Do you not know? Have you not heard? Yahweh is the everlasting God, the Creator of the whole earth. He never grows faint or weary; there is no limit to His understanding. He gives strength to the weary and strengthens the powerless. Youths may faint and grow weary, and young men stumble and fall, but those who trust 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 faint. Isaiah 40:28-31 HCSB
