Isaiah 40 stands as one of the most hopeful chapters in Scripture. It speaks to people who feel worn down, forgotten, or unsure about the future. Written to Israel during exile, this chapter marks a turning point from judgment to comfort. It reminds God’s people that He has not abandoned them and that His power still sustains their lives.
The message found here continues to speak today. Life still brings waiting, weakness, and questions. This chapter meets those moments with truth. It points to God’s greatness, His care for His people, and the promise of renewed strength for those who trust Him.
A Message of Comfort After Suffering
The chapter opens with words meant to calm wounded hearts. God speaks directly, offering reassurance after a long season of silence. The people had endured discipline, displacement, and fear. Now they hear a different message.
Isaiah 40:1–2
Comfort, comfort my people, says your God. Speak tenderly to Jerusalem, and proclaim to her that her hard service has been completed, that her sin has been paid for, that she has received from the Lord’s hand double for all her sins.
These opening lines show that correction was not the final word. Mercy follows discipline. Comfort is not shallow encouragement. It rests on the truth that God remains faithful to His promises.
What This Comfort Reveals
- God sees suffering and responds
- Discipline does not cancel love
- Restoration remains part of God’s plan
This opening sets the tone for everything that follows.
Preparing the Way for God’s Work
A voice then calls out, urging preparation for what God is about to do. The imagery is vivid and active.
Isaiah 40:3–5
A voice of one calling: “In the wilderness prepare the way for the Lord; make straight in the desert a highway for our God. Every valley shall be raised up, every mountain and hill made low; the rough ground shall become level, the rugged places a plain. And the glory of the Lord will be revealed, and all people will see it together. For the mouth of the Lord has spoken.”
Valleys rise. Mountains fall. The picture shows obstacles removed so God’s glory can be clearly seen. In later Scripture, these words point to John the Baptist. In their original setting, they promised God’s return to His people.
Spiritual Meaning of Preparation
- Pride must be lowered
- Hopelessness must be lifted
- God’s presence reshapes lives
Renewal often begins with readiness.
The Word That Never Fades
Human weakness is then set against divine permanence. People fade. God’s word does not.
Isaiah 40:6–8
A voice says, “Cry out.” And I said, “What shall I cry?” “All people are like grass, and all their faithfulness is like the flowers of the field. The grass withers and the flowers fall, because the breath of the Lord blows on them. Surely the people are grass. The grass withers and the flowers fall, but the word of our God endures forever.”
This passage speaks plainly about human limits. Strength fades. Life passes. Yet God’s promises stand firm. Hope is anchored not in human effort but in truth that lasts.
Human Life Compared With God’s Word
| Human Life | God’s Word |
|---|---|
| Temporary | Eternal |
| Fragile | Unshakable |
| Limited | All-sufficient |
This contrast brings stability in uncertain seasons.
A Shepherd Who Rules With Care
God is revealed as both ruler and caregiver. Authority and tenderness appear side by side.
Isaiah 40:10–11
See, the Sovereign Lord comes with power, and he rules with a mighty arm. See, his reward is with him, and his recompense accompanies him. He tends his flock like a shepherd: He gathers the lambs in his arms and carries them close to his heart; he gently leads those that have young.
His strength is not harsh. His rule is not distant. He gathers the weak and guides those who struggle. This balance shows the heart of godly leadership.
Why This Image Matters
- Power does not cancel compassion
- God knows individual needs
- Gentle care builds trust
This picture offers reassurance to anyone feeling unseen.
The Unmatched Greatness of God
The focus then shifts upward. God is shown as beyond comparison.
Isaiah 40:12–14
Who has measured the waters in the hollow of his hand, or with the breadth of his hand marked off the heavens? Who has held the dust of the earth in a basket, or weighed the mountains on the scales and the hills in a balance? Who can fathom the Spirit of the Lord, or instruct the Lord as his counselor? Whom did the Lord consult to enlighten him, and who taught him the right way? Who was it that taught him knowledge, or showed him the path of understanding?
The questions have no human answer. Who measures the seas or teaches wisdom to God? No one. The passage confronts the tendency to shrink God to human scale.
Truths About God’s Greatness
- He created all things
- He needs no advisor
- His understanding has no limit
Awe grows when faith rests in this truth.
Above Nations and False Security
The chapter challenges misplaced trust. Nations rise and fall. Idols fail.
