He giveth power to the faint; and to them that have no might he increaseth strength. Even the youths shall faint and be weary, and the young men shall utterly fall: But they that wait upon the Lord shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint. (Isaiah 40:29-31)
The Hebrew word for power here signifies physical strength and the ability to endure and overcome challenges, force, and ability. Also, the word increased in Hebrew means enlarged. God has a plan to make your strength greater than ever.
Isaiah acknowledged that even the strongest among us—youths and young men—will experience fatigue and weariness. In our world today, many people, both young and old, find themselves overwhelmed and exhausted. The pressures of the responsibilities, the tasks that need to be done, or even the callings in our lives can deplete us. Daily life can lead to physical, emotional, and spiritual fatigue. This Scripture is particularly relevant for anyone who has ever felt like they are running on empty. It’s a reminder that God wants to strengthen us. But there is a qualification in the verse. This isn’t a promise to everyone. Isaiah wrote that this promise applied to those who would wait on the Lord.
It reminds us that we are not meant to rely solely on our own strength. Instead, when we wait on the Lord—acknowledging His presence, Word, and direction—we can tap into His strength to revitalize us during trials.
Practical Application
Make it a habit to wait on the Lord throughout the day. This doesn’t mean stopping everything and sitting in silence. It means you acknowledge Him in the moment, lean on Him when making decisions, and trust in His strength to pull you through. Waiting on the Lord will recharge you spiritually, mentally, and physically. Take the time to wait.
