Genesis 38:7

And Er, Judah’s firstborn, was wicked in the sight of the Lord; and the Lord slew him.

That is a hard verse for people.

They read it and say, “How brutal of God to slay a man for being wicked.” But that reaction usually comes from not thinking deeply enough about what wickedness really is.

Wickedness is not harmless.

It is not private.
It is not contained.
It does not sit still.

It spreads.

A man can become so wicked that it is actually an act of mercy for the Lord to put him out of his misery. That sounds severe to modern ears, but it is true. We tend to think of mercy only in soft terms. But sometimes mercy is also decisive. Sometimes mercy stops what would otherwise keep spreading.

That is the issue with wickedness.

It is contagious.

Wicked people pull other people into their darkness. They do not destroy only themselves. They stain others. They corrupt others. They normalize what should never be normal. So when the Lord deals with wickedness in a direct and final way, He is not acting randomly. He is acting in wisdom. He is acting in justice. And yes, He is acting in mercy too.

The Bible speaks of sin unto death. That is not the idea of one isolated failure, one bad moment, one single stumble. It is speaking of a life of sin. A settled pattern. A path a person keeps choosing and keeps hardening into until there comes a point where the Lord says no more.

And when that moment comes, it is not because God has lost control.

It is because He sees perfectly.

He sees what the person is.
He sees what the person is becoming.
He sees who else will be harmed if it continues.

We do not see like that.

We tend to measure everything by the moment in front of us. God measures the whole matter completely. He knows the reach of wickedness. He knows the damage it does. He knows the misery it creates, both in the sinner and in those drawn into that sinner’s orbit.

So when Scripture says, “The Lord slew him,” it is not inviting us to accuse God. It is calling us to remember that the Lord sees sin far more clearly than we do.

And that ought to make us sober.

Because our culture laughs at wickedness.
It markets wickedness.
It celebrates wickedness.
It calls evil freedom and darkness authenticity.

But the Lord still sees wickedness as wickedness.

And He still deals with it.

That is why this verse matters. It reminds us that sin is not a toy. It is not a phase. It is not something to flirt with and assume there will never be consequences. There comes a point when the Lord, in wisdom and mercy, deals with the problem decisively.

That should make us thankful for grace.

Because apart from the mercy of God, every one of us would be swallowed by sin. The answer is not to look at Er and feel superior. The answer is to look at the seriousness of sin and thank God for a Savior who delivers us from its dominion.

Sin kills.

Christ saves.

Wickedness spreads.

Jesus sets free.

And the God who judges sin is the same God who warns us, calls us, and offers mercy before judgment ever falls.
