๐Teaching Kids the Spiritual Discipline of Fasting
Fasting is one of the most powerful yet misunderstood spiritual disciplines. In our culture of constant consumption and immediate gratification, teaching children to voluntarily abstain from food or other pleasures seems almost countercultural. Yet Scripture presents fasting as a normal practice for God's people, a way to humble ourselves, focus on God, and seek His face with intensity and intentionality (Matthew 6:16, Isaiah 58:6, Acts 13:2).
The challenge: How do we introduce this ancient practice to modern kids? How do we teach fasting in age-appropriate, SAFE ways that draw children closer to God without harming their developing bodies? How do we cultivate a heart that hungers for God more than food (Psalm 42:1)? The answer: Start small, prioritize safety, emphasize the HEART behind fasting (not just the act), and model it ourselves. Fasting = powerful tool for spiritual growth when taught biblically and practiced wisely.
"When you fast, do not look somber as the hypocrites do, for they disfigure their faces to show others they are fasting. Truly I tell you, they have received their reward in full. But when you fast, put oil on your head and wash your face, so that it will not be obvious to others that you are fasting, but only to your Father, who is unseen; and your Father, who sees what is done in secret, will reward you."
โ Matthew 6:16-18 (NIV)
๐Biblical Foundation: Why and How We Fast
- โขMatthew 6:16-18 - Fasting in secret, not for show: 'When you fast, do not look somber as the hypocrites do... But when you fast... do it in secret; and your Father, who sees what is done in secret, will reward you.' Fasting = PRIVATE spiritual discipline, not public performance. We don't fast to impress people, we fast to seek GOD. Teach kids: Fasting = between you and God.
- โขIsaiah 58:6-7 - The fast God chooses: 'Is not this the kind of fasting I have chosen: to loose the chains of injustice... to share your food with the hungry and to provide the poor wanderer with shelter?' True fasting = connected to JUSTICE, compassion, service. Not just abstaining FROM food, but using that sacrifice to bless OTHERS. Fasting should produce FRUIT in how we treat people.
- โขJoel 2:12-13 - Fasting with sincere heart: 'Return to me with all your heart, with fasting and weeping and mourning. Rend your heart and not your garments.' God cares about HEART, not external ritual. Fasting without genuine repentance/seeking God = meaningless. Teach kids: It's not WHAT you give up, but WHY. Heart attitude matters.
- โขActs 13:2-3 - Fasting when seeking God's will: 'While they were worshiping the Lord and fasting, the Holy Spirit said, 'Set apart for me Barnabas and Saul...' So after they had fasted and prayed, they placed their hands on them.' Early church fasted when making BIG decisions, seeking God's guidance. Fasting = helps us HEAR God's voice more clearly (fewer distractions).
- โขMatthew 17:21 - Some things require prayer and fasting: 'This kind does not go out except by prayer and fasting' (NKJV). Some spiritual battles, breakthroughs require MORE than casual prayer, they require INTENSITY of fasting + prayer. Fasting = weapon in spiritual warfare (Ephesians 6:12).
- โขPsalm 35:13 - Fasting in intercession: 'I put on sackcloth and humbled myself with fasting.' Fasting = form of HUMILITY before God, often done when interceding for others. Physical hunger reminds us of our spiritual need for God. Teach: When we fast, we're saying 'God, I need YOU more than food.'
Key Takeaway
๐ถTeaching Fasting by Age (Safety First!)
๐กPractical Guidelines for Teaching Fasting
โ Action Items
ALWAYS prioritize SAFETY over spiritual experience
Health comes first. (1) Medical clearance: Consult pediatrician before ANY food fasting, especially if child has health conditions, (2) Age-appropriate: NO food fasting for kids under 9. Focus on non-food sacrifices (screens, toys, desserts), (3) Watch for warning signs: Dizziness, weakness, irritability, headaches = STOP immediately, (4) Hydration essential: Water always allowed (and encouraged!) during food fasts, (5) NEVER if: Eating disorder history/risk, diabetes, growth concerns, pregnant/nursing. Better to err on side of caution, spiritual discipline should NEVER harm physical health.
