Psalm 37:1-9 teaches that worrying about evildoers is pointless because they’re temporary (like grass that withers), God sees everything, trusting Him brings better outcomes than fretting does, and He will establish justice in His timing—not ours.

---

 

Evil people seem to prosper while good people struggle. Corrupt leaders stay in power. Dishonest coworkers get promoted. Bad behavior gets rewarded while integrity gets overlooked.

If you’ve ever felt that frustration, you’re not alone. David felt it too, and Psalm 37 was his response. These nine verses tackle one of the most difficult tensions in faith: Why does God let wicked people succeed?

David doesn’t give us philosophical theories. He gives us four practical reasons to stop fretting and start trusting. Each reason addresses a different aspect of how God works, and together they form a complete answer to the worry that eats away at us when we see injustice winning.

The word “fret” appears three times in these verses. David wasn’t telling us to pretend evil doesn’t exist. He was showing us why anxiety about it accomplishes nothing—and what to do instead.

 

Verse 1: Do Not Fret Because of Evildoers

“Do not fret because of those who are evil or be envious of those who do wrong.”

The Hebrew word translated “fret” is charah, which means to burn with anger or to be inflamed. David is addressing that hot, frustrated feeling that rises up when we see people getting away with things they shouldn’t.

Notice he doesn’t just say stop being angry. He says stop being envious. That’s the deeper issue. We’re not just mad that evil exists—we’re bothered that it seems to work better than righteousness does.

Someone lies their way into a job you deserved. Someone cheats and still wins. Someone manipulates and gets ahead. Your first response might be anger, but underneath is often envy. They got something you wanted, and they didn’t even have to be good to get it.

David’s command is blunt: Stop it. Don’t fret. Don’t envy. But he doesn’t leave us there. He immediately tells us why.

 

Verse 2: They’re Temporary

“For like the grass they will soon wither, like green plants they will soon die away.”

This is reason number one: Evil people and their success are temporary. David uses two images—grass and green plants—to make the same point. They look alive and healthy right now, but that won’t last.

Grass in Israel wasn’t like grass in other climates. It would spring up after rain, look green and vibrant for a short time, then wither under the heat. It was the perfect picture of something that appears strong but has no staying power.

Your frustration with evil assumes it’s permanent. David is telling you it’s not. The person who lied their way to the top? Their foundation is rotten. The system built on corruption? It will collapse under its own weight. The injustice that seems unshakable? God sees it, and it has an expiration date.

This doesn’t mean evil disappears tomorrow. It means you’re watching a dying thing, even if it doesn’t look dead yet. Fretting over something that’s already on its way out makes no sense.

 

Verses 3-4: Trust God and Find Real Satisfaction

“Trust in the Lord and do good; dwell in the land and enjoy safe pasture. Take delight in the Lord, and he will give you the desires of your heart.”

Here’s reason number two: Trusting God produces better outcomes than fretting ever could.

David gives us a progression. Trust in the Lord. Do good. Dwell in the land. Enjoy safe pasture. Each step builds on the previous one. Trust leads to action. Action leads to stability. Stability leads to satisfaction.

Then comes verse 4, which people often misunderstand. “Take delight in the Lord, and he will give you the desires of your heart” doesn’t mean God becomes a vending machine where you put in delight and get out whatever you want.

The Hebrew word for “delight” is anag, which means to be soft or pliable. When you delight in the Lord, you’re allowing Him to shape you. And when He shapes you, your desires change. The things you wanted when you were anxious about evil stop mattering as much. New desires form—ones that align with who God is and what He’s doing.

So God does give you the desires of your heart, but not because He’s granting wishes. He gives them to you by changing what your heart desires in the first place. That’s a far better outcome than getting what you wanted while staying anxious.

 

Verse 5: Commit Your Way to the Lord

“Commit your way to the Lord; trust in him and he will do this.”

Reason number three: God takes responsibility for what you commit to Him.

The word “commit” in Hebrew is galal, which literally means to roll. Picture yourself carrying a heavy burden, struggling under its weight, and then rolling it off your shoulders onto someone stronger. That’s what David is describing.

