Wings like eagles
Those who wait for the LORD
Start with the honest part, because Isaiah does. Even the young grow weary. Even the strong and the chosen stumble and fall flat. There is no age, no fitness, no reserve of grit that does not eventually run dry, and the rebuilt life is tiring work; anyone who has lived it knows the day the willpower simply gives out. Then the prophet turns the whole thing over. 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, walk and not faint. Watch the eagle in that line. It does not claw its way upward by frantic flapping until its wings burn out. It finds a rising column of warm air, a current it did not make and cannot manufacture, spreads its wings, and is carried up. The strength is renewed, not summoned. Received in the waiting, not squeezed out by trying harder. And Paul names the same hidden mechanism running beneath the visible wear: though the outer self is wasting away, the inner self is being renewed day by day. Reorientation never asks you to be tireless. It only shows you where the second wind actually comes from.
“Those who wait for the LORD will renew their strength. They will mount up with wings like eagles.”
— Isaiah — Isaiah 40:31 (WEB)
“though our outward man is decaying, yet our inward man is renewed day by day.”
Reorientation does not run on grit. Isaiah admits even the young collapse, then points past willpower entirely: those who wait for the LORD renew their strength. This phase teaches endurance as something received in waiting, not summoned by effort, the inner self renewed even as the outer flags. The new bearings are sustained by dependence, not by the exhausting attempt to be tireless.
The rebuilt life is exhausting, and somewhere along the way you may have run face-first into the wall where willpower stops working. Good. That wall is where the real lesson begins. Isaiah does not tell you to grit your teeth and dig deeper, as though the answer to depletion were more effort. He tells you the strength is renewed by waiting on the LORD. The eagle does not claw its way upward by frantic flapping; it opens its wings to a current already there and is carried.
You are not the source of your own endurance, and the moment you stop pretending to be is the moment a different strength becomes available, one that is given rather than manufactured. Hear this plainly: you are not asked to be tireless. The standard was never inexhaustibility. Paul saw the same thing from the inside, that even as the outer self visibly frays, the inner self is being renewed day after day after day. So when the willpower runs out, do not despair and do not push harder. Wait on God. Spread your wings. Let yourself be carried on strength you did not have to make.
The whole Church is tempted to run on sheer effort, burning its people down to stumbling youths, mistaking frantic activity for faithfulness. Isaiah points the entire Body elsewhere, to a strength renewed by waiting on the LORD. The present shaking has emptied many of the reserves Western and global Christianity used to draw on, the cultural momentum and assumed influence, and that exhaustion is not the end of the story. Across history the movements that endured were sustained by prayer and dependence rather than perpetual motion, finding a renewable power as the merely busy collapsed. Before a watching world, a Body worn thin on the outside is renewed within, mounting up on a current it did not have to generate, the source that never runs dry.
Willpower empties and the strongest stumble, but the source the waiting soul taps into never runs dry. What cannot be shaken is the LORD who renews strength in those who wait on Him, an endurance that does not depend on your reserves because it was never drawn from them. The current that lifts the eagle blows whether you are strong that day or not.
- Where have I been trying to grit my way through something that God meant me to wait on Him for?
- What does waiting on the LORD actually look like in the part of my life where I am most depleted right now?
- Have I quietly believed I am supposed to be tireless, and what would change if I let that go?
Lord, my willpower has run dry, and I have been trying to climb on wings that are already burning out. Forgive me for treating endurance as something I must manufacture. Teach me to wait on You and be carried, to receive the strength I cannot summon. Renew my inner self day by day, even as the outer self wears thin. Amen.
