When God Says ‘Do Not Kill but Your Heart Screams for Blood
When God says, “Do not kill,” it sounds holy until your heart is burning with rage. It’s easy to quote “Vengeance is Mine,” says the Lord (Romans 12:19) but what happens when the victim is a child? When the crime feels unforgivable? In those moments, our humanity doesn’t whisper mercy, it demands blood. We want justice now. We want the guilty erased. And suddenly, God’s command feels less like comfort… and more like agony. Why would a holy God restrain our anger when evil feels so obvious? Here’s the uncomfortable truth, killing the guilty will never resurrect the innocent. God’s justice does not revolve around our rage and it rests on His holiness and authority. He sees every tear, every scream, every stolen innocence and yet He still says, “Leave vengeance to Me.” That command hurts because it forces us to surrender control and trust a justice we cannot yet see.
Can we trust a God who hates evil more than we do… to end it without becoming it?
I am against killing a criminal under God’s law. Scripture says, “Vengeance is Mine,” declares the Lord. But let’s be honest those words are easy to quote and brutally hard to live by. When the victims are vulnerable when the victim is a five-year-old child no verse immediately quiets the rage. We imagine the fear, the confusion, the pain that no child should ever experience and in that moment, our humanity erupts. Our hearts do not whisper justice; they demand execution.
This is where faith becomes agonizing. Not poetic. Not comforting. Agonizing. Because everything in us wants instant punishment. We want the criminal erased, silenced, removed from existence as if death could undo what was done. As if killing the guilty could resurrect the innocent. It can’t and that truth makes the command even harder to obey.
God’s refusal to let us take vengeance feels offensive in moments like this. It feels slow. It feels unfair. It feels like mercy is being handed to someone who does not deserve to breathe and that is exactly why it hurts because God’s justice does not revolve around our rage. It revolves around His holiness, His authority, and His terrifying patience.
The hardest part to accept is this, God wants even the worst sinner to repent. Not because their crime is small, but because His mercy is immense. He does not excuse evil He judges it perfectly. But He also knows something we refuse to face in our anger killing the criminal does not heal the victim, and it does not cleanse the world of sin. It only adds another death.
Following God here feels like swallowing broken glass. It means trusting a justice we cannot see, waiting for an answer that does not come fast enough, and believing that God can hold both wrath and mercy without making a mistake. It means laying down our right to retaliate and admitting that we are not God even when our anger feels righteous.
This command is painful because it asks us to surrender control. To believe that God sees every tear, every scream, every stolen innocence and that no evil escapes His judgment, even when it walks free for a time. His justice may be delayed, but it is never absent. His mercy may offend us, but it is intentional and His judgment, when it comes, will be complete.
To trust God here is not weakness.
It is obedience that hurts.
It is faith that bleeds.
It is choosing to believe that the God who hates evil more than we ever could also knows how to end it without becoming it.
“Beloved, do not avenge yourselves, but rather give place to wrath; for it is written, ‘Vengeance is Mine, I will repay,’ says the Lord.” — Romans 12:19
