Brain and the Bible. Part 5: Renewing the Mind – Breaking Repetitive Thought Patterns

Psychologist Anna Ponnudurai explains how repetitive thoughts shape the brain and how Scripture and practical strategies can help break unhealthy patterns.

Key points:

Registered psychologist Anna Ponnudurai says repetitive thoughts are a normal part of how the brain works, but not all thoughts are helpful.

“We all have repetitive thoughts, but the key is asking whether they are helpful or harmful, whether they are faith based or fear based.”

She explains that every thought contributes to how the brain is wired over time.

“Each thought strengthens pathways in our brain, so we need to be mindful of what we are reinforcing.”

Anna points to Philippians 4:8, which encourages people to focus on what is true, noble, right and pure.

“There is a real neuroscience backed strategy in that. It helps guide healthy thinking and neural wiring.”

She also highlights the biblical idea of capturing thoughts, which closely aligns with principles used in Cognitive Behavioural Therapy.

“It’s about being able to notice your thoughts, get to the root of why you’re thinking that way, and then decide what to do with it.”

Anna describes this as “circuit breaking” negative thinking patterns.

“Start by noticing the thought. Write it down, go for a walk, or challenge whether that thought is actually true and whether you want to accept it.”

She adds that simple physical actions can also help interrupt repetitive thinking.

“Even things like putting ice on your pulse points or having something sour or spicy can stop your brain for a moment, just long enough to choose how to respond.”

These small interruptions can create space to shift from automatic reactions to intentional thinking.

The connection between Scripture and psychology is striking.

“Early processes of what we now call cognitive behavioural therapy are already present in the Bible,” she said.

For those struggling with repetitive or anxious thoughts, Anna encourages a practical and hopeful approach.

By becoming aware of our thinking patterns and intentionally redirecting them, it is possible to reshape the way we think over time.
