What are two important lessons that we should learn from the whole book of Job?

In the book
of Job, Satan is allowed to test Job by turning his life upside down. He loses his livestock,
home, sons, and ultimately his health. Satan is allowed to do this in order to test Job's faith
in God. Satan bets that if Job loses all of these things, Job will ultimately curse
God.

While Job does not curse God, Job does question God's decisions to
inflict pain upon him. God counters with questioning Job's right to question God and then
reveals to Job a greater plan for his life. Job's livelihood is ultimately restored, and Satan
loses his wager with God.

One major lesson is that God has control over all
things. Satan would not have been able to tempt Job into cursing God without God's permission.
Also, when Job questioned God, God questioned Job's right to question Him. God had a bigger plan
for Job's life. This demonstrates that God ultimately takes a long view of people's lives and
that all things work according to His divine purpose.

Another major lesson is
that God does not always grant prosperity on those closest to Him. While Job was prosperous in
the beginning, all of his prosperity and close people were allowed to be taken away. Job's faith
was deepened as a result of his communication with God during his trials. Even though Job's
wealth and health were restored, Job gained a greater understanding of God. The author of Job
wants the reader to look for God in all things, both good and bad.
