Humility Before God
Fasting is Scripture's language of humbling the soul (Psalm 35:13). It quietly reminds you that you do not live by bread alone, but by every word from God's mouth.

Biblical Fasting: How to Fast
A beginner-friendly guide to what fasting is, why Scripture calls us to it, and how to do it wisely.
Fasting is one of the oldest and most misunderstood practices in Scripture. This guide explains the spiritual purpose of fasting, the main biblical approaches, a simple step-by-step method for your first fast, and how to keep praying once the hunger sets in.
WHAT FASTING IS
Fasting is making room, not going without.
Biblical fasting is choosing to set aside food — or another legitimate comfort — for a defined time in order to give focused attention to God.
Throughout Scripture fasting appears at moments of decision, danger, grief, and dedication. Moses, David, Esther, Daniel, Anna, Jesus, and the early church all fasted. What they shared was not a technique but a posture: a deliberate lowering of self so that prayer could take the front seat.
That is why fasting is never presented as a way to earn God’s attention or to pressure Him into acting. Jesus assumed His followers would fast — “when you fast,” not “if you fast” (Matthew 6:16) — and He tied it to sincerity rather than performance. Fasting empties the hands so they can be lifted.
“Even now, declares the LORD, return to me with all your heart, with fasting and weeping and mourning.” — Joel 2:12
THE SPIRITUAL PURPOSE
Six reasons Scripture connects fasting to prayer.
Repentance & Return
Joel 2:12 calls God's people to return with fasting, weeping, and mourning. Fasting gives repentance a body — it turns sorrow over sin into deliberate action.
Clarity & Direction
In Acts 13:2–3 the church fasted and prayed before sending out leaders. Fasting quiets competing appetites so that God's direction becomes easier to recognize.
Intercession & Breakthrough
Esther called a three-day fast for a nation at risk (Esther 4:16). Fasting often accompanies prayer for situations larger than ourselves.
Spiritual Strength
Jesus fasted forty days before His public ministry (Matthew 4:1–2). Fasting trains the will to say no to lesser things so it can say yes to God.
Compassion & Justice
Isaiah 58 ties true fasting to feeding the hungry and loosing burdens. A biblical fast always looks outward as well as upward.
COMMON BIBLICAL APPROACHES
Five types of fasts found in Scripture.
Choose the approach that fits your health, your season, and your commitments. A smaller fast kept faithfully is worth far more than an ambitious one abandoned.
Partial Fast
Abstaining from food for part of the day — for example sunrise to sunset — and eating a simple meal afterward. The most common entry point for beginners.
Daniel 9:3
Selective (Daniel) Fast
Eliminating specific foods rather than all food. Daniel ate only vegetables and drank water, refusing rich food and wine for a set period.
Daniel 1:12; 10:2–3
Normal Fast
Abstaining from all food while continuing to drink water, usually for one day or a defined number of days.
Matthew 4:1–2
Corporate Fast
A congregation, family, or community fasting together over the same period with shared prayer focus.
Joel 2:15–16; Esther 4:16
Non-Food Fast
Setting aside media, entertainment, social platforms, or spending. Appropriate when a food fast is unwise for health reasons — and valuable for everyone.
1 Corinthians 7:5
HOW TO FAST
Seven practical steps for your first fast.
1. Decide the What and the How Long
Name it before you start: one meal, one day, three days, sundown to sundown, or a specific food or habit. An undefined fast usually ends in confusion or guilt.
2. Give the Fast a Prayer Focus
Write two or three prayer points. Fasting without a focus becomes dieting; fasting with a focus becomes intercession.
3. Prepare Your Body
Taper heavy meals, caffeine, and sugar a day or two ahead. Keep drinking water throughout unless a physician has advised otherwise.
4. Replace the Meal, Don't Just Skip It
Use the time you would have spent eating for Scripture, prayer, worship, or silence. That exchange is the point of the discipline.
5. Keep It Quiet
Jesus taught that fasting is for your Father, not for an audience (Matthew 6:16–18). Tell only those who need to know.
6. Break the Fast Gently
Return with something light — fruit, soup, or vegetables — before a full meal, especially after longer fasts.
7. Write Down What God Said
Record impressions, Scriptures, and answers. A journal turns a single fast into a record of God's faithfulness you can return to.
WHAT TO AVOID
Common mistakes beginners make.
- Fasting to impress God or other people rather than to seek Him.
- Starting with an extended fast before your body or prayer life is ready.
- Skipping water, or ignoring medical guidance and warning signs.
- Filling the freed-up hours with screens instead of Scripture and prayer.
- Treating one hard day as failure — restart rather than abandon the season.
- Fasting while refusing to forgive or to act justly (Isaiah 58:6–7).
A Note on Health
Fasting should be approached responsibly. Children, pregnant or nursing individuals, older adults, and people managing medical conditions, medications, eating disorders, or specialized dietary needs should consult an appropriate licensed healthcare professional before participating in a food-based fast. A non-food fast is a valid alternative. The purpose of fasting is never to harm the body or to earn God's love.
FREQUENTLY ASKED
Questions people ask before their first fast.
What is biblical fasting?
Biblical fasting is voluntarily setting aside food, or another legitimate comfort, for a set period of time in order to give focused attention to prayer, repentance, Scripture, and seeking God. In Scripture it is never a hunger strike against God or a way to earn His favor — it is a way of humbling yourself and making room for Him.
How do I start fasting as a beginner?
Start small and specific. Choose one meal or one day, decide in advance what you are fasting from and what you will pray about, drink water, and use the time you would have spent eating to read Scripture and pray. Then build gradually as your body and your prayer life adjust.
How long should a fast be?
There is no required length. Scripture records fasts of part of a day, one day, three days, seven days, and forty days. Beginners do well with a single meal or a sunrise-to-sunset fast. Extended fasts should only be undertaken with preparation and appropriate medical guidance.
Can I fast if I have a health condition?
Not without guidance. Children, pregnant or nursing individuals, older adults, and anyone managing a medical condition, medication schedule, eating disorder, or specialized diet should consult a licensed healthcare professional first, and can choose a non-food fast instead — media, entertainment, spending, or another comfort.
What should I pray about while fasting?
Give your fast a focus: repentance, direction, a family member, healing, a decision, a breakthrough, your church, or your nation. Write two or three prayer points before you begin so hunger becomes a prompt to pray rather than a distraction.
