Isaiah 40: Why the LORD Is Your Only Hope

Introduction

It's the end of the year. You look back at the months that have gone by: the joys, the sorrows, the plans that held together and the ones that blew up mid-flight. And already, you're wondering what the new year will bring. A child who still hasn't come. A sickness that won't go away. A season of singleness longer than you expected. An unstable job. A faith that's wavering. Underneath all of it, one question keeps coming back: who, or what, am I placing my hope in?

That's exactly the state Israel was in when Isaiah spoke these words: divided, dominated, exiled. In this message preached at Momentum to close out 2025, Armel opens Isaiah 40, verses 12 to 31, and issues an invitation that reaches across the centuries: People of God, the LORD is your only hope. Two reasons back that invitation: you have thousands of reasons to worship him, and you have no reason to worry.

Message Outline

1. Israel's context: a people at the end of their hope

• The LORD had made Abraham a promise (Genesis 12): his descendants would become a blessed nation, one that would bless the whole world.
• But Israel disobeyed, rebelled, and placed its trust in the idols of neighboring nations. So God allowed foreign nations to dominate them.
• By the time Isaiah prophesies, the people are split in two: the northern kingdom, crushed by Assyria, and the southern kingdom, Judah, whose capital is Jerusalem, later to be carried off to Babylon.
• Israel is broken, weighed down by fear, in the middle of a full-blown crisis of hope. But God hasn't forgotten his people. Chapters 40 to 66 of Isaiah are the great song of comfort: God wants to console, rebuild, and lift up.
• And at the heart of this section stands a solemn invitation: People of God, the LORD is your only hope.

2. Thousands of reasons to worship the LORD (v. 12 to 26)

Armel offers an image: put on a virtual reality headset and let God walk you through his reality. He's about to show you his greatness against four rivals that all try to take his place in your heart: nature, science, nations, and idols.

Nature

• "Nature really gets it right." We've all heard that. We admire the waves, the sun, the precision of the living world. Eventually we end up worshiping creation itself.
• But who has measured the waters in the hollow of his hand? Who has weighed the mountains on a scale? Mount Everest, nearly 9 kilometers high, an object of human fascination. In God's eyes, it fits in the palm of his hand.
• Placing your hope in nature is worshiping a creature. Placing your hope in the one who made it is an entirely different kind of security.

Science

• Sending a message around the world in a second. Operating on a patient remotely. There's plenty to be amazed by in human progress.
• But who taught God how to set the exact distance between the earth and the sun, close enough for life-giving light, far enough that we don't burn?
• Where does the human intelligence that invented Facebook, Instagram, and modern medicine come from? From the Creator of all intelligence. God rules over science because he is its source.

Nations

• In Isaiah's day: Babylon, Assyria, Egypt, Rome, Lebanon and its famous cedars. Powers that seemed eternal.
• Today: China, Russia, the United States, Japan. Giants we're tempted to bet everything on.
• What's left of Rome? Ruins. Of ancient Egypt, that superpower equivalent to today's United States? Pyramids. "Fine dust that blows away."
• Psalm 2 says it plainly: the kings of the earth take their stand against God, and the one enthroned in heaven laughs at them. Placing your ultimate trust in a government is guaranteeing yourself disappointment. They're human; they pass away, whether they lean left or right.

Idols

• An idol is any human-made representation to which we attach our faith: humanity building its own god and hoping it lasts.
• Armel tells of his visit to Ayutthaya, Thailand, the former capital of the Kingdom of Siam. There he saw Luang Pho To, a monumental Buddha statue, 19 meters tall, entirely covered in gold. Nicknamed "guardian of the sailors," it was meant to protect the trading city.
• The city was destroyed more than once. The statue was broken and rebuilt. Ayutthaya lost its status, replaced by Bangkok. The "guardian" couldn't guard anything.
• "To whom will you compare God?" No craftsman has the wisdom to represent him. No material can withstand time well enough to portray him rightly. God alone keeps his word. God alone remains.

3. No reason to worry (v. 27 to 31)

• Verse 27: "Why do you say, Jacob, and speak, Israel: My way is hidden from the LORD, and the justice due me escapes the notice of my God?"
• In other words: after everything we've just seen, how could your thoughts still convince you that God has forgotten you?
• God appeals to his people's memory. He is the same God who promised Abraham. The same one who split the sea to free Israel from 400 years of slavery in Egypt. He hasn't changed.
• "The everlasting God, the LORD, the Creator of the ends of the earth, doesn't faint. He isn't weary. His understanding is unsearchable."
• No oppression, no incurable illness, no social conflict, no grief, no relational crisis lies outside his reach. A thousand years are, in his eyes, like yesterday (Psalm 90).

4. The promise: renewed like eagles

• Verse 31: "Those who wait for the LORD will renew their strength. They will mount up with wings like eagles. They will run, and not be weary. They will walk, and not faint."
• Watch for the silent condition: the promise is for those who wait for the LORD. Not for those hedging their bets fifty-fifty ("I believe in God, but I also believe in human intelligence," "I believe in God, but I also believe in nature").
• This new strength belongs to those who place their trust exclusively in the LORD.
• This hope is also active. It shows. It proclaims God as the only one worthy of worship. It touches the people around you.
• And today, this word finds its fulfillment in Jesus Christ, who died and rose again to give us new life: a life that already has implications now, and a firm hope for the new world to come.

Key Takeaways

• Your hope is only as good as what it's placed in. Nature, science, nations, idols: all of them will let you down eventually. God alone never moves.
• God doesn't need anyone to explain to him how to run the world. He has measured the waters in the hollow of his hand. Your current problem isn't too big for his palm.
• God hasn't forgotten you. His silence isn't his absence. His memory of you has never faltered.
• The promise of being renewed like an eagle isn't for those hedging fifty-fifty. It's for those who hope in him exclusively.
• In Jesus, his people's future is secure. In him, so is yours.

Personal Application

• What's the real source of my hope right now? A plan, a person, a system, a sum of money, or the LORD?
• Where am I hedging fifty-fifty with God? On what specific point am I keeping a backup exit "just in case"?
• What past promise of God's faithfulness do I need to remember in order to walk into the new year without being crushed by fear?
• In front of which "mountain" (health, finances, a relationship, a calling) do I need to remember today that God holds Everest in the palm of his hand?
• How can my hope in the LORD become active and visible to the people around me this week?

Frequently Asked Questions

Does hoping in the LORD mean accepting passivity?

No, it's the opposite. The text speaks of eagles mounting up in flight, of people running and walking without growing weary. Hope in the LORD is active: it proclaims, it testifies, it acts. It simply refuses to bet on what's going to collapse. It doesn't sink into the couch waiting for God to do everything alone.

What do I do when I've prayed for a whole year and seen nothing move?

That's exactly Israel's cry in verse 27: "my way is hidden from the LORD." God's answer isn't a new lecture, it's a reminder. Remember who he is. Remember what he has already done. His silence isn't his absence. His understanding is unsearchable: what you don't understand now, you'll understand later, or in eternity. In the meantime, he doesn't faint and he isn't weary.

Practically speaking, how do I get out of a "fifty-fifty" hope?

Start by identifying your backup exit. Where are you keeping a secondary trust in case God isn't enough: a bank account, a person, a reputation, a skill? Name it. Confess it. Ask God to become your only hope in that specific area. Then take one concrete step of obedience that puts that trust to the test. Faith always grows through movement, not through theory.
