Do Not Faint

Isaiah 40:27-31 Why do you say, O Jacob, and speak, O Israel, “My way is hidden from the LORD, and my right is disregarded by my God”? 28- Have you not known? Have you not heard? The LORD is the everlasting God, the Creator of the ends of the earth. He does not faint or grow weary; his understanding is unsearchable. 29- He gives power to the faint, and to him who has no might he increases strength. 30- Even youths shall faint and be weary, and young men shall fall exhausted; 31- but they who wait for the LORD shall renew their strength; they shall mount up with wings like eagles; they shall run and not be weary; they shall walk and not faint.
