Day 4 — Thoughts That Won’t Leave
“Search me, O God, and know my heart; test me and know my concerns. See if there is any offensive way in me; lead me in the way everlasting.”
— Psalm 139:23–24 (BSB)
You said something awkward at lunch, three days ago. Nobody else remembers. But your brain keeps playing it back, again and again, adding new ways it might have sounded. Or you lie in bed going round the same loop: What did she mean by that message? Why didn’t he reply? What if I fail? What if they’re all talking about me?
And sometimes it’s worse than replaying. A thought just flashes into your head, something shocking or ugly or frightening, a thought you would never want to act on. And then comes the panic: Why did I think that? What kind of person thinks that? Am I a terrible person?
Let’s take those one at a time.
Overthinking is when your mind keeps chewing on something without ever swallowing it. It feels like you’re solving a problem, but you’re not. You’re just going round in circles, and every lap makes the worry deeper.
Unwanted thoughts are thoughts that arrive uninvited. Almost everyone has them sometimes. Here is something important: a thought that horrifies you is not the same as a desire. The very fact that it upsets you shows what your heart actually wants. You are not your worst passing thought.
Now look at David’s prayer in Psalm 139. He’s spent the whole psalm marvelling that God knows everything about him: his sitting down and standing up, his words before he speaks them, his days before one of them came to be. And at the end, instead of hiding from that, he invites it: “Search me, O God, and know my heart.”
That’s the opposite of overthinking. Overthinking is searching yourself, endlessly, with no one to give the answer. David hands the search to God. You look, Lord. You know what’s really there. If there’s something wrong, show me, and lead me. If there isn’t, I can stop digging.
The Bible also shows people talking back to their own thoughts. In Psalm 42 the writer turns on his own mood and says, “Why are you downcast, O my soul? Why the unease within me? Put your hope in God.” He doesn’t just listen to his feelings. He talks to them. Paul calls this taking “captive every thought to make it obedient to Christ.” You can’t always stop a thought from arriving. But you don’t have to invite it to stay for dinner.
And when the thought is an accusing one, you’re disgusting, you’re hopeless, God must be sick of you, answer it with the truth: “there is now no condemnation for those who are in Christ Jesus.” Not less condemnation. No condemnation.
Some people find that unwanted thoughts become relentless: they come many times a day, and they feel driven to check, repeat or confess things over and over just to make the feeling stop. If that’s you, please tell a parent or trusted adult and see a doctor. It is common, doctors understand it well, and it can be treated. And if your thoughts ever turn toward hurting yourself or not wanting to be alive, tell a parent or trusted adult right away.
Your mind may be noisy. But God knows every thought, and He’s not afraid of any of them.
Think about it: Which thought or worry keeps coming back to you? What true thing could you say back to it?
Try this: Next time you notice your mind looping, stop and pray Psalm 139:23–24 slowly, word for word. Then do something with your hands for five minutes: walk, wash up, kick a ball. Let God hold the question.
Go deeper: The Key Teachings of Martyn Lloyd-Jones — the Welsh doctor-turned-preacher taught that much of our unhappiness comes from listening to ourselves instead of talking to ourselves, and showed from Psalm 42 how to take our moods in hand and point them to God. Start with chapter 14, “Talking to Yourself”.
Search me, O God, and know my heart. You know every thought that runs through my mind, even the ones I’m ashamed of. When my thoughts go round in circles, help me hand them to You. When they accuse me, remind me that there is no condemnation for those in Christ. Lead me in the way everlasting. In Jesus’ name, Amen.
