Dr. James Marcum Reveals How Biblical Worship Rewires Your Brain and Reduces Stress Hormones
Cardiologist Dr. James Marcum shares groundbreaking research on how worship affects the human body at the cellular level. He explains how following biblical principles of rest, particularly Sabbath observance, can literally change your brain structure, turning off stress-related genes while activating what scientists call the "God brain." Charlie Kirk shares his personal testimony of turning off his phone from Friday night to Sunday morning, revealing how this practice dramatically reduced his stress markers and improved his health, even when it meant missing calls from the President of the United States. This panel discussion explores the intersection of faith, neuroscience, and the ancient wisdom found in Scripture.
The panel opens with a striking observation: one commandment has been largely ignored, and interestingly, God wrote the word "remember" specifically for it. This sets the stage for Dr. James L. Marcum, a cardiologist, to share his research on worship and how it affects the human body.
When Patients Face Death
Dr. Markham explains that after working as a cardiologist for many years, he has gained unique insights into human health and spirituality. When patients come to him with chest pain or having a heart attack, they come with an immediate need. But after meeting that need, he encourages them to examine their belief systems. When someone faces death, it becomes serious, and they start looking at what they truly believe.
Dr. Markham shares that his belief system centers on the Bible as truth—the owner's manual, the biblical textbook. He acknowledges this is difficult in today's world, to say that the Bible trumps science. But he maintains that the truths in the Bible are way ahead of scientific discovery.
The Sabbath and Human Physiology
As Dr. Markham discusses biblical truths with his patients, including the Sabbath, he begins explaining the physiology behind this commandment. The seventh day was a time God gave humanity to rest before the fall, when everything was perfect. At that time, people were happy, peaceful, and spent time with family. The brain structures, including dopamine pathways, were functioning perfectly.
But after the fall, things started falling apart. People began looking for other ways to find pleasure, seeking dopamine surges from various sources. In the hospital, Dr. Markham sees patients getting dopamine hits from cocaine, fentanyl, and all sorts of substances. Over time, these altered sources change the brain, and when the brain changes, our relationship with God changes, our decision-making changes—everything becomes disrupted.
The Fight or Flight Response
When people turn to artificial sources of pleasure and stress increases, the body starts producing chemicals like epinephrine, norepinephrine, and adrenaline. These stress hormones downshift the brain, impairing thinking ability and making it harder to relate to God. The entire way people deal with the world changes when this occurs.
The Bible Ahead of Science
Dr. Markham points out several examples of how the Bible was far ahead of scientific discovery. The Bible mentioned that there's weight in the wind long before Torricelli discovered it. It described the earth as round long before Copernicus. The book of Daniel contains one of the original health studies, where Daniel and his companions ate a plant-based diet. After a period of time, when compared to the control group, they were significantly better off.
Dr. Markham wonders if other doctors back then paid attention to this Babylonian study. Three hundred years later, Hippocrates said, "Let food be thy medicine and medicine be thy food." Perhaps he had heard about this study.
How Worship Activates the Brain
When asked about worship and brain activation, Dr. Markham explains that when people start getting dopamine from other sources, their neural interconnections change. He references research from Andrew Newberg, who used PET scans to examine what happens in the brain during worship. Newberg used two interventions: prayer and 12 minutes of worship, studying people who had never worshiped before.
The results were remarkable. The part of the brain called the anterior cingulate cortex started getting bigger. Scientists call this the "God brain"—where purpose, meaning, and love reside. The physiology of the brain changed, with alterations in oxytocin, dopamine, and serotonin levels. Most interestingly, the stress center of the brain, the amygdala, was turned off. All those stress chemicals—adrenaline, cortisol, and inflammatory markers—started decreasing just through worship.
Charlie Kirk's Personal Testimony
When asked how keeping the Sabbath helped him overcome stress, Charlie Kirk shares a practical and powerful testimony. He turns off his phone from Friday night to Sunday morning, extending it as long as possible because Sabbath is so peaceful. He explains this practice is essential because his phone is primarily a portal to work. With 1,500 employees and numerous responsibilities, people constantly ask him about various matters even on Saturday.
Kirk's stress levels go down significantly during this time. By Saturday afternoon, after turning off the phone Friday night, his habits begin to change. He stops reaching for the phone constantly and becomes much more present and connected to the people around him.
Biblical Rest in a Modern World
Kirk clarifies that he's not telling people they can't use electricity on the Sabbath—people can have their own opinions on that. He does use electricity for the record, but he doesn't work. He won't watch the news, read a newspaper, or have his phone on. However, he will watch college football, which some might question, but for him it's highly enjoyable and not work. He watches with his family, finding it connecting and restful.
The principle is clear: for six days you shall work, and on the seventh day you shall rest. True rest is found in Christ Jesus and with Almighty God.
No Excuses
Kirk shares, as humbly as possible, that his health markers improved dramatically. His stress went down, he lost weight, and his energy and vitality increased. Then he makes a bold statement: if he can turn off his phone and honor the Sabbath, no one has an excuse. He's missed some very big phone calls before—including calls from the President of the United States—but God told him not to work that day.
The reality is simple: you can always call people back. Kirk has found that good people, even those who aren't Christians, actually respect that he unplugs for a day. They're willing to cut him slack. And even if they aren't, he asks, "So what?" The creator of the universe commanded rest for one day. That's more important than being on the constant corporate hamster wheel, trying to get the next bonus or return the next text message.
Changing Dopamine Sources
Dr. Markham notes that Kirk is changing where he gets his dopamine from, changing his neuropathways, and God is blessing this shift. This is how humans were originally designed to function. This is one of the core principles of human design. When people break the way they were designed, bad things happen. They try to get dopamine and pleasure from other sources, downshift their brains, and trigger stress hormones like adrenaline and cortisol.
The Human Genome and Epigenetics
In 2012, the human genome project was completed and DNA was sequenced. Dr. Markham thinks of DNA as the hardware and epigenetics as the software. Over the last few years, scientists have been able to unwrap what some have called "the language of God" in medicine. They can now look at individual inputs and how they turn specific genes on and off.
Different types of worship and relaxation studies have examined kappa pathways in the brain and how they regulate genetics. Researchers have discovered that through worship—and especially Sabbath worship—they can turn off stress-related genes and change physiology. This addresses one of the root causes of the chronic disease epidemic: chronic stress.
The Future of Biblical Worship Research
Dr. Markham envisions the next step in research: taking biblical worship practices and studying individual genetics. In a few years, as science catches up with the Bible, doctors might be able to say: "For your specific genetics, 15 minutes of Bible study, 10 minutes of prayer, some laughter, and some praise produces these genetic changes." They might be able to fine-tune recommendations to help people grow their "God brain"—the anterior cingulate cortex that enlarged in studies—while further reducing the amygdala, the stress part of the brain where selfishness resides.
Fundamental to Health and Healing
The Sabbath isn't just a religious obligation—it's fundamental to health and disease reversal. As a cardiologist, Dr. Markham can place stents or perform bypass surgery, but these procedures don't heal people eternally. Biblical rest, however, not only heals eternally but also produces short-term genetic changes. These changes enable better decision-making and create healthier neural pathways.
The panel concludes with gratitude for Dr. Markham's insights, demonstrating the powerful intersection between ancient biblical wisdom and cutting-edge medical science.
