When Faith trembles, God Provides
Reading: Genesis 21:1-3; 22:1-14 Preacher: Kevin Kim
This Sunday we hear both the joy of Isaac’s birth (Genesis 21) and the testing of Abraham on Mount Moriah (Genesis 22). In fear and trembling, Abraham learns the truth of Jehovah Jireh—“the Lord will provide.”
For us, this points to the cross: just as God provided a ram in Isaac’s place, he has given his beloved son, Jesus, as the lamb for our salvation. In our own moments of fear or uncertainty, we too can trust the God who provides—yesterday, today, and forever.
Sermon Text
Friends, faith is not always steady.
Sometimes it dances and laughs — like Sarah holding Isaac for the very first time.
And sometimes faith trembles — like Abraham walking up Mount Moriah, his heart breaking with every step.
The story of Abraham and Isaac is one of the most loved and the most feared passages in the Bible. It’s the place where faith laughs, and it’s the place where faith trembles. And yet at its heart, it’s also the place where faith discovers something profound:
when faith trembles, God provides.
Today I want us to walk through this story together in three movements.
First — the laughter of promise fulfilled.
Second — the trembling test of faith.
And third — the paradox of grace that points us not only back to Abraham, but forward to Jesus, the Lamb of God.
And along the way, we’ll listen to Søren Kierkegaard SOH-ren KEER-keh-gard — the Danish philosopher who wrote Fear and Trembling, a whole book wrestling with today’s passage about Abraham and Isaac. He doesn’t let us avoid the hard questions. He shows us that faith isn’t simple. Faith trembles. Faith struggles. Faith is paradox. And yet — faith always discovers God’s provision.
- The Joy of Promise Fulfilled (Genesis 21:1–3)
Let’s start with joy.
Sarah, who had been barren for decades, finally conceives. Abraham is one hundred. Sarah herself is ninety. And yet, God does it. The impossible becomes possible. God’s promise finally had a future.
Listen to Sarah’s words: “God has brought me laughter, and everyone who hears about this will laugh with me.”
There’s no thunder or lightning. No angel choir. Just laughter. Just joy. Just Sarah knowing that God has kept his word.
And Isaac’s very name — “he will laugh” — captures that joy. Laughter is stitched into his identity.
This is who God is: the one who keeps his promises. The one who turns barrenness into fruitfulness. The one who turns tears into laughter.
But Scripture never lets us stay on the mountaintop for long. After Isaac grew past infancy, the story skips ahead… and suddenly we’re dropped into one of the darkest, most puzzling chapters in the Bible.
- The Test of Faith (Genesis 22:1–14)
“Some time later God tested Abraham.”
And the command comes like hammer blows:
Take your son… your only son… the son whom you love… Isaac.
Each phrase cuts deeper. It’s almost too much to take in.
And Abraham’s response? Silence.
Back in Genesis 18, Abraham argued with God about Sodom. In Genesis 15, he asked blunt questions about God’s promises. But here? Nothing. No protest. No bargaining. Just silence.
And maybe that’s why the story unsettles us so much. We want Abraham to argue. We want him to say, “Lord, not my boy!” But he doesn’t. He just walks.
Father and son climb the mountain. Isaac carries the wood. Abraham carries the fire and the knife.
Then Isaac speaks: “Father, the fire and the wood are here… but where is the lamb?”
And Abraham answers with trembling trust: “God himself will provide.”
Do you hear it? Those words are not light. They are not easy. They’re spoken through trembling lips. And yet, they are words of faith.
At the very last moment, as the knife is raised, the angel calls out: “Do not lay a hand on the boy. Now I know that you fear God.” And Abraham looks up — and there in the thicket (THIK-it) is a ram. He names the place Jehovah Jireh (JAI-ruh) — “the Lord will provide.”
When faith trembles, God provides.
- The Tensions We Must Face
But let’s be honest. This story still troubles us.
What kind of God asks for a child’s life?
What kind of father agrees to it?
Some say, “Don’t worry — Hebrews 11 says Abraham believed God could raise Isaac from the dead.” Maybe.
Others argue this story reflects a time when child sacrifice was practiced — and God used it to teach his people: “Not anymore. From now on, I will provide the lamb.”
And some, like J. Richard Middleton, suggest maybe Abraham failed. Maybe the test was whether Abraham would protest injustice, as he once did for Sodom. But this time, he stayed silent.
The truth is — this story does not give us easy answers. It leaves us shaking.
And maybe that’s the point. Faith isn’t about fixing every tension. Faith is about trusting God — even when the ground shakes under our feet.
- Abraham in God’s Saving Plan
Step back with me. Abraham isn’t just any character. His story is the foundation of God’s saving plan.
In Genesis 12, God calls him to leave his homeland and step into the unknown.
In Genesis 15 and 17, God promises descendants as numerous as the stars, and land as inheritance.
In Genesis 22, Abraham’s faith is tested.
And in Genesis 25, Abraham dies at 175, buried beside Sarah, leaving behind the promise.
His story is not just personal. It’s part of God’s big rescue plan. Abraham’s faith matters because through him, God’s blessing will reach the nations.
