In a world of constant notifications, endless food delivery options, and instant gratification, the idea of voluntarily giving up food feels almost ancient. Yet Christians across the centuries have found fasting to be a powerful way to draw closer to God. It's not about earning favor or showing off spiritual discipline—it's about creating space for God to speak and transform us.
Before we dive into how to fast, we need to address the common pitfalls. The Bible gives us clear warnings about wrong motives and attitudes. Once we understand those, the path to meaningful fasting becomes much clearer.
Three Common Mistakes to Avoid
1. The Mistake of Neglect
The most widespread error today is simply not fasting at all. Many Christians have never tried it, or they've relegated it to a past era. We live in a culture that encourages indulgence, and skipping meals feels counterintuitive. But Jesus assumed his followers would fast. In Matthew 9:15, he said, “The days will come when the bridegroom is taken away from them, and then they will fast.” The early church took this seriously—Acts 13:2-3 describes believers fasting before sending out Paul and Barnabas.
When we neglect fasting, we miss out on a gift. It's not about suffering for its own sake; it's about redirecting our hunger toward God. Psalm 42:1-2 captures this longing: “As a deer pants for flowing streams, so pants my soul for you, O God. My soul thirsts for God, for the living God.” Fasting can awaken that thirst.
2. The Mistake of Boasting
If we do fast, pride can creep in. It's easy to feel superior for practicing a discipline others ignore. Jesus directly addressed this in Matthew 6:16-18: “And when you fast, do not look gloomy like the hypocrites, for they disfigure their faces that their fasting may be seen by others. Truly, I say to you, they have received their reward. But when you fast, anoint your head and wash your face, that your fasting may not be seen by others but by your Father who is in secret. And your Father who sees in secret will reward you.”
The reward we seek is not human approval but God's presence. Fasting becomes a private conversation between you and God, not a public performance. If we find ourselves wanting others to notice our sacrifice, we've already lost the heart of the discipline.
3. The Mistake of Ritual Without Relationship
Another danger is turning fasting into a mere religious obligation. Going through the motions without a heart connection to God misses the point entirely. Isaiah 58 gives a powerful critique of empty fasting: “Is not this the fast that I choose: to loose the bonds of wickedness, to undo the straps of the yoke, to let the oppressed go free, and to break every yoke?” (Isaiah 58:6). True fasting is linked to justice, mercy, and humility before God.
If we fast but ignore the needs around us, or if we fast without prayer and reflection, we're just dieting. Fasting is meant to align our hearts with God's heart—and that always leads to love for others.
How to Fast with Purpose
Start Small and Seek Guidance
If you're new to fasting, begin with a single meal or a partial fast (like skipping lunch and spending that time in prayer). The goal is not to prove your endurance but to focus on God. Choose a specific purpose: pray for a family member, seek wisdom for a decision, or intercede for your church or community.
You can also fast from something other than food—social media, television, or other distractions. The principle is the same: set aside a normal comfort to devote that time to God. 1 Corinthians 10:31 reminds us, “So, whether you eat or drink, or whatever you do, do all to the glory of God.” Fasting is one way to bring glory to God by prioritizing him.
Pair Fasting with Prayer and Scripture
Fasting without prayer is just hunger. Use the time you would have spent eating to read the Bible, journal, or sit in silence before God. The Psalms are a great place to start—they express the full range of human emotion and can guide your prayers. For example, Psalm 63:1 says, “O God, you are my God; earnestly I seek you; my soul thirsts for you; my flesh faints for you, as in a dry and weary land where there is no water.” Let those words become your own.
You might also focus on a specific passage or theme. If you're fasting for healing, meditate on Psalm 103:2-3: “Bless the Lord, O my soul, and forget not all his benefits, who forgives all your iniquity, who heals all your diseases.” If you're fasting for guidance, Proverbs 3:5-6 is a classic: “Trust in the Lord with all your heart, and do not lean on your own understanding. In all your ways acknowledge him, and he will make straight your paths.”
Listen to Your Body and Your Spirit
Fasting is a spiritual discipline, but it also affects your physical health. If you have medical conditions, consult your doctor before starting. Pregnant or nursing women, those with diabetes, or people with eating disorders should approach fasting with caution or choose a different type of fast.
Pay attention to how your body responds. If you feel weak or dizzy, it's okay to break the fast early. The goal is not to harm yourself but to humble yourself before God. Remember that God looks at the heart, not the duration of your fast.
Practical Steps for a Meaningful Fast
Here are a few suggestions to help you get started:
- Set a clear intention. Write down why you are fasting and what you hope to see God do. This keeps you focused when hunger strikes.
- Choose a specific time frame. It could be from sunrise to sunset, 24 hours, or a few days. Be realistic about your schedule and commitments.
- Plan your prayer times. Instead of just skipping meals, schedule prayer breaks. Use a Bible reading plan or a list of prayer requests.
- Stay hydrated. Drink water during your fast. If you're doing a full fast, water is essential.
- Break your fast gently. When you end your fast, eat light foods first. Your body needs time to adjust.
Above all, remember that fasting is a means of grace, not a way to manipulate God. It's an invitation to draw near to him, and he promises to draw near to us (James 4:8).
Frequently Asked Questions
What does the Bible say about fasting?
The Bible mentions fasting in both the Old and New Testaments. It was practiced by Moses, David, Daniel, and Jesus himself. Jesus gave instructions on how to fast in Matthew 6, and the early church fasted before important decisions. Fasting is always connected to humility, prayer, and seeking God's will.
Can I fast if I have health issues?
Yes, but with caution. Consult your doctor before starting any fast, especially if you have diabetes, heart conditions, or a history of eating disorders. You might consider a modified fast (like the Daniel fast of vegetables and water) or fasting from something other than food.
How long should I fast?
There is no biblical mandate for a specific duration. Start with a short fast—one meal or one day—and see how God leads. Some people fast regularly, like once a week, while others fast for longer periods during special seasons. The length is less important than the attitude of your heart.
A Final Reflection
Fasting is not about proving your spirituality or earning God's favor. It's about creating space in your life for God to work. When you feel hunger pangs, let them remind you to pray. When you miss the comfort of food, let that longing turn into a deeper hunger for God.
Consider this question: What would it look like for you to set aside one meal this week to seek God? Could that small sacrifice open the door to a deeper relationship with him? The early church found fasting to be a source of strength and guidance. Perhaps it's time for us to rediscover that gift.
