“The prayer of a righteous person has great power as it is working” (ESV, James 5:16). This simple verse is quoted constantly in the religious world. It does not take a scholar to recognize the importance of prayer in the life of a believer. Prayer is a commandment. It is because of our love and respect for God that we should seek to obey this command. However, if we pray purely out of obedience, we have missed the entire God designed purpose of prayer. God has given us a direct line to the throne of Heaven. The Father, Creator, and Majesty on high invites us to let our requests be made known to him (ESV, Philippians 4:6). He wants to give his people what they ask for! How wonderful a blessing is this? He is the Father watching over his people, ready to provide for their needs. It’s a commandment, it’s a way of making requests, intercessions, thanksgivings, and so much more. While the above points reveal some purposes of prayer, there is often a fascinating and wonderful design of prayer that is left unspoken. Prayer can also be the vehicle through which we change our actions resulting in the transformation of our minds. Prayer should transform you from the inside out. Modern research has concluded that prayer has a profound impact on the physical brain. The way we think determines who we are and who we will become. When God commanded us to pray, he did so with a purpose. He designed our brains to be molded and changed in extraordinary ways. The evidence presented will be a means of understanding what happens inside the brain as you pray. First, I will lay out what the scriptures say about prayer, then present the discoveries found in this field, and finally how to apply what has been learned. I in no way claim to be a professional or even knowledgeable in the scientific side of this research. However, I have compiled this information from many peer reviewed, respected, and professional sources on the subject of neuroscience.
Theological Background
Prayer is an essential aspect of the Christian walk. In the scriptures, we are constantly reminded to pray. It can be seen as an act of worship, as well as an avenue in which a person can cultivate a personal relationship with God. As one prays, their faith and walk with Christ is strengthened and deepened. James writes a powerful message on how and why prayer is necessary.
Is anyone among you suffering? Let him pray. Is anyone cheerful? Let him sing praise. Is anyone among you sick? Let him call for the elders of the church, and let them pray over him, anointing him with oil in the name of the Lord. And the prayer of faith will save the one who is sick, and the Lord will raise him up. And if he has committed sins, he will be forgiven. Therefore, confess your sins to one another and pray for one another, that you may be healed. The prayer of a righteous person has great power as it is working. Elijah was a man with a nature like ours, and he prayed fervently that it might not rain, and for three years and six months it did not rain on the earth. Then he prayed again, and heaven gave rain, and the earth bore its fruit. (James 5:13–18, ESV)
This passage stresses the idea of praying in every situation. There are many wonders of prayer stated in this passage. We are commanded to pray in suffering, using prayer as a tool to deal with hard times and times of mental struggle. The explanation for this will be presented a little later in the research provided. James also says if someone is sick, pray to God to let him take control of all the earthly struggles. God is providentially providing and caring for his people. He works through his nature in marvelous ways. Pray for the spiritual condition of each other. When sin takes over, give it to God. God can handle nature at the request of prayer if it lines with his will. There are so many functions and benefits of prayer presented in the scriptures.
Prayer is mentioned throughout the Bible. It is first mentioned all the way back in Genesis 4 when “people began to call upon the name of the Lord” (ESV). There are other passages in scripture that display the power of prayer. One of my favorite passages in scripture states, “Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect” (Romans 12:2-3, ESV). Later in verse 12 he elaborates on how to achieve this transformation and states to “be constant in prayer” (ESV). As Christians we must pray to take on a constant renewal of our minds so we can be molded into something far greater. To change and renew the mind, prayer is essential. The research in this study reveals the intention of this powerful statement of transforming the mind.
What happens when an individual prays? Modern science has made groundbreaking discoveries that further prove the beautiful design of spirit and nature that God created to work in harmony. Craig Groschel made a statement that has stayed in my mind ever since reading it. In his book Winning the War in Your Mind he says, “If you want to change your life, you have to change your thinking” (Groeschel, 94). This is a simple, yet powerful statement. One of the greatest ways to achieve this state of change is prayer.
God’s Design for the Brain
The most fundamental aspect of changing your brain is understanding the concept of neuroplasticity. Neuroplasticity plays a major role in the process of changing the brain. It’s remarkable to discover how the brain is made to shape into the mold it is given. Neuroplasticity is defined as: “your brain’s ability to learn and adapt. Think of it as an internal rewiring process that allows your mind to grow and meet new and increased demands” (What Is Neuroplasticity?). Think of a brain like a muscle. Every time someone goes to the gym, they strengthen muscles they focus on. Eventually, they can use those muscles to a greater degree, without trying as hard as before. The same thing happens in the brain. With neuroplasticity, it’s possible to rewire the default tendencies of the brain. So, when one memorizes something, they create a strong pathway in the brain that makes it easy to pull that information to the forefront of the mind. However, this process isn’t permanent. The human brain is constantly building and removing pathways based on what information is being absorbed. When someone memorizes something but doesn’t think about or recite it often, that pathway will fade and make room for new ones. This is why it is so important for the Christian to guard his mind, think on good things, and to spend time in meditation and prayer.
