"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
How many times have you woken today already feeling the weight of the day? Perhaps it's the work that never ends, relationships that drain you, or simply that exhaustion that seems to have no clear source. It's on these gray mornings that many of us forget a revolutionary truth: our weakness is precisely the place where God finds the opportunity to strengthen us.
The prophet Isaiah was speaking to a people in exile, tired, disillusioned. They had lost everything they knew: their land, their temple, their security. It was a weariness not merely physical, but spiritual and emotional. Exactly as many of us feel at certain moments in life. But the message Isaiah brings is disturbing in its simplicity: the God who created the ends of the earth does not grow weary. He does not grow weak. While we mortals have limits, He is infinite.
But there is something deeper in this passage that we frequently overlook. Isaiah does not promise that you will not be tired. He does not offer a life without fatigue. What he promises is something far better: the capacity for renewal. Those who hope in the Lord will renew their strength. This word renewal means complete restoration, a return to original vitality. It's not a patch; it's a transformation. It's the difference between someone who simply rests and someone who returns with new energy, with a different perspective, with renewed strength.
The practical application is challenging because it requires something counterintuitive: surrender. When we are tired, we struggle to find more strength within ourselves. But Scripture suggests exactly the opposite. It is in hope, in trust, in resting in God that we experience true renewal. This means prayer when we want only to work. It means silence when anxiety wants to speak. It means letting go when everything in us wants to control. And in this act of conscious waiting, of active surrender, God works the impossible in our lives.
