Bible Story · Isaiah 40
Comfort, Comfort My People
The Story
The shift from Isaiah 39 to Isaiah 40 is one of the most dramatic pivots in all of Scripture. Chapter 39 ends with prophecy of Babylonian exile — Jerusalem will fall, its treasures will be carried away, its sons will serve in a foreign palace. Then without pause, chapter 40 opens: "Comfort, comfort my people, says your God." The repetition is not accident. "Comfort, comfort" — the doubled word in Hebrew signals urgency and tenderness at once. This is not a half-hearted assurance. This is God speaking directly to a specific grief with specific intent. A voice cries in the wilderness: Prepare the way of the Lord. Every valley shall be lifted up. Every mountain and hill made low. The uneven ground shall become level. The rough places plain. And the glory of the Lord shall be revealed, and all flesh shall see it together. Another voice: Cry out! What shall I cry? All flesh is like grass. All its beauty like the flower of the field. The grass withers, the flower fades when the breath of the Lord blows upon it. But the word of our God will stand forever. This is the landscape of exile — a world where human strength fades and human glory wilts. Yet into this landscape comes a word that does not wither. And that word is this: your God reigns. He comes with might. His arm rules for him. But also — and here the tone shifts to something unbearably tender — he feeds his flock like a shepherd. He gathers the lambs in his arms. He carries them in his bosom. He gently leads those that are with young. The prophet then leads the listener through a series of unanswerable questions. Who has measured the waters in the hollow of his hand? Who has marked off the heavens with a span? Who has weighed the mountains in scales? The implied answer to each is: no one, except God. The nations are like a drop in a bucket before him, like dust on the scales, like nothing at all. To whom then will you compare God? What image can represent him? No craftsman's work. No idol of silver or gold. He sits above the circle of the earth, and its inhabitants are like grasshoppers. He stretches out the heavens like a curtain and spreads them like a tent. Why do you say, O Jacob — why do you complain, O Israel — my way is hidden from the Lord, my right is disregarded by my God? Have you not known? Have you not heard? The Lord is the everlasting God, the Creator of the ends of the earth. He does not faint or grow weary. His understanding is unsearchable. And then the promise that has steadied believers in every generation of hardship: 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.
Background
Isaiah 40 is widely understood as the beginning of a major new section of the book (chapters 40–66), sometimes called "Deutero-Isaiah" by scholars, addressed to the generation facing or experiencing Babylonian exile. Babylon conquered Jerusalem in 586 BC and deported large portions of the population. The theological crisis was acute: had God abandoned his people? Had Babylon's gods proven stronger? Isaiah 40 directly answers this crisis. The image of a highway being prepared in the desert also echoes the Exodus — God preparing a way through the wilderness for his people again.
Truth
Isaiah 40 teaches that the antidote to spiritual exhaustion is not greater personal effort but a greater vision of God. The chapter methodically expands the reader's picture of who God is — sovereign over nations, incomparable in power, intimate as a shepherd — before arriving at the promise of renewed strength. Waiting on the Lord is not passive resignation; in Hebrew it carries the sense of expectant, active trust — the coiled energy of someone who knows help is coming. The chapter remains a foundational text for anyone whose strength has run out.
Application
In what area of your life does your strength feel like withering grass right now? Isaiah's invitation is to "wait for the Lord" — not passively giving up, but actively trusting in his character. What would it look like, concretely and practically, to choose that kind of waiting this week rather than striving in your own strength?
