In Isaiah 40:28-31, we are reminded of the vast difference between human strength and God’s inexhaustible power. The prophet Isaiah writes:

Isaiah 40:28-31 (NIV):

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.

Our human effort, no matter how determined or energetic, is ultimately limited and exhaustible. We grow tired, we get weary, and sometimes we simply cannot continue on our own strength. This is true in many areas of life:

In our careers, we often push ourselves to the brink, believing that success depends entirely on our effort. We stay late at the office, take on more responsibilities than we can handle, and neglect rest. This relentless pursuit can lead to burnout, where our physical and mental reserves are utterly depleted.

In relationships, we might try to be everything for everyone—supportive friend, perfect spouse, attentive parent. We give and give until there’s nothing left, and then wonder why we feel empty and exhausted.

Even in our spiritual lives, we might strive to earn God’s favor through our own efforts. We attend every church event, volunteer for every committee, and try to live up to a standard of perfection that leaves us feeling inadequate and spiritually drained.

In contrast, God’s power and resources are inexhaustible. He never grows tired or weary, and His understanding is beyond our comprehension. When we rely on our own strength, we inevitably fall short. But when we place our hope in the Lord, He renews our strength.

Think about a time when you were at your wit’s end, feeling like you had nothing left to give. Maybe it was during a particularly stressful period at work, a crisis in your family, or a moment of deep personal struggle. Now imagine facing that situation with the assurance that you have access to God’s infinite power and wisdom. How different might that experience have been?

Those who hope in the Lord will find their strength renewed. They will soar on wings like eagles, run and not grow weary, walk and not be faint. This is not a promise of an easy life without challenges, but a guarantee that God’s strength will sustain us through whatever we face.

By looking to God rather than relying solely on ourselves or others, we tap into a source of strength that is limitless. We short-change ourselves when we fail to do this, settling for our own finite resources instead of embracing the infinite power available to us through faith.

Reflection Questions:

• In what areas of your life are you relying too heavily on your own strength?
• How can you shift your focus from your own efforts to trusting in God’s inexhaustible power?
• Can you think of a specific situation where you need to hope in the Lord to renew your strength?
