Now that God has started, He continues with more questions. It's like He has already said, "You know everything, so here's some more easy stuff!"
Job is (like we would be) probably squirming. Thinking to himself "what did I do, raising questions about God?" After all Job's words of protestation about his righteousness and goodness, and his questioning why God would do this. Job might expect some answers, but instead, God has questions and more questions.
Poor Job. Almost ready to yell out "Okay! I get it!"
But God, as God, wants to make sure that Job and his friends do not miss the point. "I Am God and there is no one like Me!" God wants to emphasize in every area of their and our understanding that we control nothing. We may think we are great, but what we are and what we control is nothing compared to "I Am".
"Listen Job, can you make a horse, and put a mane on it? How do you make it to leap like a giant grasshopper?"
It wasn't enough that God questioned Job about horses, He moves to the hawk and eagle. But the real insight comes when, just as about the weather, God asks "Do you command the eagle to build it's nest high up on a cliff?" The question is out there, and although asked of Job, I am sure his friends were a little afraid that God might ask them something. After all, they had poked their wisdom out at Job and for everyone to hear and see.
The real question is how we are feeling about a God who controls only what we could imagine. After our lambasting God, how would we answer His questions?
After all, we said we "knew."
But do we really?
