What is Spiritual Fasting? And Why Should I Fast?

finds.life • 3 minutes

When we spiritually fast, we deny ourselves things we love for something we love even more. Christians fast as a spiritual practice to deepen their relationship with God. Fasting is often done to connect with God, seek His guidance, and grow in humility.

Fasting can take many forms, such as taking a break from eating certain foods, social media, or other things we enjoy. The goal of fasting is to grow in our relationship with God. 

Fasting is often connected to prayer and meditation. It can also be a way to learn self-control, humility, and to practice self-discipline. 

What Does the Bible Say About Fasting?

Biblical fasting, unlike fasting for medical or health reasons, must be done with an attitude of seriousness and sincerity. When we fast, we willingly deprive the body of nourishment and the pleasurable taste of food. The body requires food for sustenance; therefore, our hearts and minds must be totally focused and directed toward God so that He may be the full source of our strength during our period of fasting.

Our hearts and minds must be totally focused and directed toward God so that He may be the full source of our strength during our period of fasting.

Fasting isn’t a performance for God or others. It’s an act of humble worship, so do your best to keep your fast a secret. It’s not necessary for others to know we are fasting; it is directed toward God.

But when you fast, put oil on your head and wash your face, so that it will not be obvious to men 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. Matthew 6:17-18

We should fast to further the building up of God’s kingdom by seeking to minister to others.

In addition to our attitudes toward God and our stance before man, our motives must also be correct. We should fast to further the building up of God’s kingdom by seeking to minister to others. The prophet Isaiah received from the Lord the acceptable motives for our fasts. 

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 him, and not to turn away from your own flesh and blood? Isaiah 58:6-7

How Should We Fast?

Fasts may last for varying lengths of time–one day, three days, seven days, or more. We should prayerfully seek the Lord about the length of our fast. Fasting should have an object in mind; we should have a clear idea of the need and purpose.

5 Practical Steps for Spiritual Fasting

1. Jesus, Only Jesus

Fasting is primarily a spiritual activity, not a dieting exercise.

There’s no spiritual benefit to just not eating. So don’t get too caught up in the details of what (you’re fasting) and forget the why (deeper intimacy with Christ).

That’s why I recommend a food and reverse fast.

In short, a reverse fast is when you intentionally make time during your day to seek God more than you would typically. Where people tend to spend most of their time focused on the food aspect of a fast, a reverse fast reverses the priorities and places them on God.

It’s been, by far, one of the more practical things I’ve done to increase spiritual engagement during a fast.

2. Focus Your Fast

Biblical fasting always accompanied a specific spiritual reason.

You may be facing a major decision or seeking a fresh start in life. You may also be feeling distant from God and want to grow closer to Him. 

Write down 1-3 main things you’re praying and believing God for during your fast. Be bold. Dream.

Give the fast a reason to matter personally and spiritually to you. Spend time praying for these things, listening for God’s direction (if applicable), reading related Bible verses, etc. 

By fasting, you are engaging in a spiritual battle.

Know what you’re fighting for. It provides purpose and motivation. When you have a reason for going into battle, you’ll fight harder, longer and with more passion.

 3. 100%, Not 98%

Right now, commit to yourself and God that you’re going to honor your chosen fast 100% of the time. Not 98% or any other number lower than 100%.

Why?

Let’s be honest: when you make an exception due to “extenuating circumstances,” the odds of you completing the fast go down drastically. If you justify doing it “just this once,” there’s nothing keeping you from doing it again.

When “cheating” on a fast, 99 out of 100 times it’s not a valid decision. It’s a lack of discipline.

The next couple tips will help you stay at 100%.

And even if you do drop below 100%, start over again that day. You’re now back at 100%. God extends grace. Take it. 

4. Make an Allowed List

Make a list of the foods you’re allowing yourself to eat and only eat foods from that list. And be specific. Specific types of foods (e.g., apples, bananas) within specific food groups (e.g., fruit).

Do this before you start your fast. Alternatively, make a list of fast-approved recipes and only eat those recipes during the fast.

Inevitably, you will ask yourself the question: Is this allowed? I guarantee you’ll ask that question multiple times as you’re presented with catered work lunches, dinner out with friends, or cooking at home.

The list is designed to make that decision extremely easy, saving your time and energy for much more important things – seeking God (remember #1).

On the list, eat it (yum). Not on the list, nope.

And as you’re making the list, don’t get too caught up in the details of what’s allowed or what’s not in XYZ fast. For example, do whole grains include whole-grain pasta or just whole-grain rice? It doesn’t matter. Put it on the list, or don’t. You choose for yourself.

Fasting is a discipline, not a diet. Focus on the discipline of fasting, not the food you’re fasting.

Create a daily calendar. Every day, every meal, answer the question: What are you going to eat?

Again, it’s all about making decisions at the start, which drastically reduces the number of stressful game-time decisions. Game-time decisions are often when you’re the most tired, have the least amount of energy, and have zero willpower to stick to your fast.

Cook as many meals in one marathon cooking session as you can. Store it and have it ready to eat when you need it.

5. Plan, Plan, Plan

Identify potential roadblocks. Where in your schedule will you run into some challenges during the fast? Maybe it’s a work party or out-of-town travel.

What are you going to do in those situations. See #3. Stick to your fast.

You can create a detour now that you know where the roadblocks are. Pack your meal for those occasions. Have something ready to eat when you arrive at a roadblock.

Remember Your "Why"

With all these practical tips, let’s not forget why we’re fasting in the first place. The benefit of fasting is getting to know Jesus more intimately and see His Holy Spirit work in our lives on a much greater level.

How can we do that?

Spend more time in prayer, worship, and the Word. You created margin for those things with a reverse fast, right?

Those three things should be staples of your spiritual diet. Want those things just as much as you want food. Oh, and don’t forget to give God an opportunity to speak. Be intentional about listening for His voice and the Holy Spirit’s promptings.

Spiritual fasting is hard. You’ll be tempted. You’ll feel like a failure at times. Embrace your weakness because Christ’s power is made perfect in it (2 Corinthians 12:9).

Fasting enables the Holy Spirit to reveal your true spiritual condition, resulting in brokenness, repentance, and a transformed life.

Fasting changes us. It breaks down the idols in our lives. Forces a reliance on God. Brings about humility.

But you know what the cool thing is?

Even though it changes us, fasting (in God’s goodness) can also lead to answered prayers.

Ezra 8:23, "So we fasted and petitioned our God about this, and he answered our prayer."

That’s humbling and also demonstrates the spiritual significance of fasting. Let this verse motivate you to honor your fast, seek Him more and pray for bold things!

If you choose to fast from food, make sure you’re drinking plenty of water throughout your fast. If there’s a medical reason why you can’t fast from food, choose a different kind of fast.

Types of Fasts

  • Full Fast: Drink only liquids (you establish the number of days).

  • Three-Day Fast: This fast can be a full fast or giving up at least one item of food.

  • Partial Fast: A partial fast is 6:00am-3:00pm, or from sunup to sundown. You can select from three types of fasting—a Full Fast, Daniel Fast or giving up at least one item of food.

  • Media Fast: Eliminate any choice of media influence–television, movies, Internet, gaming systems, cell phones, etc.
