"Do you not know? Have you not heard? The Lord is the everlasting God, the Creator of the ends of the earth. He will not grow tired or weary, and his understanding no one can fathom. He gives strength to the weary and increases the power of the weak. Even youths grow tired and weary, and young men stumble and fall; but those who hope in the Lord will renew their strength. They will soar on wings like eagles; they will run and not grow weary, they will walk and not be faint."
— Isaías 40:28-31
We live in an age of constant hurry. We wake up to notifications, work under pressure, and fall asleep thinking about what we didn't accomplish. Many of us reach the middle of the week already exhausted—not just physically, but emotionally and spiritually. We look at our circumstances and feel that our strength has run out, that we cannot endure even one more day. It is in this universal truth of human weariness that Isaiah brings us an extraordinary word.
The prophet does not deny our weakness. He recognizes that youths grow tired, that strong people stumble and fall. But here is the sublime secret: there exists a source of renewal that does not depend on our capacity, our willpower, or our planning. The God who created the universe, who knows every star by name, does not grow weary. His energy does not diminish. And the promise in Isaiah 40:31 is categorical: those who hope in Him will renew their strength.
Hoping in the Lord is not passive resignation; it is active trust. It is that moment when you place your struggle in God's hands and acknowledge that victory does not depend solely on your effort. It is when you step out of your own strength and enter His. Eagles do not move by their own strength when flying at altitude; they use air currents. Similarly, when we learn to hope in the Lord, we learn to move in the currents of His will and power.
Think about your life today. Where are you exhausted? What struggle do you carry alone? The divine invitation is to leave that weight at the foot of the cross. It is not weakness to seek strength in God; it is wisdom. Set aside some genuine moments of silence today. Do not speak, only listen. Let the presence of God touch those wounded and weary places in your soul. Renew your strength at the source that never runs dry.
You are not alone in this journey. The God of Isaiah, the one who sustains all creation, sustains you as well. Your strength will be renewed not because you deserved it or achieved it, but because you trusted. And this renewal comes like eagle's wings: invisible, yet real and powerful.