Connect fasting to PRAYER (not just dieting)
Fasting without prayer = just skipping meals. (1) Clear PURPOSE: 'We're fasting and praying for [specific need], healing, guidance, revival, etc.,' (2) Prayer focus: When hunger pangs come, PRAY instead of eating, 'God, I need you more than food,' (3) Replace meal time with Bible reading/worship: Use time you'd spend eating to seek God, (4) Family prayer: If fasting together, gather during meal times to pray as family, (5) Isaiah 58 reminder: Fasting should produce FRUIT, compassion, justice, service. If fasting makes us grumpy/proud, we're missing the point.
Start SMALL and build gradually (don't overwhelm)
Spiritual muscles need training. (1) Progression: Dessert fast โ screen fast โ partial meal โ full meal โ full day (over YEARS, not weeks), (2) Age-appropriate: What's appropriate for teen โ appropriate for 7-year-old, (3) Success breeds success: Better to complete SHORT fast joyfully than fail at TOO-LONG fast, (4) Non-food first: Master giving up screens, toys, entertainment BEFORE attempting food fasts, (5) Celebrate completion: 'You fasted AND prayed! God sees your heart!' Reinforce spiritual victory.
Emphasize HEART attitude, not legalism
Pharisees fasted legalistically, Jesus wants hearts. (1) Matthew 6:16-18: Fasting = secret between you and God, not public badge of honor, (2) Avoid pride: 'I fasted for 3 days!' = wrong attitude. Humility = 'God, I desperately need you,' (3) Grace for 'failure': If child can't complete fast, that's OKAY, 'You tried! What did you learn about your need for God?,' (4) Joel 2:13: 'Rend your HEART, not your garments', God cares about inner transformation, not external performance, (5) Purpose matters: WHY are you fasting? To seek God? Or to feel spiritual? Check motives.
MODEL fasting yourself (kids imitate what they SEE)
You can't teach what you don't practice. (1) Share (appropriately): 'I'm fasting today because I'm seeking God about [decision/need],' (2) Don't make it burdensome: If you complain about fasting, kids will see it as miserable, (3) Let them see fruit: 'God answered my prayers during that fast! He gave me clarity/peace/breakthrough,' (4) Family fasts: Occasionally fast TOGETHER, powerful bonding + spiritual experience, (5) Matthew 6:17-18: 'Wash your face', don't look miserable. Fasting should be joyful discipline, not drudgery.
Teach DIFFERENT types of fasting (not just food)
Fasting = giving up ANYTHING to focus on God. (1) Food: Traditional, abstaining from meals to pray, (2) Media: Screens, social media, entertainment, replace with Bible/prayer, (3) Activities: Sports, hobbies for a season, redirect time to God, (4) Comfort: Warm bed, favorite snacks, luxuries, practice simplicity, (5) Daniel fast: Only fruits/vegetables (Daniel 1:12), healthier option for longer fasts, (6) Partial: One meal, certain foods, specific times, easier for beginners. Fasting = sacrifice of SOMETHING we value to prioritize GOD.
Connect to SCRIPTURE and church history (not weird, NORMAL)
Fasting = biblical, historical practice. (1) Jesus fasted: Matthew 4:2, 40 days before ministry began, (2) Early church fasted: Acts 13:2, 14:23, seeking God's will, appointing leaders, (3) Old Testament examples: Moses, David, Esther, Daniel, Nehemiah, all fasted, (4) Church history: Christians have fasted for 2000+ years, Lent, corporate fasts, personal disciplines, (5) Not weird: 'Fasting is NORMAL for Christians. It's how we seek God intensely.' Normalize the practice.
"Is not this the kind of fasting I have chosen: to loose the chains of injustice and untie the cords of the yoke, to set the oppressed free and break every yoke? Is it not to share your food with the hungry and to provide the poor wanderer with shelter, when you see the naked, to clothe them, and not to turn away from your own flesh and blood?"
