Have you not known? have you not heard? The everlasting God, Yahweh, the Creator of the ends of the earth, doesn’t faint, neither is weary; there is no searching of his understanding. He gives power to the faint; and to him who has no might he increases strength. Even the youths shall faint and be weary, and the young men shall utterly fall: but those who wait for Yahweh shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; they shall walk, and not faint. (Isaiah 40:28-31, WEB)
How can I be strong during difficult times? I will hope in the Lord, and He will revew my strength!