So, what actually happens in your brain when you spend time in prayer? Well, there is a lot more to examine than most might think. There are many scans that are used to observe the brain. In these scans, neuroscientists can see what areas of the brain are active during specific stimulation. Scans such as MRI, SMR, fMRI, SPECT, PET, and SMR are all methods of observing these activities in the brain (Kober et al.; Newberg). Most of the evidence found in this article comes from observations made by using these methods to inspect brain activity.
Anyone can unlock control of their brain by simply praying consistently! In an article by Silvia Kober et al., a discovery was made that prayer utilizes the brain in a special way. They state: “Analysis of brain volumetry revealed that plastic changes in the brain, due to spiritual practice, favor control over one’s own brain activity.” This is an incredible observation. Cognitive ability is increased as prayer takes place consistently. They explain why this happens: “The involvement of BA 10 in people praying frequently indicates that suppressing task-irrelevant activity is a crucial component of successful NF performance.” NF is short for Neurofeedback. It is defined as such: “Neurofeedback is a kind of biofeedback, which teaches self-control of brain functions to subjects by measuring brain waves and providing a feedback signal” (Marzbani). In simple terms, this is a means of measuring control over the individual’s thoughts and functions of the brain. This study discovered that prayer incorporates an area called the BA 10. This part of your brain is a component that many people can’t utilize very well. When Christians spend consistent time in prayer they unlock this area, giving them a great cognitive advantage! God designed the minds of his people to utilize this ability. God knew that by commanding prayer, his people would be able to control, strengthen, and rewire their brains. The most amazing part is that it doesn’t require difficult mastery and scientific knowledge. God simply asks his people to talk to him.
Prayer makes the subject happier. This is often emphasized in scripture, and it isn’t simply a mystical reality from God. Prayer physically changes the parts of the brain being used This leads to a release of happy hormones. In an article titled “The Neurobiological Link Between Prayer, Breath Control and Serotonin Release”, Shingo Ueda points out how prayer and serotonin release are connected. The author also makes the connection that breath control is often naturally incorporated in prayer. The author says that this pair of prayer and breath control stimulates the Parasympathetic Nervous System. This helps relax and regulate brain function. Ueda states that “prayer activates brain areas involved in emotional regulation, self-awareness, and cognitive control, including the prefrontal cortex, orbitofrontal cortex, and anterior cingulate cortex. These regions are also known to play a role in serotonin signaling and are implicated in mood regulation.” The study discovers what parts of the brain are being used and how they release serotonin in the brain. Why is this important? Well, serotonin is “a neurotransmitter, serotonin carries messages between nerve cells in your brain… and throughout your body… These chemical messages tell your body how to work” (Cleveland Clinic). It often dictates how one feels and how they function, as well as playing a great role in one’s well-being. The Cleveland Clinic also states: “Serotonin plays several roles in your body including influencing learning, memory, happiness as well as regulating body temperature, sleep, sexual behavior and hunger. Lack of enough serotonin is thought to play a role in depression, anxiety, mania and other health conditions.” When serotonin is kept at a healthy level, the body can regulate itself and stay happy. Staying in prayer will lead to a chemically happier brain, not just a fuzzy feeling. As a result of this release, learning, doing good, being successful, and all traits related to these are more likely to occur and provide the Christian with a blessed life.
There is another side to this equation of happiness. Along with making the brain happier, prayer makes the brain less sad. This might seem like an obvious observation, but it is very important to discuss. Prayer attacks depression at its roots. It does not simply cover it up with serotonin (happiness), it limits the very cause of bad feelings. This root cause is called high cortisol. The Hypothalamic-Pituitary-Adrenal (HPA) Axis Modulation is where the root is attacked. Ueda writes: “The HPA axis plays a key role in the body’s stress response. Chronic activation of the HPA axis leads to elevated cortisol levels, which impair neurogenesis in the hippocampus, an area of the brain rich in serotonin receptors… This suppression of neurogenesis is linked to the development of mood disorders such as depression.” Prayers limit this HPA axis’ activation, which lowers cortisol. When the cortisol is high, serotonin is blocked. When you allow cortisol to be regulated, serotonin can stay balanced and provide all the benefits listed previously. He further explains: “Research has shown that activities that engage breath control, such as mindfulness meditation and prayer, can reduce HPA axis activity, thereby lowering cortisol levels and promoting serotonin release.” Breath control is a big part of this process. It can be learned and mastered to multiply the effects of prayer. However, what Ueda explains in the study is that breath control is connected by default. Prayer does not just magically fix problems; it attacks every little piece that contributes to a struggling mental health. Prayer lowers the depressing hormones, which allows the happy hormones to be spread. This doesn’t just affect how one feels, but also how one functions. A happy life results in a successful one.
