Isaiah 40:31
But they that wait upon the LORD shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint.
Verse Context
The Book of Isaiah was written by the prophet Isaiah, whose ministry spanned the reigns of several kings in Judah, roughly from 740 to 681 B.C. Isaiah chapter 40 marks a clear transition in the book—from judgment and warning to consolation and comfort. In fact, Isaiah 40 is often seen as the opening of the “Book of Comfort” within Isaiah (chapters 40–66), which shifts the focus from Israel’s failure to God’s promises of restoration and redemption.
This verse appears in a context where God is reminding His people of His incomparable power and everlasting nature. Isaiah 40:28–30 leads into this by highlighting the weakness of even the strongest human beings: “Even the youths shall faint and be weary, and the young men shall utterly fall.” But verse 31 offers a glorious contrast—the strength of those who wait on the LORD.
- They that wait upon the LORD – The word “wait” here is not passive; it’s a deep, trusting expectancy. It means to confidently hope in the Lord, relying on His timing and provision rather than our own effort.
- Shall renew their strength – To “renew” means to exchange. This is not just regaining strength, but trading in our weakness for His divine strength.
- Mount up with wings as eagles – The eagle was considered the strongest and highest-flying bird. To “mount up” suggests elevation above life’s chaos, just as an eagle soars above the storm. It’s a picture of spiritual power and victory.
- They shall run, and not be weary; and they shall walk, and not faint – These represent both the rapid pace of life’s urgent moments (running) and the steady endurance needed for the daily journey (walking). In both, God supplies what is needed.
Commentator Matthew Henry (1662–1714, English Nonconformist) explains it this way: “Those that hope in the Lord shall have the comfort of it; they shall be supplied with grace sufficient for them.” John Gill (1697–1771, Reformed Baptist) also notes that this waiting involves faith, prayer, and patient endurance.
Broader Context
Isaiah 40 opens with the tender words: “Comfort ye, comfort ye my people, saith your God.” The people of Judah, discouraged by warnings of judgment and exile, are now being reminded of God’s unmatched greatness and intimate care. The chapter builds on the contrast between human frailty and divine omnipotence. The point is clear: God does not grow tired or weak—He gives power to the faint (Isaiah 40:29).
The broader message is one of covenant faithfulness. Though Israel had sinned, God’s promises endure. The comfort in verse 31 is not generic motivation—it’s covenantal assurance: God strengthens those who trust in Him because He has bound Himself to His people by promise.
Isaiah 40:31 is not isolated inspiration—it is the climax of a chapter that teaches theology through poetry: God is Creator, Sustainer, King, Shepherd, and Redeemer. The encouragement here flows from His nature, not ours.
Application
Appreciating God’s Greatness
This verse magnifies God’s character. He alone can offer renewed strength to the weary because He Himself is never weary. He lifts His people from despair not by easing every burden immediately, but by infusing them with supernatural endurance.
For the Believer
Believers are often tempted to act quickly, solve everything themselves, or despair in the silence. But God says to wait—to trust, to linger in prayer, to be still while He works. The reward is not just rest but a total transformation of strength. You will fly again, not crawl. You will run, not collapse. You will walk on faithfully, not give up.
Call to Action:
If you are weary today, resist the urge to quit or to take shortcuts. Instead, renew your focus on the Lord. Spend time in His Word, pray without rushing, and ask Him to help you wait with expectancy. Strength is promised—not to those who act first, but to those who trust first.
For the Unbeliever
If you do not yet know the Lord, your strength is your own—and it will eventually fail. You may run for a while, even soar briefly—but weariness will come. Only those who trust in the Lord Jesus Christ as Savior and Redeemer can experience this supernatural renewal. You were not made to carry your burdens alone. Come to the One who gives rest to the weary and strength to the faint.
Final Encouragement
Isaiah 40:31 is more than poetry—it’s a promise. God is not distant. He is near, strong, and faithful. Whatever today holds, know that if you place your hope in Him, He will carry you through. Not with your own limited strength, but with His unlimited supply.
Prayer
Heavenly Father, thank You for the promise of renewed strength. So often we feel weary, overwhelmed, and unsure of the path ahead. But You do not grow tired, and You never abandon Your people. Help us today to wait on You—not with anxiety, but with trust. Teach us to rest in Your timing and draw on Your power. Let us mount up with wings as eagles, rise above discouragement, and walk forward with courage, knowing You go before us. In Jesus’ name, Amen.
You are loved—so much in fact, that we want you to know and be Believers of Biblical Truth.
Shalom Shalom.
