“Though youths grow weary and tired, and vigorous young men stumble badly,…” (Isaiah 40:30).
The independence, strength, and confidence of youth will eventually fail. These being described by the prophet were the most select of the strongest and the fittest; the elites that would serve in military service or athletic contests. Isaiah sets this vision of youthful vitality before us to show its vulnerability on the larger stage of suffering and hardship. In this context the brightest, strongest, and most gifted among us will finally hit the wall; exhausted and beaten down by the blows life has brought against you. Once this broken state overtakes you, when the realization dawns that you can’t do this on your own, it is then you discover a new strength in the Lord.
