Prayer and Fasting: A Biblical Guide to Practicing Both

TL;DR
- Prayer and fasting appear together throughout Scripture as a way God's people humble themselves and seek His will.
- Jesus assumed His followers would fast, but He warned against doing it for show (Matthew 6:16-18).
- Fasting without prayer is just a diet; prayer without fasting can lose the physical reminder of dependence.
- The goal is not to earn God's favor but to realign your heart with Him.
- If you're in a season where fasting feels unwise, God's presence holds you just as firmly.
What Scripture Actually Says About Prayer and Fasting
The Bible never treats fasting as an optional add-on for extra-spiritual people. It shows up when God's people face major decisions, confess sin, mourn, or seek deliverance. Always, fasting is paired with prayer. The empty stomach points toward an open, dependent heart.
Here are a few passages that anchor the practice, each with a short look at what it meant in context.
| Verse | What It Says | How It Applies |
|---|---|---|
| Matthew 6:16-18 | Jesus tells His followers not to look somber or disheveled when they fast. The Father who sees in secret will reward them. | Check your motives. Fasting is for God's eyes, not a human audience. |
| Acts 13:2-3 | While the church in Antioch was worshiping, fasting, and praying, the Holy Spirit set apart Barnabas and Saul for mission. | Fasting can be part of how a community listens for God's direction before big steps. |
| Daniel 9:3 | Daniel turned to the Lord with pleading, prayer, fasting, sackcloth, and ashes as he confessed his people's sin. | Fasting gave weight to Daniel's confession and intercession. |
| Joel 2:12 | "Return to me with all your heart, with fasting, with weeping, and with mourning." | Fasting is a physical way to say "I mean this" when you come back to God. |
| Esther 4:16 | Esther asked the Jews in Susa to fast for three days before she risked approaching the king uninvited. | In moments of crisis, fasting can help a whole community cry out together for protection and courage. |
| Ezra 8:23 | Ezra proclaimed a fast at the river so they would humble themselves before God and ask for a safe journey. | Fasting is a way to declare that your safety and provision depend on God, not your own resources. |
These verses don't prescribe a rigid schedule. They do show a pattern. When God's people sensed urgency, grief, or the need for clear guidance, they often set aside food to set their attention on Him.
Why This Comes Up
Prayer and fasting arise in seasons of desperation, decision, and repentance. They also come up because many churches host fasting weeks or Lenten practices, and people wonder if they're doing it right. Others wrestle with whether fasting matters at all. Fasting is one entry in a much longer list of habits that shape a life of faith, and The Spiritual Disciplines: A Practical List for Everyday Faith walks through how it fits alongside the others.
In a quieter way, the question surfaces when we feel distant from God and suspect that our usual rhythms need a shake-up. Some people hear about fasting and worry it will become about performance. That fear is healthy because Jesus named it plainly: hypocrites make their fasting visible to others (Matthew 6:16). But His answer wasn't "don't fast." It was "do it differently."
Technology adds its own layer. AI companions now enter the spiritual conversation, and you might wonder if a digital tool can help you pray or guide you through a fast. Our look at Creed vs. Selah: Two Christian AI Companions, Compared walks through how different approaches handle Scripture. And we've written separately about why Selah doesn't let you role-play talking to Jesus. Prayer goes to God, not a machine. Tools can help you reflect on the Bible, but they are not the object of your worship.
Still, the question remains: what do I actually do with prayer and fasting in my ordinary life?
What This Looks Like Day to Day
Start small. Many believers have never fasted, and the body can panic at the idea of skipping a meal. That's normal. A beginning practice might look like this.
Pick a single day and choose what you'll fast from. Most traditions involve food, but if you have a medical condition or a history of disordered eating, please talk with a doctor or counselor before skipping meals. Fasting is not a biblical command to harm yourself. You can also fast from something that occupies your mind excessively, like social media, and dedicate that time to prayer.
During the fast, anchor your day around a few prayer times. Read a short passage aloud before you eat (or before you would have eaten). Use the physical hunger or the urge to reach for your phone as a prompt: "Lord, I want You more than I want this." A prayer journal can be a natural companion for a fasting day — a place to write down what surfaces once the usual distractions are stripped away.
Let the day be simple. You aren't proving anything. You're just setting aside one normal appetite so a deeper hunger can speak. Some people like to pair fasting with a written prayer list or a psalm. Psalm 69:10 says, "I wept and humbled my soul with fasting." That's the tone.
Remember that if you're battling depression, fasting can feel overwhelming or even destabilizing. You are not failing if you choose not to fast right now. Scripture holds out comfort for weary minds. The post on Bible Verses About Depression and God's Comfort sits alongside this conversation, not against it.
A Few Ways People Get This Wrong
One mistake is treating fasting as a way to force God's hand. Isaiah 58 makes it sharp: people fasted and then exploited their workers and fought each other. God ignored the fasting because it wasn't attached to obedience and mercy. Fasting doesn't twist God's arm. It opens your own.
Another mistake is turning fasting into a spiritual résumé. Posting about it online for admiration, silently comparing who fasts longer, or feeling superior to others is the show Jesus warned against. If you wouldn't tell someone you're fasting, good. If you must tell someone (a spouse or a roommate who needs to know why you aren't eating), keep the explanation brief and unimpressed with yourself.
A third mistake is going through the motions while your heart stays distant. The body goes without lunch but the mind scrolls. The stomach growls and you treat it like an annoyance, not an invitation to pray. That pattern leads to frustration and abandoning the practice entirely. Fasting is meant to make space for honest conversation with God. If that space fills with noise, the fast collapses into mere hunger.
On the opposite end, some people fear fasting because they grew up in traditions that used it as a punishment or a guilt trigger. Fasting in Scripture is never a lash. It's a voluntary humbling that Jesus Himself practiced (Matthew 4:2). The same Jesus taught John 3:16, a declaration of God's love that invites you to draw near, not hide. That love is the ground under your fasting, not a reward you win.
Loneliness during a fast is real. You might feel isolated if you practice it alone while everyone around you eats. The Bible reminds you that God is present. The post on Bible Verses About Loneliness and God's Presence can be a companion on a day when the quiet feels heavy.
A Short Prayer or Reflection to Sit With
Father,
I come to You with an ordinary day and an ordinary heart. I don't know how to fast well, and I bring that to You too.
You said in Joel, "Return to Me with all your heart, with fasting." I turn my heart toward You now. Whatever I set aside today, I want You to fill that space.
If I'm hungry, remind me that You are my bread. If I'm distracted, pull my thoughts back gently. I'm not trying to impress anyone. I'm not trying to twist Your arm. I'm just asking for a clearer view of You.
Thank You that Your love doesn't rise and fall with my discipline. You loved me before I skipped a meal, and You'll love me when I eat again.
In Jesus' name, Amen.
