Job 38:1-7

38:1 Then the Lord answered Job out of the whirlwind:
38:2 “Who is this who darkens counsel
with words without knowledge?
38:3 Get ready for a difficult task like a man;
I will question you
and you will inform me!
God’s questions to Job
38:4 “Where were you
when I laid the foundation of the earth?
Tell me, if you possess understanding!
38:5 Who set its measurements – if you know –
or who stretched a measuring line across it?
38:6 On what were its bases set,
or who laid its cornerstone –
38:7 when the morning stars sang in chorus,
and all the sons of God shouted for joy?

You've got to read the whole thing. It puts you in your place fast! :) It shows God awesome power and creation. Job is a good book to read.
