Isaiah 40 announces comfort, unmasks human frailty, magnifies the incomparable God, and calls weary people to renewed strength under his word.

Read more

Isaiah 40 is not gentle comfort for people who want to remain impressed with man and only slightly encouraged about God. The chapter begins in Isaiah 40:1-5 with the command to comfort God’s people, but that comfort is tied immediately to the coming revelation of the glory of the Lord. Then Isaiah 40:6-8 cuts through human self-importance: all flesh is grass, its beauty fades, but the word of our God stands forever. That means consolation is not built on human resilience. It is built on divine permanence. The chapter keeps pressing upward. In Isaiah 40:21-26, the Lord is set above nations, rulers, and stars, incomparable in majesty and unsearchable in power. Only then does the promise of Isaiah 40:28-31 land with its proper force. The weary are not being told to gather strength from themselves. They are being called to wait on the everlasting God who does not faint. Isaiah 40 matters because it asks whether you want comfort without surrendering your small view of God, and whether you can receive strength only by admitting how exhausted and creaturely you really are.

How the chapter unfolds

The chapter moves from the cry of comfort and the way of the Lord into the fading of flesh, the greatness of God, and the promise of strength for the faint.

Why this chapter matters

It matters because it teaches that comfort becomes real only when God is seen as incomparable and his word as unfailing.

Interpretive tension to watch

Do not turn Isaiah 40 into soft encouragement detached from theology. Its comfort is built on the weight of God’s majesty over every rival.

Questions for this chapter

  • Why does Isaiah 40 root comfort in the revelation of God’s greatness rather than in changed circumstances first?
  • How does the contrast between fading flesh and enduring word confront human self-importance?
  • What does the promise of renewed strength reveal about waiting on God instead of trying to outlast exhaustion alone?

1 “Comfort, comfort My people,” says your God. 2 “Speak tenderly to Jerusalem, and proclaim to her that her forced labor has been completed; her iniquity has been pardoned. For she has received from the hand of the LORD double for all her sins.” 3 A voice of one calling: “Prepare the way for the LORD in the wilderness; make a straight highway for our God in the desert. 4 Every valley shall be lifted up, and every mountain and hill made low; the uneven ground will become smooth, and the rugged land a plain. 5 And the glory of the LORD will be revealed, and all humanity together will see it. For the mouth of the LORD has spoken.” 6 A voice says, “Cry out!” And I asked, “What should I cry out?” “All flesh is like grass, and all its glory like the flowers of the field. 7 The grass withers and the flowers fall when the breath of the LORD blows on them; indeed, the people are grass. 8 The grass withers and the flowers fall, but the word of our God stands forever.” 9 Go up on a high mountain, O Zion, herald of good news. Raise your voice loudly, O Jerusalem, herald of good news. Lift it up, do not be afraid! Say to the cities of Judah, “Here is your God!” 10 Behold, the Lord GOD comes with might, and His arm establishes His rule. His reward is with Him, and His recompense accompanies Him. 11 He tends His flock like a shepherd; He gathers the lambs in His arms and carries them close to His heart. He gently leads the nursing ewes. 12 Who has measured the waters in the hollow of his hand, or marked off the heavens with the span of his hand? Who has held the dust of the earth in a basket, or weighed the mountains on a scale and the hills with a balance? 13 Who has directed the Spirit of the LORD, or informed Him as His counselor? 14 Whom did He consult to enlighten Him, and who taught Him the paths of justice? Who imparted knowledge to Him and showed Him the way of understanding? 15 Surely the nations are like a drop in a bucket; they are considered a speck of dust on the scales; He lifts up the islands like fine dust. 16 Lebanon is not sufficient for fuel, nor its animals enough for a burnt offering. 17 All the nations are as nothing before Him; He regards them as nothingness and emptiness. 18 To whom will you liken God? To what image will you compare Him? 19 To an idol that a craftsman casts and a metalworker overlays with gold and fits with silver chains? 20 To one bereft of an offering who chooses wood that will not rot, who seeks a skilled craftsman to set up an idol that will not topple? 21 Do you not know? Have you not heard? Has it not been declared to you from the beginning? Have you not understood since the foundation of the earth? 22 He sits enthroned above the circle of the earth; its dwellers are like grasshoppers. He stretches out the heavens like a curtain, and spreads them out like a tent to dwell in. 23 He brings the princes to nothing and makes the rulers of the earth meaningless. 24 No sooner are they planted, no sooner are they sown, no sooner have their stems taken root in the ground, than He blows on them and they wither, and a whirlwind sweeps them away like stubble. 25 “To whom will you liken Me, or who is My equal?” asks the Holy One. 26 Lift up your eyes on high: Who created all these? He leads forth the starry host by number; He calls each one by name. Because of His great power and mighty strength, not one of them is missing. 27 Why do you say, O Jacob, and why do you assert, O Israel, “My way is hidden from the LORD, and my claim is ignored by my God”? 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; His understanding is beyond searching out. 29 He gives power to the faint and increases the strength of the weak. 30 Even youths grow tired and weary, and young men stumble and fall. 31 But those who wait upon the LORD will renew their strength; they will mount up with wings like eagles; they will run and not grow weary, they will walk and not faint.

Comfort begins where flesh is cut down and God’s word stands above it

The chapter does not comfort by flattering human durability. It comforts by announcing that all flesh fades while God’s word remains unshaken.

Isaiah 40:31 · Hebrew Jump to text

qavah (qavah)

Literal: wait with expectancy

The term is stronger than passive delay. It suggests tension, expectancy, and dependence stretched toward God.

It makes the promise of renewed strength a call to Godward reliance rather than spiritualized inactivity.

It makes Isaiah 40 sound like theological comfort built on divine majesty rather than vague reassurance.
