Why Should Christians Fast?

The Bible gives us many reasons why we should fast as Christians. If you’re sensing God pull you in the direction of a fast, I’ll explain why Christians should fast for spiritual purposes.

All scriptures are taken from the NKJV unless otherwise noted.

To Humble Oneself

“I humbled myself with fasting…”

– Psalm 35:13

In Psalm 35, King David claims that he humbled himself through fasting. God asks us repeatedly throughout the Bible to humble ourselves. This is something God expects us to do in obedience to Him. He claims He will exalt those who humble themselves. (Matthew 23:12)

If you want God to exalt you, then you must humble yourself.

The Lord lifts up the humble;
He casts the wicked down to the ground.”

– Psalm 147:6

Gain Instruction And Direction From God

“Then I proclaimed a fast there at the river of Ahava, that we might humble ourselves before our God, to seek from Him the right way for us and our little ones and all our possessions.”

– Ezra 8:21

Fasting and praying is a wonderful way to seek God’s face. He promises us that if we acknowledge Him in all our ways, He will direct our paths. (Proverbs 3:6) Therefore, if you take the time to pray and fast, humbling yourself, God will certainly show you the direction He wants you to go.

Fasting can quiet the world around you and allow you to hear God more clearly, which is important before making any big decisions in your life.

To Seek Healing

Then your light shall break forth like the morning,
Your healing shall spring forth speedily…”

– Isaiah 58:8

In my last blog post, How To Prepare For A Fast, I went through eleven different promises found in the Word of God about fasting. They are found in Isaiah chapter 58. One of these promises is health.

This can also be applied to the suffering one experiences from a demonic spirit. In Matthew 17, Jesus healed a boy from epilepsy. When His disciples asked why they couldn’t cast out the demon, Jesus responded, Because of your unbelief; for assuredly, I say to you, if you have faith as a mustard seed, you will say to this mountain, ‘Move from here to there,’ and it will move; and nothing will be impossible for you. However, this kind does not go out except by prayer and fasting.”

Jesus’ ministry was mainly one of healing and deliverance. Before His ministry officially started, He fasted for forty days and forty nights. Jesus is our example and God says “the servant is not greater than the master.” (John 13:16) If Jesus fasted, shouldn’t we?

To Understand God’s Word More Clearly

“Draw near to God and He will draw near to you.”

– James 4:8

While fasting, you’ll find out that your head is more clear than normal and it gives you the ability to understand God’s Word deeper with great concentration. This alone is a wonderful reason for fasting.

The Need For Divine Intervention

“And Jehoshaphat feared, and set himself to seek the Lord, and proclaimed a fast throughout all Judah.”

– 2 Chronicles 20:1-3

In 2 Chronicles chapter 2, Jehoshaphat found himself in a scary predicament. Large armies were collectively coming to invade his kingdom from Ammon, Mount Seir, and Moab. At the time, he was the king of Judah. Upon hearing this distressing news, he proclaimed a fast throughout his entire kingdom.

Every woman, man, and child was included in this fast. During their period of fasting, the enemies turned on each other and slaughtered one another. The kingdom of Judah didn’t have to lift a single weapon! The only thing they had to do was collect the spoil afterward. There were so many valuable items that it took them three whole days to collect them all.

God is still the same today. He can do anything He desires and when we seek Him, it shows that we’re looking to Him and Him alone to answer our prayers.


To Pray And Intercede On Behalf Of Others

If you’re concerned about someone you love who doesn’t know God or who is not saved, fasting and praying on their behalf will greatly benefit them. It expresses to God that you’re willing to sacrifice something of yours for someone else. In addition to that, it takes great faith to do a sacrificial action for someone you love.

If you’re going to fast and pray for a loved one (or with any objective in mind), I recommend making a list of things you’re praying for. You’ll be completely astonished when you look back throughout the years at all the prayers God has answered.

Submit To The Holy Spirit

“But I discipline my body and bring it into subjection, lest, when I have preached to others, I myself should become disqualified.”

– 1 Corinthians 9:27

In Romans 8:7, Paul says the carnal mind is enmity against God. The flesh is ruled by emotion and feelings. However, if we want the power of the Holy Spirit, we must crucify the flesh. We have to rule over it or else we’ll become a slave to it.

Self-discipline is not an easy accomplishment, but it is one of the fruits of the Holy Spirit. (Galatians 5:22-23) Every Christian has to ask themselves: Am I controlled by my body or do I control my body? Fasting is not easy at first and really tests our ability to say no to the flesh.

As you continue to say no to the flesh, the Holy Spirit will get stronger within you.