When you commit your way to the Lord, you’re not just asking for help. You’re transferring ownership. You’re saying, “This is yours now. I’m done trying to manage it.” And when you do that, God acts. “He will do this” is a promise. What will He do? The next verse explains.

 

Verse 6: He Will Establish Justice

“He will make your righteous reward shine like the dawn, your vindication like the noonday sun.”

God will make your righteousness evident. The word “vindication” here means justice or judgment. God promises that the truth about you—about your character, your choices, your integrity—will become as obvious as sunlight.

This is why fretting is pointless. You’re worried that evil is winning and good is losing, but that’s only true if you’re keeping score too early. God hasn’t closed the books yet. The final accounting hasn’t happened. When it does, righteousness will be unmistakable, like the sun at noon when there are no shadows left to hide in.

You might not see it today. You might not see it next month. But God sees everything, and He will make sure what’s true becomes clear to everyone else eventually. That’s His job, not yours. Your job is to keep doing what’s right and let Him handle the timing.

 

Verse 7: Be Still and Wait

“Be still before the Lord and wait patiently for him; do not fret when people succeed in their ways, when they carry out their wicked schemes.”

“Be still” translates the Hebrew word damam, which means to be silent or to stop striving. It’s not passive resignation. It’s active trust. You stop trying to force outcomes. You stop obsessing over what evil people are doing. You stop checking their social media to see if karma has caught up with them yet.

Waiting patiently is harder than it sounds. David repeats the command not to fret specifically when evildoers succeed. He knows that’s when your anxiety spikes. When the corrupt politician wins reelection. When the dishonest person gets the promotion. When the manipulator gets away with it again.

David is saying: Even then, be still. Even then, wait. God’s timing is not your timing, but it’s always right.

 

Verses 8-9: Anger Leads to Evil

“Refrain from anger and turn from wrath; do not fret—it leads only to evil. For those who are evil will be destroyed, but those who hope in the Lord will inherit the land.”

Here’s reason number four, and it’s the most sobering: Fretting doesn’t just fail to solve the problem—it makes you part of the problem.

David says fretting “leads only to evil.” The Hebrew construction here is emphatic. Fretting doesn’t lead to a little bit of evil or sometimes evil. It leads only to evil. Nothing good comes from it.

When you obsess over evildoers, you start to think like them. You consider shortcuts you normally wouldn’t. You justify behavior you’d normally condemn. You become bitter, cynical, angry. Before long, you’re operating from the same place they are—just with different targets.

Anger can feel righteous, especially when it’s directed at evil. But David warns us to refrain from it. Not because evil doesn’t deserve anger, but because anger in your heart rarely stays focused where it should. It spreads. It distorts your judgment. It turns you into something you don’t want to be.

Meanwhile, those who hope in the Lord—who trust His timing and His justice—will inherit the land. They’ll receive what God promises. They’ll experience the satisfaction that comes from righteousness. Not because they fought harder or worried more, but because they trusted better.

 

What David Learned

David wrote Psalm 37 as an old man looking back on a long life. He’d seen plenty of evil. He’d been betrayed, hunted, slandered. He’d watched wicked people prosper while righteous people suffered. But he’d also watched long enough to see how things ended.

Evil doesn’t last. It withers. It collapses. It gets exposed. Always.

And righteousness, even when it’s ignored or attacked, endures. God sees it. God vindicates it. God rewards it. Always.

Those aren’t slogans. They’re observations from someone who lived long enough to watch the pattern repeat itself over and over. David isn’t asking you to trust a theory. He’s asking you to trust what he saw with his own eyes across decades of life.

 

Why This Matters Today

We live in an age of instant information. You can watch evil succeed in real time, around the clock, on every device you own. That makes fretting easier than ever. It also makes David’s wisdom more necessary than ever.

God has not changed. Evil is still temporary. Righteousness still endures. Justice is still coming. Your job is still the same: Trust God, do good, be still, and wait.

Fretting won’t speed up God’s timeline. It will only corrupt yours. So stop checking the scoreboard. Stop comparing your obedience to their success. Stop letting their wickedness define your peace.

Do what’s right. Trust God with the results. And watch what He does with both.
