The very first murder happened at the beginning of human history—and it happened inside the very first family. A brother killed his brother.

Let’s go back.

Adam and Eve had left the Garden of Eden. Sin had entered the world, and its consequences were now reaching the next generation. Their first son was Cain. Then came Abel. Cain was a farmer; Abel was a shepherd. One day, both brought offerings to God.

And before we move on, notice something we can easily miss: God had not stopped loving this family.

Adam and Eve had sinned, but God had not abandoned them. After they tried to cover themselves with fig leaves, God Himself provided their covering. Genesis 3:21 says, “The LORD God made garments of skin for Adam and his wife and clothed them.” Even after their rebellion, God was still providing for the people He loved.

Then came their sons.

Cain brought some of the fruit of the soil. Abel brought the best portions from the firstborn of his flock.

Hebrews 11:4 tells us Abel brought his offering “by faith.” Genesis says the LORD looked with favor on Abel and his offering, but not on Cain and his offering.

Cain was furious.

But here is where God’s love becomes impossible to miss.

God saw Cain’s anger before Cain acted on it. He could have simply allowed Cain to follow his anger to its terrible end. Instead, God came to him.

“Why are you angry?”

Then came the warning: “Sin is crouching at your door; it desires to have you, but you must rule over it.” Genesis 4:6–7.

Think about that.

God loved Cain enough to warn him.

He saw what Cain could not—or would not—see. He knew where that anger was leading, and He gave Cain an opportunity to turn around.

That is love.

But Cain didn’t listen.

One day, Cain and Abel were in the field. Cain rose up against his brother and killed him.

The first murder.

And it happened inside the first family.

Can you imagine Adam and Eve receiving that news? They had already lost the Garden. Now they had lost a son.

One son was dead. The other had killed him.

And perhaps the deepest heartbreak was watching Cain turn his heart farther and farther from the God who still loved him.

Sin had entered their home, but God’s love had not left it.

Then God came looking for Cain.

“Where is your brother Abel?”

“I don’t know,” Cain answered. “Am I my brother’s keeper?”

But God knew.

“Your brother’s blood cries out to me from the ground.”

God heard Abel.

Abel’s life mattered to God. His death mattered to God.

God did not overlook what had happened. He did not call evil good. He did not erase Cain’s consequences.

But even in judgment, Cain was not abandoned.

That is something we can easily miss.

God’s unconditional love does not mean He ignores our sin. It means our sin does not make Him stop loving us.

It’s important to remember that this was before God had established human government with the authority to carry out the death penalty. That instruction came later, after the flood, in Genesis 9:6: “Whoever sheds human blood, by humans shall their blood be shed; for in the image of God has God made mankind.”

Cain’s story is not God declaring murder acceptable. It is another step in God’s unfolding revelation of justice and human responsibility.

But look at what Cain’s story teaches us about the heart.

Sin rarely begins with the final act. It begins much earlier—in the heart.

Anger.

Jealousy.

Resentment.

Unforgiveness.

And God sees it before anyone else does.

“Sin is crouching at your door.”

Maybe there is something you’ve been carrying that God has been asking you to surrender. Not because He wants to condemn you, but because He loves you too much to let sin destroy you.

That warning to Cain was an act of love.

And it may be an act of love when God warns us, too.

But Cain didn’t listen.

And look how quickly the story changes.

God created a perfect world. Adam and Eve sinned. Their son murdered his brother. Violence spread. Wickedness increased. Humanity moved farther and farther from God.

Until Genesis 6:6 tells us, “The LORD regretted that he had made human beings on the earth, and his heart was deeply troubled.”

We often focus on God’s judgment.

But look again.

His heart was grieved.

Why?

Because sin was destroying the very people He had created and loved.

The God who loved Adam and Eve enough to cover them.

The God who loved Cain enough to warn him.

The God who heard Abel’s blood crying from the ground.

That same God was now watching His creation destroy itself.

His heart was broken.

Love grieves when the ones we love are hurting themselves and one another.

And yet—even here—God’s love was still at work.

Genesis gives us one small sentence of hope:

“But Noah found favor in the eyes of the LORD.” Genesis 6:8.

The world was becoming darker.

But God had not stopped loving His creation.

Not Adam.

Not Eve.

Not Cain.

Not Abel.

Not Noah.

And not us.

That is the thread running through the story.

Sin spreads.

But love remains.

Tomorrow, we’ll discover what happened next—and perhaps we’ll see God’s Thread of Love running through the tapestry of another familiar story.
