Fasting isn’t just an ancient religious ritual—it’s a powerful spiritual practice that Jesus taught, modeled, and expected His followers to embrace. In the Bible, Jesus made it clear that fasting should be done sincerely, privately, and with a clear purpose. He fasted Himself before launching His ministry and emphasized that fasting, when paired with prayer, brings spiritual clarity, strength, and even breakthrough in tough situations.
Today, fasting still matters. It cuts through the noise, refocuses your heart on God, and helps break unhealthy habits and spiritual stagnation. Whether you’re seeking guidance, dealing with a struggle, or just want to grow closer to God, fasting is a practical, impactful step. Keep reading for a deeper dive into what Jesus said, why it still matters, and how to fast effectively in today’s world.
Fasting has been a key spiritual practice for thousands of years. But what did Jesus actually say about fasting? And more importantly—why does it still matter today?
Let’s break it down.
What Is Fasting in the Bible?
In simple terms, fasting is voluntarily going without food (and sometimes drink) for a period of time to focus on God. It’s a way to humble yourself, seek clarity, repent, or intercede for others.
But biblical fasting isn’t just about skipping meals. It’s deeply tied to prayer, repentance, and spiritual growth.
What Did Jesus Say About Fasting?
Jesus didn’t just mention fasting in passing—He gave clear instructions and even fasted Himself.
1. Jesus Fasted
Before He began His public ministry, Jesus fasted for 40 days in the wilderness.
“After fasting forty days and forty nights, he was hungry.” – Matthew 4:2 (NIV)
This wasn’t just about physical discipline. It was a spiritual preparation. Jesus resisted temptation, connected with God, and set the tone for His ministry.
2. Jesus Expected His Followers to Fast
Jesus didn’t say if you fast—He said when.
“When you fast, do not look somber as the hypocrites do… But when you fast, put oil on your head and wash your face.” – Matthew 6:16-17 (NIV)
Notice the word “when”. Jesus assumed fasting would be a regular part of a believer’s life. But He made it clear—fasting isn’t about looking religious or impressing others.
3. Fasting Should Be Private and Sincere
Jesus emphasized that fasting should be between you and God, not for public show.
“…your Father, who sees what is done in secret, will reward you.” – Matthew 6:18 (NIV)
He criticized those who made fasting a performance. Real fasting is humble, honest, and God-focused.
4. Fasting for Power and Breakthrough
In Mark 9:29, after His disciples failed to drive out a demon, Jesus said:
“This kind can come out only by prayer and fasting.” (Some translations include “and fasting,” others don’t, but the principle is clear.)
Fasting, paired with prayer, brings spiritual power and breakthrough.
Why Does Fasting Still Matter Today?
So why should you care? You’re not living in first-century Israel. You’re juggling work, family, stress, and more.
But here’s the truth: fasting still matters. In fact, it may be more important in today’s distracted, comfort-driven world.
Here’s why:
1. Fasting Sharpens Your Focus on God
Life is noisy. Phones buzz. Schedules overflow. Fasting helps clear out the clutter so you can hear from God more clearly.
- It slows you down.
- It re-centers your priorities.
- It reminds you that man doesn’t live on bread alone (Matthew 4:4).
2. Fasting Builds Spiritual Strength
When you deny your body, your spirit gets stronger.
You learn self-control. You become more aware of your spiritual hunger. You stop being ruled by cravings and start living with intention.
3. Fasting Helps with Repentance and Humility
In Scripture, people often fasted when they were grieving their sin or seeking God’s mercy.
- David fasted after sinning with Bathsheba (2 Samuel 12:16).
- The people of Nineveh fasted in response to Jonah’s warning (Jonah 3:5).
- Ezra fasted in mourning and prayer (Ezra 10:6).
Today, fasting still serves as a way to humble yourself before God and seek a clean heart.
4. Fasting Can Break Strongholds
Are you stuck in a bad habit? Addicted? Battling fear or doubt?
Fasting creates space for God to move. It invites breakthrough.
Remember Isaiah 58:6:
“Is not this the kind of fasting I have chosen: to loose the chains of injustice and untie the cords of the yoke…?”
Fasting isn’t a magic trick. But it’s a powerful spiritual weapon.
How to Fast the Way Jesus Taught
So how do you do it?
Here’s a simple guide to fasting the way Jesus intended:
1. Start with Purpose
Don’t fast just to check a spiritual box. Ask:
- Am I seeking clarity?
- Do I need breakthrough?
- Am I repenting?
- Do I want to grow closer to God?
2. Choose the Type of Fast
There are several biblical ways to fast:
- Complete fast – No food, just water (typically short-term).
- Partial fast – Like the Daniel Fast (no meats or sweets).
- Time-based fast – Skip one or two meals a day.
- Digital/social fast – Giving up media or distractions (not biblical, but helpful today).
Start small. Maybe fast one meal and spend that time in prayer.
3. Stay Focused on God
Pray, read Scripture, journal. Fasting without prayer is just a diet.
4. Be Discreet
As Jesus said, don’t make a big deal out of it. Keep your fasting between you and God.
Final Thoughts: Fasting Is a Tool, Not a Burden
Jesus never intended fasting to be a guilt trip. It’s not about earning points with God. It’s about drawing close to Him, realigning your heart, and walking in spiritual power.
And in today’s world—where distraction, indulgence, and spiritual dullness are everywhere—fasting might be one of the most relevant things you can do.
So ask yourself:
What do I need to lay down to hear God more clearly?
And remember Jesus’ words:
“Your Father, who sees what is done in secret, will reward you.” – Matthew 6:18
That reward? It’s not fame, fortune, or applause. It’s deeper intimacy with Him. And that’s worth more than anything you’ll ever miss during a fast.
