Key points
01Why Did We Stop Fasting?
Fasting is often viewed as an extreme measure today, yet it was once a completely normal part of everyday life. We need to ask ourselves how we lost touch with such a foundational practice. In our modern culture, we are surrounded by an endless abundance of food. From brightly lit supermarkets to twenty-four-hour drive-through windows, society has organized itself around constant consumption. We eat three large meals a day, supplement them with numerous snacks, and celebrate almost every social occasion with heavy feasting. Because of this societal shift, the mere idea of skipping a meal can feel incredibly radical, even frightening, to the average person. But Derek Prince challenges this modern comfort zone by taking us directly back to the foundational texts of the Christian faith to show that fasting was never meant to be optional. If you look closely at the Sermon on the Mount in the Gospel of Matthew, Jesus lays out the basic expectations for his followers. He speaks about giving to the poor, praying, and fasting. The specific language Jesus uses is highly revealing. He does not say, "If you give," or "If you pray." He explicitly says, "When you give," "When you pray," and "When you fast." Prince highlights this passage to point out a glaring inconsistency in modern religious practice. Most believers accept that giving and praying are non-negotiable pillars of a faithful life. Yet, somehow, fasting has been pushed aside, treated merely as an extreme activity meant only for spiritual giants or ancient monks. By removing fasting from our regular routines, we have effectively stripped away one-third of the fundamental equipment Jesus provided for spiritual growth. To fully grasp the importance of this lost art, we have to look at the historical context of the early believers. The early Christians did not have the luxury of convenience, yet they made fasting a regular, disciplined part of their weekly schedules. They understood that the physical body and the spiritual life are deeply intertwined. When the church needed to make a major decision, such as sending out Paul and Barnabas on their missionary journeys, they did not just hold a committee meeting. They worshipped, they prayed, and they fasted. They intentionally denied their physical appetites to ensure their spiritual senses were razor-sharp. They wanted to hear clear directions from God without the static of physical comfort getting in the way. How often do we find ourselves facing massive life decisions—career changes, relationship struggles, financial crises—and yet we only offer a quick prayer before moving on with our day? Prince argues that our lack of fasting directly correlates with our lack of spiritual power and clarity. We treat our bodies like engines that we never turn off, constantly fueling them and expecting them to run perfectly. Fasting is the deliberate act of hitting the reset button. It is a conscious decision to step away from the noise of the dinner table and the distraction of the refrigerator to focus entirely on a higher purpose. Furthermore, we must distinguish between a modern diet and a true biblical fast. This is a crucial distinction that Prince makes very clear. Today, intermittent fasting is incredibly popular for weight loss, longevity, and cellular health. While those physical benefits are very real and scientifically proven, a biblical fast has a completely different primary objective. A diet focuses almost exclusively on the physical body—how you look, how you feel, and what the scale says. A biblical fast, on the other hand, focuses entirely on your relationship with the divine. The physical benefits are merely a wonderful byproduct of a spiritual discipline. If you stop eating but do not direct your attention toward prayer, self-reflection, and seeking God, you are not truly fasting; you are simply starving yourself. The resistance to fasting is often deeply psychological. We have been conditioned to believe that hunger is an emergency. The moment our stomachs rumble, we feel an urgent need to fix the problem with a snack. Prince points out that this immediate gratification weakens our willpower and makes us slaves to our appetites. By rediscovering the practice of fasting, we reclaim our autonomy. We prove to ourselves that we are not controlled by our cravings. This realization alone is incredibly empowering. It shifts your perspective from being a consumer to being a master of your own physical domain. As we explore the depths of Derek Prince's teachings, we must approach the topic with an open mind and a willingness to challenge our daily habits. The loss of fasting in modern culture has left a void in our spiritual development. Filling that void requires intentional effort, education, and a desire to connect with something greater than our immediate physical needs. The journey back to this ancient discipline is not about punishing the body, but rather about liberating the soul from the heavy, lethargic chains of constant consumption.
