How To Prepare For A Fast

There are many things you can do to prepare for a fast. Many of these are important so please read this to be sure you maximize your fasting benefits.

“And do not present your members as instruments of unrighteousness to sin, but present yourselves to God as being alive from the dead, and your members as instruments of righteousness to God.”

– Romans 6:13

All scriptures are taken from the NKJV unless otherwise noted.

Mentally Prepare

The mind is extremely powerful and our attitude toward our fast has a great impact on whether or not it’ll be successful. When we think about our fast, we should be confident it’s the will of God for us and that He’ll bless us for being obedient. Don’t rely on your feelings when it comes to fasting. Just like everything else, we’re obedient in fasting because God tells us to be and we have the power of the Holy Spirit to help us.

But you, when you fast, anoint your head and wash your face, so that you do not appear to men to be fasting, but to your Father who is in the secret place; and your Father who sees in secret will reward you openly.”

– Matthew 6:17-18

This scripture reveals a promise of God. If we fast with the right motive and in the correct way, God will openly reward us. Therefore, you’d be depriving yourself of the very best if you do not fast. God can’t reward you if you don’t meet the requirements of the promises of scripture.

Hebrews 11:6 tells us that it’s impossible to please God without faith. Our attitude toward fasting must be one of faith.

Promises Of Fasting

“Is this not the fast that I have chosen:
To loose the bonds of wickedness,
To undo the heavy burdens,
To let the oppressed go free,
And that you break every yoke?
Is it not to share your bread with the hungry,
And that you bring to your house the poor who are cast out;
When you see the naked, that you cover him,
And not hide yourself from your own flesh?
Then your light shall break forth like the morning,
Your healing shall spring forth speedily,
And your righteousness shall go before you;
The glory of the Lord shall be your rear guard.
Then you shall call, and the Lord will answer;
You shall cry, and He will say, ‘Here I am.’

“If you take away the yoke from your midst,
The pointing of the finger, and speaking wickedness,
If you extend your soul to the hungry
And satisfy the afflicted soul,
Then your light shall dawn in the darkness,
And your darkness shall be as the noonday.
The Lord will guide you continually,
And satisfy your soul in drought,
And strengthen your bones;
You shall be like a watered garden,
And like a spring of water, whose waters do not fail.
Those from among you
Shall build the old waste places;
You shall raise up the foundations of many generations;
And you shall be called the Repairer of the Breach,
The Restorer of Streets to Dwell In.”

– Isaiah 58:6-12

This scripture reveals many promises to those who fast in the correct way. These promises are:

  • health
  • light
  • glory
  • righteousness
  • answered prayer
  • satisfaction
  • continual guidance
  • satisfaction
  • work that endures
  • refreshing
  • restoration

Why would any believer in Christ not want to take part in those benefits? These are specifically promised to anyone who would fast in accordance with God’s will. By using the power of faith to fast, we are obeying the Word of God and He will reward us.


Temple Of The Holy Spirit

Or do you not know that your body is the temple of the Holy Spirit who is in you, whom you have from God, and you are not your own? For you were bought at a price; therefore glorify God in your body and in your spirit, which are God’s.”

– 1 Corinthians 6:19-20

The body we call home is not ours, it’s God’s. When Jesus redeemed us from death, He redeemed our whole self, including our bodies. Therefore, it’s not okay to neglect our bodies.

It deeply troubles me that some people don’t care at all about how they treat their bodies. God cares and a healthy body is necessary for the working of God’s Kingdom. The Holy Spirit dwells within us. This is the place where God decided to send the Holy Spirit to live.

If God gave us a physical temple to worship Him in, wouldn’t we be sure to take good care of it? Wouldn’t we make sure the parking lot is clean and the ceilings aren’t dusty? Our bodies are worth way more than a real building.

Unfortunately, many Americans have no basic understanding of nutrition. It saddens me because people often make themselves sick without knowing it because of the stuff they’re putting in their bodies. On the contrary, many Americans take real pride in their worldly possessions.

I know people who are extremely unhealthy with amazing, fabulous cars. If they treated their cars the same way they do their bodies, their car wouldn’t run. While you can always buy a new car, you cannot buy a new body. So please, take care of your body.

Fasting is a wonderful way to keep your body healthy if you do it correctly.


If you have some sort of medical disorder, please don’t fast unless you speak with your doctor first. There are some people who have to regularly take medicine or cannot go extended periods without food. For example, diabetics must keep their blood chemistry at a certain level.

In this case, other Christians should fast for these people.

When you fast, protect yourself from constipation. Before and after fasting, eat foods that will promote healthy bowel movements such as fruit, vegetables, oatmeal, fruit juices, etc.

Also, don’t attempt to abstain from fluids for any more than 72 hours. That’s extremely dangerous and I would recommend against it 100%.

In order to prepare for a fast, there are quite a few things you can do. However, the most important thing is to prepare your mindset to be successful. Also, be sure to fast in faith, knowing it’s the Will of God for your life. Therefore, you should expect God to reward you for your obedience according to Isaiah 58.

There are people who cannot fast and that’s okay. Don’t try to fast if you have medical conditions unless your doctor tells you it’s okay.

Be sure to protect yourself from constipation by eating fiber-filled foods before and after fasts.

Abstaining from liquids is extremely dangerous. I wouldn’t recommend it.
