Unlocking Spiritual Breakthroughs: The Power of Fasting in Deepening Your Faith

1,497 words, 8 minutes read time.

Fasting is one of the most ancient spiritual disciplines, yet many Christians today either overlook it or misunderstand its purpose. In a world where convenience and comfort reign supreme, the idea of voluntarily going without food—or any other necessity—can seem extreme. But throughout history, fasting has played a critical role in spiritual growth, drawing believers closer to God, strengthening prayer, and deepening faith in ways that few other practices can.

Jesus Himself fasted for forty days before beginning His public ministry (Matthew 4:2), and He taught His followers, “When you fast…” (Matthew 6:16), not if you fast, implying that fasting should be a natural part of a believer’s life. But why is it so powerful? How does it actually help in spiritual growth? And how can modern Christians practice fasting in a way that brings real transformation? Let’s explore the role of fasting in spiritual growth, looking at biblical foundations, personal benefits, and practical ways to incorporate it into your life.

Fasting in the Bible: A God-Ordained Discipline

Fasting has deep roots in Scripture, spanning both the Old and New Testaments. It was a common practice among God’s people, often associated with repentance, seeking divine intervention, or preparing for a new spiritual season. In the Old Testament, Moses fasted on Mount Sinai before receiving the Ten Commandments (Exodus 34:28). Daniel fasted for 21 days, eating no rich foods, seeking understanding from God (Daniel 10:2-3). Queen Esther called for a national fast when her people were in danger (Esther 4:16). Each instance shows fasting as more than just skipping meals—it was about humbling oneself before God and seeking His presence.

In the New Testament, Jesus set the ultimate example by fasting for forty days in the wilderness, preparing for His mission (Matthew 4:1-2). The early church practiced fasting as well, particularly when seeking God’s guidance. Acts 13:2 records, “While they were worshiping the Lord and fasting, the Holy Spirit said, ‘Set apart for me Barnabas and Saul for the work to which I have called them.’” Fasting, then, is not just an ancient custom but a tool God has given us to grow spiritually, seek His will, and align our hearts with His purposes.

Why Fasting Deepens Your Relationship With God

One of the most profound reasons fasting accelerates spiritual growth is that it shifts your focus from the physical to the spiritual. When you fast, you intentionally deny the body’s cravings, reminding yourself that you are not ruled by your flesh but by the Spirit.

John Piper, in his book A Hunger for God, writes: “Christian fasting, at its root, is the hunger of a homesickness for God.” In other words, fasting is not about earning favor with God or proving our spirituality—it’s about creating space to long for Him more than we long for food, entertainment, or anything else.

Fasting also strengthens prayer. The Bible shows that when people fasted, their prayers carried extra weight. Daniel fasted and prayed for insight, and God responded by sending an angel with revelation (Daniel 10:12). When the disciples struggled to cast out a demon, Jesus told them, “This kind does not go out except by prayer and fasting” (Matthew 17:21, NKJV). There is a mysterious yet undeniable power that comes when fasting is combined with prayer.

Additionally, fasting exposes and uproots hidden sins. When you deprive the body of its usual comforts, you begin to see things you might otherwise ignore—bad habits, thought patterns, or even heart issues like pride or impatience. As Jentezen Franklin explains in his book Fasting: Opening the Door to a Deeper, More Intimate, More Powerful Relationship With God, “Fasting breaks you down, revealing the areas in your life where you are still holding on to control.”

Different Types of Fasting and How to Choose the Right One

Not all fasting looks the same. In fact, the Bible describes different types of fasting, and Christians today practice fasting in various ways depending on their spiritual needs and physical abilities.

One of the most common fasts is the normal fast, where a person abstains from all food but drinks water. This is the kind of fast Jesus undertook in the wilderness. Then there’s the partial fast, seen in Daniel 10, where Daniel refrained from eating rich foods but still ate simple meals. The absolute fast, like the one Esther called for, involves abstaining from both food and water, but this is typically short-term due to health concerns.

Beyond food, many believers today practice non-traditional fasts, such as fasting from social media, television, or other distractions to focus more on God. The key is choosing a fast that challenges you spiritually while being mindful of your physical health.

How to Fast Effectively Without Falling into Legalism

One of the biggest mistakes people make with fasting is turning it into a religious duty rather than a heartfelt pursuit of God. Jesus warned against fasting for show, saying, “When you fast, do not look somber as the hypocrites do, for they disfigure their faces to show others they are fasting” (Matthew 6:16). The goal of fasting is not to impress others or earn spiritual “points” but to humble yourself before God and grow in intimacy with Him.

Before starting a fast, it’s important to set a clear purpose. Are you fasting to seek God’s guidance? To break a bad habit? To intercede for someone? Having a goal will keep your fast spiritually focused rather than just feeling like a diet.

Prayer and Scripture should also accompany fasting. If you’re skipping meals but not spending extra time with God, you’re just starving yourself. Fasting creates space for deeper prayer, and reading passages like Isaiah 58—the chapter where God explains true fasting—can keep your heart aligned with Him.

Breaking a fast properly is just as important as starting one. If you’ve gone without food, reintroduce meals slowly. More importantly, carry the spiritual lessons you’ve learned into daily life so fasting isn’t just an event but a transformative practice.

Fasting in Church History: How Christians Have Used Fasting for Centuries

Throughout church history, fasting has been a vital practice for Christians seeking revival and closeness with God. Early church fathers like Augustine, Athanasius, and John Chrysostom emphasized fasting as a means of purifying the soul. The monastic movements of the Middle Ages incorporated fasting into their disciplines, and even reformers like Martin Luther and John Wesley practiced and promoted fasting.

Wesley, in particular, would not ordain anyone into ministry unless they fasted twice a week, believing it was essential for spiritual leadership. Today, fasting remains an integral part of many Christian traditions, from the Catholic observance of Lent to corporate fasts in Pentecostal and evangelical circles.

Common Challenges and How to Overcome Them

Fasting isn’t easy. The hunger pains, fatigue, and irritability can make it tempting to quit. One of the biggest misconceptions is that fasting should always feel deeply spiritual, but in reality, it can be uncomfortable. However, every time you feel hunger, it’s an opportunity to refocus on God.

Health concerns can also be a challenge. If you have medical conditions, fasting should be done with wisdom—consider partial fasting or non-food fasts. Additionally, if you find yourself treating fasting like a performance or growing frustrated when you don’t feel immediate spiritual breakthroughs, remind yourself that fasting is a process, not a magic formula.

Conclusion: Embracing Fasting as a Lifelong Discipline

Fasting isn’t just an ancient religious practice; it’s a powerful way to grow closer to God, deepen your prayer life, and align your heart with His will. It requires discipline and sacrifice, but the rewards are worth it. Whether you’re seeking clarity, breakthrough, or simply a deeper hunger for God, fasting can be a transformative spiritual tool.

As Jentezen Franklin puts it, “When you give up what you crave, God gives you what you need.” If you’ve never fasted before, consider starting small and allowing God to lead you into a deeper experience of His presence. Your spiritual growth will never be the same.
