The River Within: The Brain, Cerebrospinal Fluid, and the Creator
A faith-centered reflection on Ezekiel 47, the nervous system, and the wonder of God's design.
There are moments when Scripture opens our eyes not only to God’s creation around us, but also to the wonder of His design within us.
In Ezekiel 47, the prophet describes water flowing from the temple. The river becomes progressively deeper, trees grow along both banks, and life flourishes wherever the water travels:
“Where the river flows everything will live.”
When I read this passage, I am reminded of the human brain and the life-supporting movement of cerebrospinal fluid. This is a personal spiritual reflection—not a claim that Ezekiel was describing human anatomy—but the imagery inspires me to appreciate the remarkable way God created the body.
A RIVER THROUGH THE NERVOUS SYSTEM
Cerebrospinal fluid, commonly called CSF, is a clear fluid that surrounds and supports the brain and spinal cord. It travels through interconnected spaces within the brain called ventricles and circulates around the central nervous system.
The brain has four ventricles: two lateral ventricles, the third ventricle, and the fourth ventricle. Reading about the four measurements of one thousand cubits in Ezekiel brings these four spaces to mind for me—not as an anatomical interpretation of Scripture, but as a meaningful point of contemplation.
Approximately 150 milliliters of CSF are present in the average adult at one time. The body produces roughly 400–600 milliliters each day, allowing the fluid to be renewed several times within 24 hours. CSF helps cushion the brain, transport nutrients and signaling molecules, maintain a stable environment, and assist with waste clearance.
Along the river in Ezekiel stood “a great number of trees on each side.” In my reflection, those trees bring to mind the branching beauty of neurons—the specialized cells that communicate throughout the brain and nervous system.
This comparison is poetic rather than scientific. Yet science does not lessen my wonder. Learning how the body functions deepens my gratitude for its Creator.
THE TREE OF LIFE
I sometimes think of the brain, spinal cord, and their flowing cerebrospinal fluid together as a “tree of life.” The spinal cord resembles a central trunk, nerves extend throughout the body like branches, and the brain contains an extraordinary network of communicating cells.
This is not a medical name or doctrine. It is simply an image that helps me contemplate the unity, complexity, and life-sustaining organization of the nervous system.
The river in Ezekiel brings renewal wherever it flows. Similarly, CSF continuously supports the delicate environment in which the brain and spinal cord function. The comparison invites us to pause and recognize that processes we rarely notice are taking place within us every moment.
GOD IS NOT RESERVED FOR SUNDAY
For me, faith is not limited to Sundays, holidays, or isolated moments of worship. God is present in daily life—in our questions, endurance, learning, service, and care for one another.
Glorifying God means living passionately and purposefully. The Latin root associated with “passion” carries the idea of suffering and endurance. That meaning speaks deeply to me. There have been long days and nights of studying, questioning, and persevering, but the exchange has been a growing sense of purpose.
Years ago, I began studying my Bibles carefully, passage by passage, asking God to open my eyes to truth. Over time, that practice changed how I understand both Scripture and the created world. It taught me to approach the body with humility, curiosity, and reverence.
CARING FOR WHAT WE HAVE BEEN GIVEN
We should be cautious about turning a spiritual metaphor into a medical conclusion. CSF is not scientifically established as the human soul, consciousness, or a physical channel connecting us to God. Faith speaks to questions that anatomy alone cannot answer.
But learning about CSF can still awaken wonder.
Our brains and nervous systems benefit from the ordinary foundations of health: adequate sleep, nourishing food, hydration, movement, meaningful relationships, stress support, and appropriate medical care. Caring for the body is not a way to earn God’s presence. It is one way we can honor the life entrusted to us.
Ezekiel’s river offers a picture of restoration, abundance, and life. The flowing systems of the human body offer another reason to marvel at creation.
For me, the two meet in gratitude.
God is not present only on Sunday. He is present in our endurance, our curiosity, our healing, our service, and our decision to live with intention every day.
