This bartering with God never sat well—fasting used as currency, hunger used as an argument. Today, it’s common to hear expressions like “fasting for confirmation,” “fasting for an answer,” “fasting for victory.” But deep down, there’s something unsettling about this logic: fasting so that God will confirm a decision that, most of the time, we have already made.
It’s the old habit of trying to use the spiritual to reinforce the emotional. A person decides, feels, plans—and only then seeks God, not to ask, but to validate. It’s been this way since the first fasts in biblical history.
The first fast mentioned in the Scriptures appears in Judges 20:18–28, during one of Israel’s darkest periods. The people were divided. An entire tribe—Benjamin—had protected criminals, and the others decided to wage war against them. The decision was born of pride and indignation, not divine direction. Even so, the text says:
“The Israelites went up to Bethel and inquired of God. ‘Who of us is to go up first to fight against the Benjamites?’ The Lord answered, ‘Judah shall go first.’”
(Judges 20:18)
They asked who should go—not if they should go. God answered, but He did not approve. It was as if He said, “You’ve already decided to fight, so go—and learn from the consequences.”
In the first battle, Israel lost 22,000 men. Then they wept. In the second, they lost another 18,000. It was only then, after the pain and mourning, that fasting appeared:
“Then all the Israelites, the whole army, went up to Bethel, and there they sat weeping before the Lord. They fasted that day until evening and presented burnt offerings and fellowship offerings to the Lord.”
(Judges 20:26)
The sequence is revealing: first, they acted, then they asked, and only then did they fast. This was the first fast recorded in the Bible, and it was born of human reaction, not divine inspiration. It was man trying to fix with hunger what he had ruined with haste.
God heard. But His response was not comfort—it was correction. They won, yes, but at the cost of nearly exterminating an entire tribe. The fast led them to military victory, but not to spiritual restoration. They won the war but lost part of the body.
This is the picture of the confirmation fast: it seeks answers, but rarely seeks repentance.
Israel wanted to confirm if God was still with them, not if they were still with God. They wanted favor, not communion. They wanted a heavenly “yes” to erase the human consequences. Fasting was a late, emotional, reactive resort—like lighting a candle after the fire has already spread.
How often do we do the same? How often do we fast not to hear God, but to convince Him? Not to discern, but to force a sign? The human heart is an expert at disguising anxiety as spirituality. And fasting, when it enters that space, becomes a pious performance of someone trying to bend heaven with sacrifice.
Centuries later, the Gospel shows a perfect contrast. In Matthew 4:1, we read:
“Then Jesus was led by the Spirit into the wilderness to be tempted by the devil.”
Jesus’ fast begins before the battle, and it is born of the Spirit’s direction. It’s not a reaction; it’s a consecration. While the people of Israel fasted after defeat, Jesus fasts before the mission.
Israel fasts to get confirmation of what they had already decided. Jesus fasts to confirm the Father’s will. Israel fasts in desperation. Jesus fasts in obedience.
This difference changes everything. One fasts to be heard; the other fasts to listen. One fasts for God to confirm; the other fasts for the heart to align. That’s why, when the enemy tempts Him, Jesus responds with the Word, not with need.
“Man shall not live on bread alone, but on every word that comes from the mouth of God.”
(Matthew 4:4)
Christ’s fast is not about lack; it’s about fullness. One who has intimacy doesn’t fast to get something; one fasts not to lose focus on God.
In Isaiah 58, God confronts a religious people who fasted to be seen, admired, or rewarded. They asked:
“Why have we fasted, and you have not seen?”
(Isaiah 58:3)
God responds sternly:
“Yet on the day of your fasting, you do as you please.”
(Isaiah 58:3)
In other words: their fast was self-centered. They afflicted their bodies but fed their egos. They fasted to look holy, not to become holy.
The Lord then redefines the true fast:
“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?”
(Isaiah 58:6)
The fast God receives is one that liberates, not one that negotiates. It’s one that opens the eyes, not one that seals the lips.
There are times when God allows man to receive what he asks for, to learn what he truly needs. In Numbers 11, the people complain about the manna and demand meat. God answers, but with judgment:
“You will not eat it for just one day, or two days, or five, ten or twenty days, but for a whole month—until it comes out of your nostrils and you loathe it.”
(Numbers 11:19–20)
God granted the request, but the answer came as correction. They tasted what they desired and realized it wasn’t a blessing; it was poison.
Similarly, there are fasts that God may allow, but He does not approve. He is not moved by hunger, but by repentance. When fasting is manipulation, God responds to expose the motive. When it is intimacy, God responds to reveal His will.
Fasting for goals can be legitimate, but the real starting point is different: intimacy. It is in the secret place of communion that the right prayers are born. Before asking for direction, one must seek presence. Before presenting plans, one must silence the heart.
Jesus explained this simply:
“But the time will come when the bridegroom will be taken from them, and on that day they will fast.”
(Mark 2:20)
The Christian fast is not about a transaction; it’s about longing. To fast is to miss the Bridegroom, to remember that the sweetest bread is His presence. In intimacy, fasting becomes worship. It is in this environment that prayers with a function naturally arise—but now, functions born of communion, not of the ego.
During this intimate fast, we pray:
- To discern decisions, not to force results;
- To intercede for others, not to secure our own path;
- To overcome addictions and patterns, not to feed desires disguised as spirituality.
These prayers are consequences of intimacy, not conditions for it. It is presence that generates the function, not the other way around.
There is a subtle danger when a believer starts looking for verses to support what they already want to do. It’s what is now called “confirmation bias”—and it is spiritual as well. Instead of listening to God, we search for texts that confirm our will. But true fasting is precisely the opposite: it is silencing one’s own argument.
That’s what Jesus did in Gethsemane. Even with His body in agony and His soul overwhelmed, He prayed:
“Father, if you are willing, take this cup from me; yet not my will, but yours be done.”
(Luke 22:42)
Therein lies the spirit of the true fast: submitting one’s own will to God’s will. The hunger is physical, but the function is spiritual. The silence of the stomach helps to hear the sound of the Spirit.
The true altar of fasting is not the breadless table; it is the quieted heart. It is when the body learns to be silent so the spirit can speak. God is not moved by automatic sacrifices, but by contrite hearts. As the Psalmist says:
“My sacrifice, O God, is a broken spirit; a broken and contrite heart you, God, will not despise.”
(Psalm 51:17)
When the focus shifts from what I want to what God wants, the fast changes direction—and begins to ascend. It is not abstinence that moves heaven; it is obedience. An empty stomach does not convince God; a humble heart invites Him to remain.
The first fast in the Bible was born of man’s haste; the true fast is born of God’s patience. The fast that ascends to heaven is not the one seeking confirmation, but the one seeking communion. It’s not the fast of hunger; it’s the fast of longing. It’s not the fast of “do it for me,” but the fast of “speak to me.”
“Rend your heart and not your garments. Return to the Lord your God.”
(Joel 2:13)
