When thoughts run like wild horses
My thoughts often feel like a herd of wild horses, eager to run. At times, they carry me to open fields filled with gratitude, joy, and imagination. These places are beautiful, colourful, and full of possibilities. They refresh my soul, fill me with new energy, and create hope that nourishes both my body and spirit. In these moments, my thoughts become companions that encourage, inspire, and establish life-giving rhythms within me.

Unfortunately, not every journey is so calm and uplifting. When uncertainty or worry grips me, these wild horses charge into dark valleys and dense bushes. They roam wherever they please, and I lose control. The experience becomes frightening, filled with fear and anxiety. My body prepares for danger: my temperature rises, and my breathing becomes shallow. Most often, these perilous rides occur at night, when I can hear my heartbeat echoing through the silence.
Recently, while reading “Switch On Your Brain” by neurologist Dr Caroline Leaf, I was reminded of just how powerful our thoughts are. They shape not only my mind but also my body and the quiet spaces of my soul.
Mind and Brain — What is the difference?
The Bible teaches that God created us with free will: the ability to think, choose, and see life from different perspectives. Our brain is the physical hardware of the body, while the mind is like the software that directs it.
Psychology, medicine, and faith traditions may differ in many ways, but they agree on this: our thoughts are never neutral. They shape our emotions, influence our choices, affect our health, and connect us to meaning and identity.

The lasting impact of our Thoughts
Neuroplasticity
Our thoughts are not just fleeting clouds. They build physical structures in the brain made of proteins. Thinking, feeling, and deciding all cause changes in the brain. The brain’s ability to constantly rewire itself is known as neuroplasticity.
The remarkable truth is that our brains can change throughout our entire lives. However, this can work for or against us. What we focus on most will strengthen, whether it is positive or negative. Therefore, the focus of our thoughts has an impact.

Our DNA
Research shows that our thoughts can even influence the shape and function of our DNA. Negative, fearful thought patterns can place stress on the body, while grateful and hopeful thoughts strengthen resilience. What we dwell on does not just shape our feelings in the moment; it also influences our long-term outlook. Our thoughts generate actual signals that impact our cells, which in turn affect our health, energy, and even the expression of our genes.
Science has shown how thought networks are transmitted through DNA in sperm and ova to the next four generations.
Epigenetics
Epigenetics describes how our thoughts and choices impact our physical brain, body, mental health, and spiritual growth. Studies in epigenetics indicate that we inherit various traits, both positive and negative, from our ancestors across generations. But because of our free will, our mind can determine whether these genes are “turned on” or “turned off.”

We do not have to repeat the negative patterns of our ancestors. Instead, we can make conscious life choices to overcome these tendencies by altering our patterns of expression. While the mistakes of our parents may create certain predispositions, they do not dictate our fate. It is our responsibility to recognise these tendencies, evaluate them, and decide to eliminate them.
Why our perceptions matter
Our interpretation and response to the environment shape our biology. Survivors of deep trauma, like Holocaust survivors, demonstrate this truth: while we cannot always choose our circumstances, we can choose how we frame them. As the poet of Invictus reminds us, “I am the master of my fate, I am the captain of my soul.”

Learning to focus and guide our Thoughts
When we consciously focus and guide our thoughts, it affects the brain in various ways—from sensory processing and neural rewiring to neurotransmitter activity, genetic expression, and even cellular functions. The effects can be positive or negative, depending on the direction we choose for our thoughts.
Research indicates that purposeful, introspective thinking enhances the brain’s non-conscious processes, increasing their effectiveness. Periods of rest enable us to disengage from the distractions of the external world and focus inward. In this contemplative state, we gain perspective, wisdom, and a renewed opportunity for connection with God. It highlights the importance of rest and recovery. It also explains the purpose of Sunday as a designated day of rest.
When we fail to engage in disciplined self-reflection, the consequences can be detrimental. This neglect can result in low self-esteem, depression, anxiety, and even physical health problems. We may find ourselves trapped in our challenges, struggling with short-term memory, and losing the ability to identify clear solutions.
A closing Thought
We have the freedom to choose how we direct our attention, and this decision significantly influences the way our brains change and function, including the chemicals, proteins, and connections within. Scientists have demonstrated that the relationship between our thoughts and our self-perception—shaped by our beliefs, dreams, hopes, and ideas—has a profound effect on brain activity.

The book reminded me of the significant impact that my thoughts have on various aspects of my life. Disappointments, uncertainty, and pain are all part of the human experience. I don’t need to deny or dismiss my thoughts; instead, I can redirect them to truth with gratitude and hope. This discipline requires consistent willpower, patience, and practice. However, it is critically important because our thoughts dictate the direction of our lives.
Kind regards,
