Strength for the Battle

Isaiah 40:27-31

²⁷ Why do you say, Jacob, and declare, Israel, “My way is hidden from the LORD, my God ignores my predicament”? ²⁸ Don’t you know? Haven’t you heard? The LORD is the everlasting God, the creator of the ends of the earth. He doesn’t grow tired or weary. His understanding is beyond human reach, ²⁹ giving power to the tired and reviving the exhausted. ³⁰ Youths will become tired and weary, young men will certainly stumble; ³¹ but those who hope in the LORD will renew their strength; they will fly up on wings like eagles; they will run and not be tired; they will walk and not be weary.
