I worship you, Lord, for you are the everlasting God, the Creator of the ends of the earth. You do not faint or grow weary; your understanding is unsearchable. You give power to the faint and to those who are weak, you increase their strength. Even when youths are growing faint and weary and young men falling exhausted, those who wait on you, O Lord, shall renew their strength; we shall mount up with wings like eagles; we shall run and not be weary; we shall walk and not faint (Isaiah 40:28-31).
