This is Part 2 of a 6-part series on biblical fasting.

Have you ever noticed how hunger reveals what you really want? Skip breakfast, and by mid-morning you’re fixated on food. Miss lunch, and that meeting becomes an exercise in willpower as your stomach growls. Physical hunger commands our attention, exposing how much we depend on regular meals for focus, energy, and emotional equilibrium.

That’s not a flaw—it’s a feature. God created us to experience hunger because physical hunger teaches us about spiritual reality. When our stomachs are empty, we’re reminded that we’re creatures, not the Creator. We need provision. And that physical dependence points to a deeper truth: we need God even more than food.

Fasting leverages this design. It redirects natural hunger toward spiritual awareness. But before we can practice fasting wisely, we need clarity about what it actually is—and what it isn’t.

What Fasting Is NOT

Let’s start by clearing away the misconceptions. These false understandings either keep people from fasting altogether or turn fasting into something destructive rather than beneficial.

Not a Diet or Health Plan

Fasting involves abstaining from food, and yes, you’ll lose weight if you fast. But that’s not the point. If your primary motivation is weight loss, you’re dieting, not fasting biblically. Biblical fasting is voluntary abstinence from food for spiritual purposes. The focus isn’t your waistline; it’s your heart.

When we confuse fasting with dieting, we miss the point. Fasting isn’t about improving your body; it’s about exposing your heart.

Not a Way to Earn God’s Favor

This is crucial: fasting doesn’t make God love you more or pay closer attention to your prayers. You already have God’s full attention and perfect love because of Christ. Jesus’ righteousness covers you completely. There’s nothing you can add to what He’s already accomplished.

So why fast? Because we’re secure in God’s love, not to earn it. We fast as a response to grace, not a means to obtain it. Fasting is something children do who are confident in their Father’s love, not slaves working to gain a master’s approval. If you’re fasting to twist God’s arm or make Him more favorably disposed toward you, you’ve fundamentally misunderstood the gospel.

Not Manipulation or Spiritual Leverage

Fasting isn’t a technique for getting what you want from God. It’s not a spiritual hunger strike. That’s manipulation, not devotion.

God is sovereign. He doesn’t need you to fast to accomplish His purposes. Fasting doesn’t change God’s mind or force His hand. What it does is position your heart to receive what God wants to give. It creates space where there was clutter.

Not a Badge of Spiritual Superiority

Jesus condemned the Pharisees for precisely this distortion. They fasted twice a week and made sure everyone knew it. Their fasting became a public display of spiritual achievement, a way to establish themselves as more devoted than ordinary people. Look at Jesus’ warning:

“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.” (Matthew 6:16)

If you find yourself proud of your fasting, or judging others who don’t fast, or posting about your fast on social media to gain admiration, you’ve completely missed the point. True fasting is practiced in secret. It’s between you and God. The moment you start using it to impress people, you’ve exchanged genuine spiritual benefit for human approval. And as Jesus says, that approval is all the reward you’ll get.

What Fasting IS

Now that we’ve cleared away the counterfeits, let’s examine what Scripture actually teaches about fasting.

A Physical Expression of Spiritual Dependence

At its core, fasting is about dependence. When we voluntarily abstain from food, we’re making a physical statement: we need God more than bread. Look at how Scripture connects fasting with humility:

“But as for me, when they were sick, I wore sackcloth; I afflicted myself with fasting; I prayed with head bowed on my chest.” (Psalm 35:13)

The phrase “I afflicted myself with fasting” captures an important truth. Fasting deliberately embraces discomfort as a way of humbling ourselves before God. It’s a physical acknowledgment that we’re not self-sufficient. We need God.

This is why fasting and prayer go together in Scripture. When you fast, you use the time you would have spent eating to pray. Every hunger pang becomes a prompt to turn to God. Physical emptiness becomes a reminder of spiritual need.

A Tool for Exposing What We Truly Trust

When we remove food from the equation, we discover what we’ve been depending on for comfort and satisfaction.

What do you reach for when you’re stressed? Many of us head to the kitchen. What about when you’re bored or anxious? If your answer involves food (or entertainment, or social media, or shopping), fasting will expose that dependency.

Fasting doesn’t create these dependencies—they’re already there. It just reveals them. You might discover you’ve been using food to manage emotions, cope with stress, or fill time. Skip a few meals, and these patterns become clear.

That’s a gift, though it doesn’t feel like one. You can’t address dependencies you don’t acknowledge. Fasting pulls back the curtain.

A Means of Grace (Not a Work)

This distinction is vital. A “means of grace” is a channel through which God’s grace flows to us. Prayer is a means of grace. Scripture reading is a means of grace. Corporate worship is a means of grace. These aren’t works that earn God’s favor—they’re ways God has designed for us to receive what He freely gives.

Fasting fits in this category. It’s not a work that makes you righteous. You’re already righteous in Christ. But it is a discipline that positions your heart to receive from God. It’s like opening a window—the window doesn’t create the wind, but it does allow the wind to fill the room.

