Isaiah 40:28-31 teaches that the God who created the whole earth never grows faint or tired, and that he gives real strength to people who feel weak and worn out. The passage promises that those who place their hope in the LORD will be renewed, moving from exhaustion toward steady endurance. It appears in the second major section of the book of Isaiah, a message of comfort written to a people who felt forgotten.
28 Haven’t you known? Haven’t you heard? The everlasting God, the LORD, The Creator of the ends of the earth, doesn’t faint. He isn’t weary. His understanding is unsearchable. 29 He gives power to the weak. He increases the strength of him who has no might. 30 Even the youths faint and get weary, and the young men utterly fall; 31 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.

Isaiah 40:28-31 Summary
The passage moves in a clear line. It opens with a question that assumes an answer: the people have heard who God is, so why do they act as if he has lost track of them? The prophet then describes God as everlasting, the Creator of the ends of the earth, whose power and understanding never run out. Because of that, God is not drained by the work of holding the world together, and he is able to give strength to others.
From that foundation the passage turns to human experience. Even young and vigorous people eventually faint and fall, which shows the limits of human strength. The final promise is that those who wait for the LORD will have their strength renewed, described with images of eagles rising, running without weariness, and walking without fainting. The movement goes from the greatness of God to the weakness of people and then to the renewal God gives.
Context of Isaiah 40:28-31
The book of Isaiah is traditionally attributed to the prophet Isaiah, who ministered in Jerusalem in the eighth century BC, though many scholars see later hands shaping the text, especially in chapters 40 through 66. Chapter 40 opens a new section that speaks comfort to Jerusalem and Judah, a people facing exile and the loss of their land and temple. The question of whether God had abandoned them ran deep, and this chapter answers it with a call to see God’s greatness in creation.
The verses just before Isaiah 40:28 ask the reader to lift their eyes to the heavens and notice that God calls every star by name and not one is missing. The complaint in verse 27, that God’s way is hidden and justice is ignored, sets the stage for the answer in verses 28-31. The surrounding passage links God’s attention to the cosmos with his attention to a discouraged people, which gives the promise its weight.

A Prayer Based on Isaiah 40:28-31
Lord, you are the everlasting God who never grows tired, and I come to you today feeling worn down. You know the weight I am carrying, the decisions I cannot make, and the strength I wish I still had. Remind me that your understanding has no limit and your power has no end. Give strength to me where I am weak, and help me to wait for you with trust rather than to rely on my own effort alone. Renew me so that I can keep going in the places you have placed me. Amen.