One of the most interesting studies on this subject is this one Harrison Carvour did. The study is titled “A Review of the Neuroscience of Religion”. He discovered something that will change every Christian’s relationship with God if they put it to action. Listen to what he says: “Personal prayer activates a network of brain regions involved with social cognition, including the temporopolar region, TPJ, precuneus, and MPFC. This activation emphasizes the similarity between praying to God and non-religious human communication, as prayer involves viewing God as an intentional agent of reciprocation.” He found that prayer activates the same regions that talking to a friend activates. This can be pivotal for every spiritual life. God literally designed the brain to become connected to him and respond in ways like we would with a friend (Carvour). This is something most Christian’s struggle with. People want to feel closer to God. If they spend adequate time in prayer, they will start experiencing a real connection that is comparable to their physical relationships. James 4:8 says, “Draw near to God, and he will draw near to you” (ESV). Closeness with God can be felt, if we do it his way.
Time to Change Your Life
How does one apply what he has learned? How does one truly transform their life? The research has already been presented. Prayer does indeed make remarkable changes. Still, there is the question of how do we utilize prayer? The best way to begin is by forming the habits needed to sustain constant renewal. Habits are directly connected to this idea of neuroplasticity. When you do something repeatedly, it creates a pathway of defaulting to that action. This is going to benefit every Christian in two ways. First, one can develop a habit of consistent prayer that becomes automatic in their daily life. Second, this new habit will leverage all aspects of prayer that were discussed earlier in this paper. Gayle Beebe stated in his article “How Faith and Prayer Benefit the Brain” that “engaging in 12 minutes of personal reflection and prayer each day makes a profound impact on our brain.” This might not seem like much in theory, but twelve minutes is a long time for one to focus their attention. So, to achieve such a habit and state of control, we must start small.
The gold standard for habit development has become a book titled “Atomic Habits” by James Clear. This book is utilized by most successful businessmen, preachers, speakers, or anyone desiring to grow. He studied the brain and how it functions and gave a basic and simple application to leverage your brain’s ability. These methods are one and the same as the research this paper has described. One method he taught can be a great tool to achieve this state of consistent prayer. Start with two minutes. Pray for two minutes. The individual can do this once, twice, or as many times desired each day. When this becomes a consistent add time to the routine. Pray two minutes each session for a week. Then increase the time to three minutes, four minutes, and so on. Clear says, “A new habit should not feel like a challenge.” This is going to pave the neural pathway in the brain. Once that pathway is paved, it can be widened. The highway can be deepened by adding more time (Clear 162). It will only be a matter of weeks before this habit becomes an automatic part of ones life.
To stay consistent with a new habit, it needs to be tracked. Creating a habit tracking system will allow one to stay consistent. James Clear says this about tracking habits: “Habit tracking also helps keep your eye on the ball: you’re focused on the process rather than the result” (Clear 198). This is tremendously important when trying to grow. When Christians try to grow, they often focus too much on seeing results. This leads to becoming discouraged and giving up. If the individual can become obsessed with the process, the results will be far greater in the end.
In his sermon at Polishing the Pulpit 2024, Greg Dismuke gave a sermon that changed how everyone thought about prayer. He said to “find a praying place” (Dismuke). A private place will provide opportunity to focus and create a pathway in the brain. When one enters that place, they know it is time to focus the mind and talk to God. This place is not going to limit where prayer can take place, but it will be a dedicated spot for deep thinking and reflection. He referenced Matthew 6:6 in the sermon as his base text: “But when you pray, go into your room and shut the door and pray to your Father who is in secret. And your Father who sees in secret will reward you” (ESV). This verse gives a tip to the one who wants a relationship with God. When you create a specific place for certain tasks in your home, your mind will default more easily to concentration in those places. Clear states: “One of the most effective ways to reduce the friction associated with your habits is to practice environment design” (Clear 153). This is what Dismuke is drawing from the scriptures. It also makes one intentional about the action. Intention plays a great role in the success of one’s habits. Praying in a secret place will achieve the greatest level of intimacy, concentration, and meditation.
Prayer is quite possibly the most powerful blessing in Christian walk. It is the direct connection to the one who made everything in existence. The one who sustains life. This God invites you to talk to him. When you seek him, he draws close to you. To thrive in this world of pain, suffering, and temptation you must utilize the divine power of the transcendent God. Prayer is commanded and constantly stressed in the inspired word of God. These studies prove that God designed the brain to work in extraordinary ways. He created the physical and the spiritual to work in a beautifully orchestrated harmony. Lastly, he made it easily accessible to harness this great power of prayer. The one thing you must do to rise to a mental capacity above all in this world, is “pray without ceasing” (1 Thessalonians 5:17, ESV).
