Isaiah 40:31 promises that people who wait on the LORD will receive fresh strength, so that they can rise, keep going and not give out. The verse is not a promise of easy days, but a description of where lasting energy comes from. The prophet Isaiah wrote it to the people of Judah, who were facing exile and discouragement, reminding them that the God who made the earth does not grow tired.
But 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.

What Isaiah 40:31 Means
The verse begins with “those who wait for the LORD.” To wait here means to look to God, trust Him and depend on Him instead of relying only on your own resources. The waiting is active rather than passive. It is the posture of someone who keeps turning toward God while the situation remains unresolved.
Next comes the promise that they “will renew their strength.” The renewal is not described as a one-time boost but as something God keeps supplying. Then the verse uses three pictures of movement: flying like eagles, running without weariness, and walking without fainting. Each image describes a different level of effort, from soaring above a difficulty to pushing through a long, ordinary stretch of days. The verse does not promise that every hard thing will vanish. It promises that God will keep you able to continue.
The Context of Isaiah 40:31
Isaiah 40 opens a major section of the book often called the “Book of Comfort,” which speaks to Judah after the threat of Babylonian exile has become real. The book is traditionally attributed to the prophet Isaiah, who ministered in Jerusalem in the eighth century BC, though many scholars also see later voices shaping the text. Its first audience was a people who felt exhausted, forgotten and far from home.
The verses just before Isaiah 40:31 make the point clear. Verse 28 says the everlasting God “doesn’t faint” and “isn’t weary,” and verse 29 says He “gives power to the weak.” Verse 30 then admits that even young and strong people grow tired and fall. Isaiah 40:31 answers that weakness by pointing away from human stamina and toward the unchanging strength of God. That shift is what gives the verse its weight.
Key Phrases in Isaiah 40:31
Psalm 46:1
God is our refuge and strength, a very present help in trouble.
(WEB)
This verse presents God as a refuge and strength who is present in trouble. It pairs well with Isaiah 40:31 because both passages anchor hope in God’s own character rather than in the believer’s ability to cope.
Philippians 4:13
I can do all things through Christ, who strengthens me.
(WEB)
Paul writes this verse from prison, showing that strength for hard circumstances comes through Christ. Read alongside Isaiah 40:31, it reminds you that the power to endure is found in relationship with God, not self-reliance.
A Short Prayer From Isaiah 40:31
Lord, I confess that I am tired, and some days I try to carry everything on my own strength. Help me to turn toward You instead of pushing harder. Teach me what it means to wait on You with trust, and renew my strength in the places where I am running low. Let me rise when I need courage, keep running when I need perseverance, and keep walking when I need only faithfulness. Thank You that You do not grow weary, and that You give power to those who depend on You. Amen.