Isaiah 40:15–17
Surely the nations are like a drop in a bucket; they are regarded as dust on the scales; he weighs the islands as though they were fine dust. Lebanon is not sufficient for altar fires, nor its animals enough for burnt offerings. Before him all the nations are as nothing; they are regarded by him as worthless and less than nothing.
Isaiah 40:18–20
With whom, then, will you compare God? To what image will you liken him? As for an idol, a metalworker casts it, and a goldsmith overlays it with gold and fashions silver chains for it. A person too poor to present such an offering selects wood that will not rot; they look for a skilled worker to set up an idol that will not topple.
Human systems feel strong but fade quickly. Crafted idols depend on human hands. The contrast between Creator and creation becomes clear.
Trust Comparison
| Source of Trust | Result |
|---|---|
| Nations | Temporary power |
| Idols | Lifeless |
| God | Lasting security |
Only one foundation holds.
The Creator Who Never Grows Weary
A key truth follows. God does not grow tired or forgetful.
Isaiah 40:28
Do you not know? Have you not heard? The Lord is the everlasting God, the Creator of the ends of the earth. He will not grow tired or weary, and his understanding no one can fathom.
This verse answers quiet fears. Delay does not mean neglect. God’s strength does not run dry.
Why This Encourages Faith
- Waiting seasons test trust
- Silence can feel heavy
- God remains at work
Confidence grows when character is remembered.
Strength for Those Who Wait
The chapter closes with a promise that has carried believers for generations.
Isaiah 40:29–31
e gives strength to the weary and increases the power of the weak. Even youths grow tired and weary, and young men stumble and fall; but those who hope in the Lord will renew their strength. They will soar on wings like eagles; they will run and not grow weary, they will walk and not be faint.
Weakness is not denied. It is met with hope. Waiting is active trust, not passive stillness. Strength is renewed through dependence on God.
What Waiting Produces
- Renewed strength
- Steady endurance
- Long-lasting faith
This ending ties comfort, power, and hope together.

FAQs
What is the main message of Isaiah 40?
The main message of Isaiah 40 is comfort rooted in God’s faithfulness and power. The chapter speaks to people who have endured hardship, loss, and long seasons of waiting. God reassures His people that their suffering has not been ignored and that His purposes are moving toward restoration, not abandonment.
Isaiah 40 shifts the focus from human weakness to God’s greatness. It reminds readers that while people grow weary and circumstances change, God remains steady. His word endures, His strength does not fade, and His care reaches even the most worn-down hearts. The chapter calls believers to lift their eyes, trust God’s timing, and find hope in who He is rather than in present conditions.
Isaiah 40:1–2
“Comfort, comfort my people, says your God.
Speak tenderly to Jerusalem, and cry to her
that her warfare is ended,
that her iniquity is pardoned,
that she has received from the Lord’s hand
double for all her sins.”
These verses set the foundation for the entire chapter. They show that God’s discipline was purposeful, not permanent, and that mercy follows judgment. Isaiah 40 ultimately teaches that hope is restored when God’s people remember His character, trust His promises, and wait on Him for renewed strength.
Why does Isaiah 40 begin with words of comfort?
Isaiah 40 begins with words of comfort because God is speaking to people who have endured deep loss, discipline, and uncertainty. Israel had experienced exile and hardship, which left them feeling forgotten and worn down. The opening message assures them that suffering is not the end of the story. God addresses their pain directly and responds with compassion.
This comfort does not ignore past sin or hardship. Instead, it shows that God’s correction had a purpose and a limit. The opening words signal a shift from judgment to restoration. God speaks tenderly, reminding His people that forgiveness has been granted and that the season of hardship will not last forever.
The comfort in Isaiah 40 also reveals God’s character. He does not remain distant when His people struggle. He speaks, reassures, and restores. These opening words prepare the reader to trust the promises that follow throughout the chapter.
Isaiah 40:1
“Comfort, comfort my people, says your God.”
This verse shows that comfort comes from God Himself. It is not based on circumstances but on His faithfulness. Isaiah 40 begins with comfort because renewed hope always starts with knowing that God still speaks, still sees, and still cares.
What does it mean to prepare the way of the Lord in Isaiah 40?
To prepare the way of the Lord in Isaiah 40 means to make room for God’s presence and work by removing obstacles that block trust and obedience. The language is drawn from ancient practices where roads were cleared before a king’s arrival. Spiritually, it points to inner preparation rather than physical construction.
