Isaiah 40:28-31

Don’t you know? Haven’t you been listening? YAHWEH is the one and only everlasting God, the Creator of all you can see and imagine! He never gets weary or worn out. His intelligence is unlimited; he is never puzzled over what to do! He empowers the feeble and infuses the powerless with increasing strength. Even young people faint and get exhausted; athletic ones may stumble and fall. But those who entwine their hearts with YAHWEH will experience divine strength. They will rise up on soaring wings and fly like eagles, run their races without growing weary, and walk through life without giving up.