02The Hidden Power of Humbling Yourself
There is a profound connection between our physical appetite and our spiritual pride. By denying the stomach, we actively train the soul to submit to a higher authority. Derek Prince places massive emphasis on the concept of humility, explaining that it is the absolute prerequisite for experiencing any significant spiritual breakthrough. In the modern world, humility is often misunderstood as weakness or a lack of self-esteem. However, in the biblical context, humility is a powerful, intentional act of lowering oneself to acknowledge dependence on God. And according to Prince, there is no more practical, tangible way to humble yourself than through the act of fasting. To understand this, we have to look at how intertwined human pride is with human appetite. Our most basic, primal drive is the desire for food. When we have easy access to food, we feel secure, self-sufficient, and in control. This sense of control can easily breed a subtle form of arrogance. We start to believe that we sustain ourselves through our own hard work and resources. Fasting physically breaks this illusion. When you voluntarily choose to stop eating, you force your body to experience weakness. You strip away your daily comforts and remind your physical frame that it is fragile and entirely dependent on the grace of God for survival. Prince Frequently references the words of King David in the Psalms, who wrote, "I humbled my soul with fasting." Notice the active nature of this statement. David did not wait for God to humble him through tragic circumstances or failures. He took the initiative. He actively chose a method to bring his own soul into a state of submission. Prince explains that God will not force humility upon us. We can pray for God to make us humble, but God’s response is usually to give us the opportunity to humble ourselves. Fasting is that opportunity. It is the physical mechanism through which we lower our pride and say, "My spiritual need for you is greater than my physical need for food." Let us explore what happens internally when we begin to fast. The moment you decide to skip a meal, your flesh—your natural, physical desires—begins to rebel. You might become irritable, restless, or frustrated. People often joke about being "hangry" hungry and angry, but Prince views this emotional reaction as a highly revealing diagnostic tool. When you get angry just because you missed a meal, it exposes who is truly sitting on the throne of your life. It shows that your physical appetites have been dictating your mood, your behavior, and your peace of mind. Fasting brings these hidden dependencies to the surface so they can be dealt with. Here are a few ways fasting actively breaks down our pride: It exposes our idols: We often use food for comfort, stress relief, and entertainment. Fasting reveals how much we rely on food rather than God for emotional support. It shatters self-reliance: Feeling physically weak reminds us that our strength is limited and temporary. It creates a vacuum for prayer: The time and energy usually spent preparing, eating, and digesting food is redirected toward seeking divine guidance. It silences the ego: When the body is quieted, the loud demands of the ego begin to fade, allowing the gentle voice of the spirit to be heard. Think of the relationship between your spirit and your flesh like a rider on a wild horse. The flesh is the horse—strong, driven by instinct, and constantly looking for the nearest patch of green grass to consume. The spirit is the rider, holding the reins and trying to direct the horse toward a specific destination. If the rider never pulls back on the reins, the horse will simply go wherever it wants, eating whatever it sees. Fasting is the act of pulling back hard on those reins. It is a firm declaration to the flesh that it is no longer in charge. The spirit is taking control. This process of humbling the soul is deeply transformative. When you approach God in a state of self-imposed weakness, you attract His grace. Prince points out the biblical principle that God resists the proud but gives grace to the humble. By fasting, you are essentially positioning yourself to receive that grace. You are removing the barriers of self-sufficiency that block spiritual growth. You are creating a clear, unobstructed channel for communication between yourself and the divine. Furthermore, this act of humbling is not meant to be a miserable, self-loathing experience. It is a joyful surrender. While the body may complain loudly in the beginning, the spirit begins to soar. The heavy burdens of pride, anxiety, and the need to constantly control your environment start to lift. You realize that you do not have to have all the answers, and you do not have to rely solely on your own strength. By humbling yourself through fasting, you tap into a reservoir of spiritual power that is far greater than anything you could generate on your own.