And that’s why this test matters so much. It isn’t a cruel game. It’s God discerning whether Abraham is truly the one through whom the promise can flow forward.
- Kierkegaard’s Fear and Trembling
Now let’s listen to Kierkegaard.
In 1843, he wrote Fear and Trembling under the name Johannes de Silentio — John of Silence. Because Abraham’s faith, he said, can’t really be explained. It belongs to silence.
And he makes a bold claim:
From an ethical perspective, Abraham is a murderer.
From a faith perspective, he is the father of faith.
Faith, Kierkegaard KEER-keh-gard says, is not about logic. It’s not about morality. It’s about trusting God right at the edge where nothing makes sense.
He talks about two types of people:
The Knight of Infinite Resignation — someone who gives everything up and only hopes to get it back in eternity.
And the Knight of Faith — someone who gives everything up and yet believes that God will give it back even here and now.
That’s Abraham. He gave up Isaac, yet still believed he would somehow receive him back.
And this is why the title matters: Fear and Trembling. Abraham didn’t walk up Moriah with calm assurance. He walked trembling. And only at the edge of the knife did God’s provision appear.
Jehovah Jireh is not a slogan. It’s the discovery that God provides when all hope seems lost.
- Abraham and Isaac – God and Jesus
And as Christians, we can’t hear this story without thinking of Calvary.
Abraham took his son, his only son, whom he loved.
God took his Son, his only Son, whom he loved.
Isaac carried the wood. Jesus carried the cross.
Isaac asked, “Where is the lamb?” And John the Baptist answered: “Behold, the Lamb of God.”
But here’s the difference: On Moriah, God stopped Abraham’s hand. On Calvary, God did not stop his own.
Jesus became the Lamb.
Paul says it this way in Romans 8:32: “He who did not spare his own Son, but gave him up for us all — how will he not also graciously give us all things?”
Jehovah Jireh. The Lord provides. And he has provided in Jesus — once and for all.
- Living the Triple Call of Grace (with Pilgrim’s Progress and George Müller)
So what does this mean for us?
I believe Genesis 22 calls us to live the triple call of grace.
Trust God’s promise. Like Sarah who laughed, like Abraham who obeyed, like Isaac who trusted his father.
Wrestle with God’s commands. Faith is not blind. It asks questions. It trembles. That’s okay.
Rejoice in God’s provision. At the end of the trembling, God provides. A ram on Moriah. A Lamb on Calvary. Daily grace in our lives.
And two witnesses from history remind us what this looks like.
First, John Bunyan’s (BUN-yun) Pilgrim’s Progress. It’s the story of Christian, who leaves the City of Destruction and journeys toward the Celestial (səˈlɛs.tʃəl) City. He trembles often, but every time, God provides.
At the start he falls into the Slough (SLOO) of Despond — a swamp of guilt and despair. Just when he’s sinking, a man named Help pulls him out. Jehovah Jireh — the Lord provides.
On the Hill of Difficulty, exhausted and ready to give up, he finds a shaded arbor — a resting place God has prepared along the way.
Later, trapped in Doubting Castle by Giant Despair, Christian nearly loses all hope. But he suddenly remembers the Key of Promise hidden in his pocket. He uses it and the dungeon doors swing open. Jehovah Jireh — the Lord had already provided the way of escape.
And at the River of Death, when Christian trembles most, God provides again: his companion Hopeful walks with him, reminding him of God’s promises until they reach the Celestial City.
Over and over the lesson is the same: Christian trembles, but the Lord provides. Jehovah Jireh — always enough, always on time.
And George Müller knew this truth well. Müller read Pilgrim’s Progress more than a hundred times. He drew strength from Bunyan’s pilgrim journey, and he lived it out in Bristol, running orphanages by faith alone.
Müller never asked for money. He never fundraised. He simply prayed. And God provided. Bread when the cupboards were empty. Milk when the children had none. Time after time, provision came at the point of trembling.
Through his life, the church saw again that Jehovah Jireh is not just Abraham’s story, not just Bunyan’s journey, but a living reality for us today.
Conclusion
Faith laughs and faith trembles. It holds joy and fear together. It walks roads where the promise looks threatened, and yet God provides.
Abraham shows us that faith is sometimes silent, sometimes joyful, but always trusting. Kierkegaard shows us that faith trembles at the edge where nothing makes sense.
Bunyan shows us the pilgrim’s journey — trembling in valleys, yet always finding provision. Müller shows us what it looks like today — orphans fed, prayers answered, cupboards filled.
And Jesus shows us God’s ultimate provision. On Moriah a ram. On Calvary the Lamb of God. God did not spare his own Son but gave him for us all.
So whatever your Mount Moriah is right now — whatever burden you’re carrying, whatever test you’re facing, whatever hill you’re climbing — remember this: when faith trembles, God provides.
He provided for Abraham.
He provided for Sarah.
He provided for Bunyan’s pilgrim.
He provided for Müller’s orphans.
He has provided for the world in Jesus.
And he will provide for you.
Jehovah Jireh. The Lord will provide. Yesterday, today, and forever.
