Job 38:21

Here is God's way of ironically affirming that Job did not know, since he was not around, when God set the earth's rotation in motion. His years were few compared to God's eternal nature.

Note that if God came down this hard on Job for merely questioning God's justice, how is God going to react to those who deny His existence. What sort of rebuke will atheists and evolutionists receive? The great lesson in this chapter is humility. We are finite and limited, to claim that we know more than God about the origin of the universe, right and wrong, and how things should work. is the height of arrogance, yet people are boastfully doing this every day.