โ Isaiah 58:6-7 (NIV)
๐ฉบSafety Comes Before Everything
โ Good fits for children
- โขScreen and media fasts (TV, games, phone, social media)
- โขGiving up dessert, candy, or a favorite snack for a set time
- โขSetting aside a toy, hobby, or comfort for a day
- โขA Daniel-style fast of simple foods (fruits and vegetables) for older kids, with a doctor's blessing
- โขSkipping a single meal for a preteen or teen who is healthy and medically cleared
โNot appropriate for children
- โขMulti-day fasts without food
- โขAny food fasting for kids under nine
- โขFasting that continues after warning signs appear
- โขWater-only fasts imposed as punishment or willpower tests
- โขAny fast for a child with an eating-disorder history, diabetes, or growth concerns
๐ซCommon Mistakes Parents Make
- โขTurning fasting into a willpower contest. 'Let us see how long you can go' aims at the wrong target. Fasting is about seeking God, not proving grit. Keep the purpose in front of the child at every step.
- โขSkipping the prayer. A fast without prayer is just a hungry, grumpy child. The hunger is meant to be a doorbell that says 'turn to God right now.' If you remove the prayer, you remove the point.
- โขPushing food fasts too early. A seven-year-old's body is busy building bone and brain. Let young children practice with screens, sweets, and toys. Save food fasting for older, healthy kids and clear it with a doctor first.
- โขPraising the performance. When a child announces 'I fasted three whole days,' gently redirect. We are cultivating humility, not a badge. Celebrate the heart that sought God, not the size of the sacrifice.
- โขShaming a child who cannot finish. If a fast is cut short, that is not a failure of faith. 'You tried, and you leaned on God, that matters' keeps the door open instead of tying guilt to a spiritual discipline.
๐ฌReal Conversations You Can Actually Have
๐When your child asks: Why would God want me to be hungry?
Reframe it right away. "God does not enjoy your empty stomach. He loves your heart. When we set something aside for a little while, the empty feeling reminds us to talk to Him. It is like a string tied around your finger that says, 'Do not forget, God is here and I need Him.'" For younger children, tie it to a non-food fast so the lesson lands without any hunger at all.
๐คWhen your child says: This is too hard, I want to quit.
Meet them with grace, not pressure. "You do not have to earn anything by finishing. God already loves you completely. Let us pray right now and then decide together." If it is a food fast and the child is genuinely struggling, feeding them is the right call. A short fast finished in peace teaches far more than a long one endured in misery.
๐When your child brags: I fasted longer than my friend.
Use the moment to teach Matthew 6. "Jesus told us to fast in secret, just between us and God. When we compare, we make it about us instead of Him. Next time, let us keep it quiet and let it be our little secret with God." No shame, just a gentle turn back toward humility.
"My soul thirsts for God, for the living God. When can I go and meet with God?"
โ Psalm 42:2 (NIV)
โQuestions Parents Ask
At what age can my child skip a meal?
What if my child has anxiety or a complicated relationship with food?
Is it hypocritical to teach fasting if I struggle with it myself?
โ Your Next Steps This Week
โ Action Items
Pick one clear reason to fast as a family this month (a sick friend, a big decision, or simple gratitude) and write it where everyone can see it.
Start with a non-food fast: choose a screen-free evening and fill the freed-up time with prayer, reading, or serving someone together.
If you are considering any food fast for a child, book or call your pediatrician first and get their blessing before you plan anything.
Teach your child one short prayer to say whenever they notice the thing they gave up, so hunger or boredom becomes a cue to talk to God.
Model it yourself: tell your child, in age-appropriate terms, one thing you are setting aside this week and why, then let them see the fruit afterward.
Key Takeaway
"Then Jesus was led by the Spirit into the wilderness to be tempted by the devil. After fasting forty days and forty nights, he was hungry."
โ Matthew 4:1-2 (NIV)