Look at how Joel describes the kind of fasting God desires:

“Yet even now,” declares the Lord, “return to me with all your heart, with fasting, with weeping, and with mourning; and rend your hearts and not your garments.” Return to the Lord your God, for he is gracious and merciful, slow to anger, and abounding in steadfast love.” (Joel 2:12-13)

Notice the order: return to God with fasting. The fasting isn’t separate from returning—it’s part of the return. It’s an expression of wholehearted turning back to God. And notice what motivates this return: not fear of punishment, but confidence in God’s gracious character. Fasting is a response to grace, not an attempt to earn it.

A Discipline That Creates Space to Hear God

We live noisy lives—constant stimulation, endless options. Even quiet moments get filled with scrolling or snacking. We’ve become experts at avoiding stillness.

Fasting interrupts that noise. When you remove food from your schedule, you suddenly have time. And in that space, you can be still, listen, and pay attention to what God might be saying.

This is why the early church fasted when seeking direction:

“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.’ Then after fasting and praying they laid their hands on them and sent them off.” (Acts 13:2-3)

The fasting created a posture of attentiveness. It quieted competing voices. It demonstrated seriousness about hearing God’s will.

The Biblical Pattern

Fasting isn’t a fringe practice—it’s woven throughout Scripture.

Old Testament Practice

Throughout the Old Testament, God’s people fasted in crisis, in preparation for battle, in grief over sin, and in seeking guidance. Moses fasted forty days on Sinai. David fasted when his child was sick. Esther called for a fast before approaching the king.

Interestingly, God only commanded one fast: the Day of Atonement. Every other fast was voluntary—God’s people chose to fast as a way of expressing dependence.

Jesus’ Assumption

Jesus doesn’t say “if you fast.” He says “when you fast.” He assumes His followers will practice this discipline, just as they’ll give and pray.

Jesus modeled it. Before beginning His public ministry, He fasted forty days. He didn’t need to earn the Father’s approval—He already had it. But fasting prepared Him. It positioned Him to resist temptation.

Early Church Practice

The early church continued fasting. They fasted when appointing elders (Acts 14:23) and seeking direction. Paul mentions it in his ministry (2 Corinthians 6:5; 11:27). This wasn’t legalistic—nowhere are Christians commanded to fast on a schedule. But it was a normal, expected practice.

The Heart Issue: Fasting Doesn’t Repair, It Reveals

Here’s the crucial point we need to grasp: fasting is diagnostic, not curative. It exposes what’s in your heart, but it doesn’t fix what’s wrong. Only the gospel repairs broken hearts.

When you fast and discover irritability, anxiety, cravings, or anger, those things aren’t caused by the fast—they were already there. You were just medicating them with food, comfort, and distraction. Fasting pulls back the curtain and shows you what you’ve been depending on.

That’s valuable because you can’t repent of what you don’t see. You can’t turn from false gods you don’t recognize. Fasting helps you identify the functional saviors you’ve been trusting: control, comfort, approval, achievement, pleasure. Once they’re exposed, you can bring them to the cross. You can confess that these things don’t satisfy. You can turn from them and trust Christ more fully.

But fasting itself doesn’t transform you. The Spirit transforms you as you see your need and turn to Christ. Fasting is the tool that helps you see; the gospel is the power that changes.

Application Points

1. Evaluate your current understanding of fasting. Based on what you’ve read, where have you been confused or misinformed? Are you treating fasting as a diet, a work to earn favor, or a way to impress others? Confess those distortions and embrace the biblical understanding.
2. Consider what might be exposed. If you couldn’t use food to cope with stress this week, what would surface? What emotions or cravings would you face? That’s not a reason to avoid fasting—it’s an invitation to let God show you where you need His grace.
3. Start preparing your heart. Even if you’re not ready to fast yet, begin noticing your relationship with food. Do you eat on schedule regardless of hunger? Do you use food to manage emotions? Is eating a way you reward yourself or cope with difficulty? Awareness is the first step.
4. Remember the gospel foundation. Before you ever consider fasting, settle this truth deeply in your heart: you already have God’s full love and approval in Christ. Fasting adds nothing to your standing before God. You fast from security, not to gain it.
5. Pray for right motives. Ask God to guard your heart against pride, performance, and people-pleasing. Pray that if and when you fast, it would genuinely be about dependence on Him, not about proving anything to anyone.

Reflection Questions

• What would going without food for one day reveal about what you depend on for comfort, energy, and emotional stability?
• How does understanding fasting as a means of grace (rather than a work) change your perspective on this discipline?

Next week, we’ll examine the five biblical purposes for fasting. Why do people in Scripture fast? What specific situations call for this discipline? We’ll discover that fasting isn’t just something we do randomly—it has clear purposes rooted in our relationship with God.

Until then, pay attention to your hunger. Even the ordinary hunger you feel between meals can teach you something about dependence. Let it remind you: you were made needy. And the One you need most isn’t found in your pantry.