Isaiah 40 uses powerful imagery to show how God brings restoration. Valleys are raised, mountains are lowered, and rough places are made smooth. These images represent pride being humbled, despair being lifted, and resistance being reshaped. Preparing the way involves repentance, humility, and a willingness to receive what God is about to do.
This preparation is not about earning God’s favor. It is about readiness. When hearts are softened and expectations are aligned with God’s promises, His glory becomes visible. Isaiah 40 teaches that renewal often begins when people stop resisting and start trusting.
Isaiah 40:3–4
“A voice cries:
‘In the wilderness prepare the way of the Lord;
make straight in the desert a highway for our God.
Every valley shall be lifted up,
and every mountain and hill be made low;
the uneven ground shall become level,
and the rough places a plain.’”
These verses show that God’s work clears what blocks His presence. Preparing the way means allowing Him to reshape attitudes, expectations, and faith so that His purposes can be fulfilled.
How does Isaiah 40 describe the difference between people and God?
Isaiah 40 describes the difference between people and God by contrasting human weakness with God’s unchanging nature. People are limited by time, strength, and circumstance. God is not. Human life fades, but God’s word remains firm and reliable. This contrast helps readers place their trust in what lasts rather than what passes quickly.
The chapter does not speak this truth to discourage people. It speaks it to ground them. When life feels unstable, Isaiah 40 reminds believers that God is not affected by the same limits they face. While human strength runs out, God’s promises continue. His truth does not depend on human ability or endurance.
This comparison also explains why hope must rest in God rather than in people, systems, or personal effort. Human plans change. God’s word stands. Isaiah 40 calls readers to anchor faith in what cannot be shaken.
Isaiah 40:6–8
*“A voice says, ‘Cry!’
And I said, ‘What shall I cry?’
All flesh is grass,
and all its beauty is like the flower of the field.
The grass withers, the flower fades
What does Isaiah 40 teach about God’s power and care?
Isaiah 40 teaches that God’s power and care are not opposites. They work together. The chapter presents God as both a mighty ruler over all creation and a gentle shepherd who tends to His people. His authority is vast, yet His attention is personal. This balance corrects the idea that strength must be distant or harsh.
God’s power is shown in His ability to rule, reward, and act decisively. At the same time, His care is shown in how He gathers the weak, guides those who struggle, and watches over those who feel vulnerable. Isaiah 40 reminds readers that God’s greatness does not make Him detached. It allows Him to care fully and wisely.
This teaching brings comfort to those who feel small or overwhelmed. The same God who governs the universe also notices individual needs. His strength becomes a source of safety rather than fear.
Isaiah 40:10–11
“Behold, the Lord God comes with might,
and his arm rules for him;
behold, his reward is with him,
and his recompense before him.
He will tend his flock like a shepherd;
he will gather the lambs in his arms;
he will carry them in his bosom,
and gently lead those that are with young.”
These verses show that God’s rule is purposeful and His care is intentional. Isaiah 40 teaches that believers can trust both His power to act and His heart to care.
What does Isaiah 40 say about waiting on the Lord?
Isaiah 40 teaches that waiting on the Lord is not weakness or inactivity. It is an act of trust. Waiting means placing confidence in God’s timing, character, and promises, even when circumstances feel slow or unclear. The chapter acknowledges human exhaustion and then points to God as the source of renewed strength.
Waiting often happens in seasons of uncertainty, loss, or unanswered prayer. Isaiah 40 does not deny that weariness is real. Instead, it promises that God meets people in their weakness. Those who wait are not overlooked. They are sustained. Strength is renewed not by striving harder, but by relying on God.
This teaching reframes waiting as a spiritual posture. Trust replaces panic. Hope replaces despair. Over time, endurance grows, and faith becomes steady. Isaiah 40 shows that God gives exactly what is needed for the journey.
Isaiah 40:29–31
“He gives power to the faint,
and to him who has no might he increases strength.
Even youths shall faint and be weary,
and young men shall fall exhausted;
but they who wait for the Lord shall renew their strength;
they shall mount up with wings like eagles;
they shall run and not be weary;
they shall walk and not faint.”
These verses affirm that strength comes from God alone. Isaiah 40 teaches that waiting is not wasted time. It is the place where God restores endurance, deepens trust, and carries His people forward.
