Daily Devotional Series: The Road From Justice To Vengeance

Can I get a little nerdy for a moment? Bear with me if you lack the sci-fi gene.

Think back to the prequel episodes of the Star Wars trilogy. Think about the origins of the ultimate evil who came to be known as Darth Vader. For anyone above a certain age, Darth Vader was simply an ominous and cruel figure whose origin story was largely unknown—until Episodes I–III were released in the late 1990s and early 2000s.

Those movies told the story of how Darth Vader came to be, and it all began with a little boy named Anakin Skywalker. From an early point in Anakin’s life you can see a proclivity for recklessness and passion, but also a sense of right and wrong.

Unfortunately, in Anakin’s story this combination proves lethal. His passions rule him as he seeks to right the thing he most believes to be wrong in his life.

If you don’t know the story, I’ll summarize briefly. Anakin’s wife is prophesied to die during childbirth. Over time, Anakin builds a worldview centered almost entirely around his relationship with her. However cruel and broken the rest of the world may seem, their relationship remains the one place that feels right to him.

But when the brokenness of the world threatens that relationship, everything changes.

The moment Anakin believes his wife’s life is at risk, he takes matters into his own hands. What follows is a descent into darkness. He becomes convinced that any means are justified if they promise the power to prevent her death. In his quest to right what he believes is wrong, he becomes the very evil he once fought against.

Anakin is a powerful illustration of a principle often summarized by Lord Acton: “Power tends to corrupt, and absolute power corrupts absolutely.”

Power, in one sense, is the ability to act as the arbiter of right and wrong. To take that role upon oneself—even in pursuit of what seems righteous—is to step into the muddy waters of justice in a broken world. More often than not, it leads a person into the very evil they originally sought to correct.

If lessons from the Star Wars universe don’t resonate with you, Scripture offers an even clearer example.

This morning I was reading the story of Amnon and Tamar in 2 Samuel 13. If you’re unfamiliar, Amnon is the eldest son of King David, and Tamar is one of David’s daughters.

The story begins with Amnon being “in love” with Tamar. But what initially appears to be love quickly reveals itself to be something else entirely—lust. Tamar is his half-sister, and such a relationship was strictly forbidden under God’s law (Leviticus 18:9).

Amnon devises a plan to lure Tamar into a private place under the pretense of caring for him while he is ill. Tamar resists him and even appeals to God’s law, urging him not to commit such a disgrace in Israel. But Amnon refuses to listen. Overcome by lust, he rapes his own sister.

It is a horrifying story. But the aftermath is where many of the deeper lessons lie.

Absalom, another son of David and Tamar’s full brother, hears what has happened. The text tells us he says nothing to Amnon—“neither good nor bad” (2 Samuel 13:22). But internally, he burns with hatred.

Two years later, Absalom executes a carefully crafted plan. He lures Amnon into a vulnerable situation and has him killed.

Justice is served… or is it?

This story reveals several hard truths about human nature.

First, lust often disguises itself as love. Amnon claims to love Tamar, but his actions reveal the truth. Lust reduces a person to an object. Once Amnon gets what he wants, the text tells us that his hatred for Tamar becomes even greater than his supposed love (2 Samuel 13:15). He has her thrown out and the door bolted behind her.

So much for love.

Lust corrupts our ability to see clearly and judge rightly. Even when Tamar appeals to God’s law, Amnon cannot hear her. His desires have already clouded his mind and hardened his heart.

Second, sin flows downhill.

Consider David. Some of David’s greatest failures were rooted in lust—his adultery with Bathsheba and the murder of Uriah to cover it up (2 Samuel 11). We should not be surprised, then, when we see similar patterns emerging in his sons.

Scripture warns that the consequences of sin often ripple through generations (Exodus 20:5). And here we see that reality playing out. Yet there is also an escalation. David commits adultery; Amnon commits incest and rape.

This is the nature of sin. It distorts, it perverts, and it escalates. Left unchecked, sin rarely remains contained. It grows.

Which raises an uncomfortable question: who is responsible here?

Almost everyone—except Tamar—shares some measure of blame.

This leads to a third lesson: passivity toward sin often transmits guilt toward its consequences.

David’s role in this story is defined by weakness. The warning signs are obvious: Amnon’s manipulative behavior, his strange request, the vulnerability of Tamar being sent alone to care for him. Yet David does nothing to intervene. And even after learning what has happened, his anger results in no meaningful action (2 Samuel 13:21).

As much as we rightly condemn Amnon, David’s passivity creates the conditions in which this evil unfolds.

And this sets the stage for Absalom.

Absalom becomes the central figure of this reflection because of who we know he eventually becomes. Later, he will rebel against his father, steal the loyalty of the people, and attempt to take David’s throne (2 Samuel 15).

But his descent does not begin with obvious evil. In fact, his initial motivation seems understandable. His sister has been violated. Justice has not been served. Someone must do something.

So Absalom takes matters into his own hands.

This is where Scripture offers a crucial reminder: “Vengeance is mine, I will repay, says the Lord” (Romans 12:19; Deuteronomy 32:35).

Ultimate judgment—both the discernment of it and the execution of it—belongs to God.

At the same time, Scripture does not call us to passive indifference toward wrongdoing. David’s example shows the danger of that.

So what, then, is our role?

The answer begins with the imago Dei—the truth that we are made in God’s image (Genesis 1:27). As image bearers, we are meant to reflect God’s character into the world.

God is just, so we must act justly.
God is merciful, so we must love mercy.

The prophet Micah summarizes it well:

“He has told you, O man, what is good;
and what does the Lord require of you
but to do justice, and to love kindness,
and to walk humbly with your God?”
(Micah 6:8)

Notice the posture: justice, mercy, and humility.

Absalom, however, abandons humility. In killing Amnon, he places himself in the seat of ultimate authority. Death is the ultimate judgment, and by carrying it out himself, Absalom assumes a role that belongs to God alone.

This impulse—to become the final judge of good and evil—is as old as the fall itself (Genesis 3:5).

Like Anakin Skywalker, Absalom begins with a desire to correct something that is genuinely wrong. But in attempting to take ultimate authority upon himself, he becomes something else entirely.

To place ourselves in that seat is to make ourselves our own god. And when we submit to ourselves as god, we inevitably fall into the darkness already present in the human heart (Jeremiah 17:9).

This is a steep descent.

One that rarely stops where we intend.

We see the end result in Anakin: Vader.

So how should we respond to wrongdoing?

Look to Christ.

Consider the story of the woman caught in adultery (John 8:1–11). According to the law, she deserves punishment. Yet Jesus steps in—not with violence, but with wisdom and mercy.

He removes the stones from the hands of her accusers.

He refuses to allow sinful men to act as the final arbiters of justice.

And yet he does not excuse sin either.

“Neither do I condemn you,” he tells her. “Go, and from now on sin no more.”

This provides a model for us.

Intervention is good. Protecting the vulnerable is good. Confronting wrongdoing is necessary.

But we must resist the temptation to become judge, jury, and executioner.

Instead, we act justly, love mercy, and walk humbly. We protect the weak. We warn the sinner. We remember the log in our own eye (Matthew 7:3–5). And we entrust ultimate judgment to the God who judges perfectly.

In a world eager to pass verdicts, the story of Absalom reminds us that claiming ultimate authority over justice carries consequences.

So err on the side of mercy.

Judge through a log-covered lens.

And act justly in defending the weak, the oppressed, the downtrodden, and the helpless (Proverbs 31:8–9).
