Isaiah 40:31
But those who wait for the Lord (who expect, look for, and hope in Him) will gain new strength and renew their power; they will lift up their wings (and rise up close to God) like eagles (rising toward the sun) they will walk and not grow tired.

Our confidence in the Lord and His promises gives strength to our hope. Our expectations remain stable when we have a relationship with Jesus and know, practice, and believe in those promises. We don’t get tired or weary with worry because we know God is faithful to those who believe and trust in Him.
