When praying doesn't work: understanding dark and wrong intrusive thoughts

Struggling with intrusive thoughts that feel dark, wrong or spiritually frightening? Why do I have such bad, taboo, and sinful thoughts when I’m supposed to be a follower of Jesus? Explore faith, OCD and how CBT can help you respond differently.

If you are a Christian struggling with terrifying, graphic, or abhorrent thoughts, you might feel like you are the only one. You might worry that these thoughts are proof of a hidden demonic attack, a lack of genuine salvation, or a reflection of your heart.

But there is a liberating truth you need to know: the content of your intrusive thoughts is completely irrelevant. What you are experiencing isn't a moral failure—it might well be the exhausting, mechanical loop of Obsessive-Compulsive Disorder (OCD).

The Day the Certainty Shattered

The first time I experienced an intrusive thought, I was 15 years old, sitting by a pool on a family holiday. Out of nowhere, an incredibly alarming, dark thought flashed into my mind—a thought that completely contradicted everything I believed about my faith, my character, and my morality.

Immediately, my stomach flipped, my heart raced, and I felt sick.

For the next few weeks and months, that internal voice seemed to get louder and louder. It was constant. Every time a terrifying or blasphemous thought spoke up, I felt sick with anxiety. I began to wonder whether it was telling me a hidden truth about myself that I didn’t know. Or worse, that my mind would take over and I wouldn’t have control over what I might do.

The thoughts quickly spiralled, and suddenly, normal daily interactions became distressing and threatening. Walking down the street or hanging out with friends was met with screaming internal echoes of "What if?" and an intense, exhausting state of hypervigilance.

With each distressing thought came a wave of panic, which I started to question too: "Is this anxious feeling in my body a confirmation that the thought is true?" Everything—every thought, interaction, and physical sensation—was cast in doubt. This was met with an urgent, desperate need to get to a place of certainty. I was continually scouring my own brain for evidence to confirm or deny the intrusions. I was mentally checking all of the time.

The Vicious Cycle

Spiritually, I was a mess. I spent hours trying to "take authority over the enemy" by shouting at Satan to "get away from me," only for the unwanted thoughts to return moments later. Well-meaning pastors and friends saw this exclusively as a spiritual battle to be prayed away; not clinically treated. I often found myself pleading with God to take these thoughts away altogether. None of it worked.

I didn’t know it then, as I hadn’t really heard of OCD except for people who like things to be clean and orderly (a massive misconception by the way), but I was trapped in a classic manifestation of Obsessive Compulsive Disorder or OCD.

In its simplest form, OCD occurs when someone experiences intense, unwanted thoughts, urges, or images (obsessions) that trigger a sudden wave of panic, guilt, or doubt. To make that agonising discomfort go away, the person performs repetitive actions, mental arguments, or reassurance checks (compulsions). While these habits bring temporary relief, they actually feed the anxiety and keep the vicious cycle spinning.

When you add a deeply held Christian faith into the equation, the distress becomes debilitating. Sufferers are often trying to faithfully obey scriptures like "take every thought captive to obey Christ" (2 Corinthians 10:5).

Often sufferers begin to wonder that because the thought occurred in their mind, they must secretly desire it.

So when a disturbing, graphic or abhorrent thought or image pops up, it is immediately met with immense moral shame.

The clinical truth:

Here’s the secret that OCD doesn't want you to know: Intrusive thoughts happen to everyone.

If you ask anyone whether they have ever had a bizarre, aggressive, or completely inappropriate flash through their mind—like pushing over someone in a queue, or shouting something wild in a quiet meeting—most honest people will say yes.

A friend of mine once confessed that while holding her friend’s newborn, she had a sudden, terrifying thought about drop-kicking that bundle of joy across the room!

We all have intrusive thoughts. The difference is that a person without OCD dismisses them as neurological junk mail. But for those of us who get stuck in a cycle of distress, it is because we attach a heavy moral meaning to the thought. We treat a random spark as a reflection of our soul.

OCD’s Favourite Weapon: Taboo Themes

Intrusions can take on different themes and can also hop about; just when you think you’ve broken the beast, it rears its head with another idea. Intrusions can vary from worrying about leaving the house unlocked to distress that one is a dangerous person like a paedophile. People worry about whether they’ve run someone over on the way home from the gym or whether they will shout at their boss at the office Christmas party. Christians may even have inappropriate thoughts about Jesus popping into their mind and then carry a deep shame as He has already seen that thought. Fears of somehow being contaminated, fears of having doubts within a relationship… the list goes on.

OCD loves to morph into highly taboo, graphic, and abhorrent themes to shock you into a state of panic. But whether you are worrying about leaving the house unlocked, or worrying that you are secretly a monster, all intrusive thoughts share the exact same foundation: They bring immense distress, and they demand absolute certainty.

And as a therapist who works with many people with OCD, the actual content and nature of the intrusive thoughts are essentially irrelevant – what I’m most interested in, is the meaning someone gives to having had the thought. For instance, having a graphic image come to mind, might mean that someone thinks they’re a bad or dangerous person. This is the crux of the problem and if we can establish that, then we can do something about it.

What does God say about your intrusive thoughts?

The Lord is gracious and compassionate, slow to anger and rich in love (Psalm 145:8). And perfect love casts out all fear (1 John 4:18). I believe the Lord loves to see His children walk into the full freedom and peace that He has already paid for on the cross. That includes freedom from the anxiety of intrusive thoughts. He already knows which thoughts have crossed our minds (Psalm 139:1-2) and He’s not scared or wobbled by them. And He’s given us tools to conquer them!

Faith and Therapy

Through Cognitive Behavioural Therapy (CBT), we cooperate with God’s design for healing and freedom from OCD by helping people understand the pattern underneath the distress: intrusive thoughts, anxiety, compulsions and the urgent search for certainty. ERP (Exposure and Response Prevention) is an important and well-evidenced part of CBT for OCD, but CBT is not only about exposure. It can also involve learning to identify how OCD misinterprets thoughts as threats, reducing reassurance-seeking and rumination, building tolerance of uncertainty, and responding to intrusive thoughts with more distance and compassion rather than fear, shame or frantic analysis.

Over the years, I’ve learned that my intrusions are usually a sign that I’m feeling unsettled about something – often completely unrelated to the intrusion. Big life events such as starting a family or a new job, or even seasonal (but potentially stressful) celebrations like Christmas or birthdays, are when I’m most likely to hear my intrusions louder than on the average day. And now I’m able to just notice it for what it is – a thought. An unpleasant thought but a thought, nonetheless. It has the same weight to it as wondering what I’ll eat for dinner or remembering to text a friend back. All. Just. Thoughts.

If you’re feeling burdened and overwhelmed by the intrusive thoughts that you’re experiencing; or maybe you carry a deep sense of shame about them – please take heart that there is real help and healing available for you. I really enjoy seeing people find real freedom from their intrusions; using compassion and CBT (Cognitive Behavioural Therapy), we can work together to quieten the screaming voice of OCD and come to a place of real peace.
