Isaiah 40:31 promises that people who wait on the LORD receive renewed strength, so that they can rise, keep going, and not collapse under the weight of their lives. The verse describes a kind of strength that comes from trusting God, not from our own stamina, which fails sooner or later for everyone. The words were spoken by the prophet Isaiah, who wrote to the people of Judah, many of whom were discouraged, exhausted, and far from home.
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 phrase “wait for the LORD” does not describe passive sitting around. In Scripture, waiting means keeping your eyes fixed on God, expecting him to act, and refusing to rely only on yourself. Those who do this will “renew their strength,” which literally means they will swap their worn-out energy for a fresh supply that comes from God.
The imagery of mounting up on wings like eagles speaks of soaring above difficulty and seeing it from a higher place. Running without weariness and walking without fainting describe ordinary endurance: the strength to sprint when needed and the steadiness to keep plodding when the road is long. The verse does not promise that life will become easy, that you will never feel tired, or that every prayer will come out the way you hope. It promises that God will sustain his people in real strength, for the real demands they face.
The Context of Isaiah 40:31
Isaiah 40 opens a major section of the book often called “the book of comfort,” because it turns from judgment toward promises of restoration. The prophet speaks to a people who feel forgotten, asking whether God has noticed their suffering. Just before verse 31, Isaiah asks them whether they have not heard that the everlasting God never grows faint or weary, and that his understanding cannot be measured.
Verse 29 then says that God gives power to the weak, and verse 30 admits that even young and strong people become exhausted. That honest picture of human limits is what gives verse 31 its weight. The promise is not aimed at people who have it all together, but at people who have reached the end of their own resources and are ready to depend on the LORD.

A Short Prayer From Isaiah 40:31
Lord, I confess that I often try to carry my burdens on my own strength, and I grow weary when that strength runs out. Teach me to wait on you with expectant trust, lifting my eyes from my exhaustion to your faithfulness. Renew what I have spent, and give me steady feet for the road ahead, so that I can keep going in your care. Amen.
