Fasting is one of the oldest spiritual practices in Scripture. It’s also, at its core, remarkably similar to giving. Both require us to voluntarily let go of something – sometimes even something we depend on. Both expose what we trust. And both lead somewhere we wouldn’t have gone if we’d kept holding on.
That link between fasting and giving is worth exploring, especially during Lent. It’s a season when Christians traditionally remember Jesus’ 40 days in the desert by giving something up, not as punishment or performance, but as a way of loosening our grip on what we think sustains us and taking hold of the One who actually does.
In Isaiah 58, God defines true fasting in the language of generosity and justice:
Is not this the fast that I choose: to loose the bonds of wickedness, to undo the straps of the yoke, to let the oppressed go free, and to break every yoke? Is it not to share your bread with the hungry and bring the homeless poor into your house; when you see the naked, to cover him, and not to hide yourself from your own flesh?
– Isaiah 58:6-7
Through the prophet Isaiah, God draws fasting and giving so close together that it becomes difficult to tell where one ends and the other begins. The true practice of both fasting and giving is to shift our minds from a scarcity mentality and instead embrace a sacred trust and dependence on God to provide all we need so we can freely share with others.
This is the invitation of the Lenten season, no matter your tradition.
When we clear away what we normally lean on, we begin to see God more clearly. We depend on him more fully. We discover that the things we thought we couldn’t live without were never the things sustaining us. Fasting interrupts our habits of consumption. It requires us to depend on God to provide our daily bread. It’s in this release that true trust in him can begin to take root.
This is also, it turns out, the starting place for every act of biblical generosity. Not abundance. Not surplus. Trust. Scripture tells this story over and over. Someone with almost nothing is asked to give what little they have, and in the act of releasing it, they discover that God was sustaining them all along.
A last meal and a stranger’s request
The widow of Zarephath had reached the end of her food supply.
A famine had hollowed the land, and she was down to a handful of flour, a little oil, and a plan to make one final meal for herself and her son before they starved. She was gathering sticks for the fire when the prophet Elijah appeared asking for water and then boldly asking for something else.
“Do not fear; go and do as you have said. But first make me a little cake of it and bring it to me, and afterward make something for yourself and your son” (1 Kings 17:13).
First make me a little cake. Before your son. Before yourself. Give the last of what you have to a man you don’t know, on the strength of a promise you cannot verify.
The request only makes sense if God’s Word is more real than the empty jars in front of her. She decided it was. She made the cake. She gave it away, and through that act of trust, she clearly saw God’s provision.
“The jar of flour was not spent, and the jug of oil did not become empty, according to the word of the Lord that he spoke by Elijah” (1 Kings 17:16). Miraculously, the flour and oil lasted through the entire famine. Not because the widow had enough. But because she trusted God to provide even before his provision was visible.
An empty jar and an unexpected instruction
A generation later, a different widow stood before a different prophet with a different crisis and the same God.
This woman’s husband had been faithful, but he was dead, and the creditor was coming for her sons. She came to the prophet Elisha for help. His response cut straight to the heart of her fear and her sense of scarcity:
“What shall I do for you? Tell me; what have you in the house?” (2 Kings 4:2).
“Your servant has nothing in the house except a jar of oil.”
What Elisha told her to do with that jar made no practical sense. Go to your neighbors. Borrow every empty vessel you can find. Then shut your door and start pouring.
Picture the faith required to knock on doors, asking for empty jars when you have almost nothing to fill them with. Picture the moment she tipped her jar and the oil kept coming – vessel after vessel, filling containers she had gathered on nothing but a prophet’s word. The oil stopped only when she ran out of jars. God’s provision matched the scale of her obedience. The oil was enough to pay her debts, free her sons, and sustain her family. She had followed an instruction that sounded like foolishness, and it turned out to be the path to everything she needed.
A boy’s lunch and five thousand strangers
The pattern is not confined to the Old Testament, and it’s not confined to widows. We also see this link between our sacrifice and God’s provision in the life and ministry of Jesus.
In John 6, thousands have followed Jesus to a remote hillside, and there’s no food. While Philip does the math and concludes feeding the crowd will be impossible, Andrew chooses to look for what they already have. He finds a boy in the crowd with five barley loaves and two fish and brings him to Jesus – adding, almost apologetically, “but what are these for so many?” (John 6:9).
What they are is everything the boy has to give. And Jesus takes it, gives thanks, and feeds five thousand people with a child’s sack lunch. The boy is never named. We know nothing about him except that he had very little, he offered it to the Lord, and God made it unimaginably more than it was. The same pattern, again: not surplus, but trust. Not a calculated gift from abundance, but an open hand extended toward an outcome that made no sense until God stepped in to provide.
The pattern’s ultimate expression
Trace this thread far enough and it leads to a hill outside Jerusalem, where sacred trust finds its fullest and most costly expression.
A widow gave her last meal. Another widow poured out her only jar. A boy offered his lunch. And then Jesus gave something no one else could offer – himself.
Paul frames it in the language of deliberate release:
Though he was in the form of God, he did not count equality with God a thing to be grasped, but emptied himself, by taking the form of a servant, being born in the likeness of men. And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross.
– Philippians 2:6-8
He emptied himself. He did not grasp tightly to the life he’d been given. Luke 23:46 records Jesus’ final words: “Father into your hands, I commit my spirit.” The same God who multiplied flour and oil and bread chose to be poured out completely – trusting the Father to raise what had been given away. The cross is not generosity from abundance. It’s generosity from surrender.
What we discover when we let go
Both fasting and generosity surface the same question: What do I believe I cannot live without?
The widow of Zarephath would have said flour. The prophet’s widow would have said she had nothing left to offer. The boy on the hillside might not have thought his lunch mattered at all. We might say margin, comfort, control – the things we’ve built our sense of security around, so gradually we forgot they were never the foundation.
Every one of these stories reveals God’s miraculous provision in the face of scarcity. God does not always provide in the way we expect or on the timeline we prefer. But the biblical pattern is relentless in its conclusion: Those who let go of what they think they cannot live without will find God’s sustenance and provision on the other side.
This season, whether Lent is part of your tradition or simply a stretch of weeks you’d like to spend more attentively, consider what it might look like to hold your resources loosely, expectantly. Trust that the God who multiplied flour and oil and a boy’s small lunch, the God who redeemed the death of our Savior on the cross, is the same One asking for your dependence today.
What fasting teaches us about giving is not complicated. It trains us to release what we think sustains us and rely instead on God. Similarly, the spiritual practice of biblical generosity begins not when we have enough, but when we trust the One who does.
