It's not a question, it's a statement. I probably should add an exclamation point: How Great is Our God! As in many other places in the Bible, Isaiah 40 gives us a glimpse into God's greatness. He is strong as iron and tender as a shepherd (10-11). Adjectives like enormous and wise fall so short when we consider His creation and counsel (12-13). Not only that, but God invests His power into us, His people (29). God is awesome!
