We can learn that humanity bases their life upon reward and retribution principle. They think that if you are good, good things will happen, but if you are bad, bad things will happen to you. The humanity is willing to accept only good things, and when bad things happen, they are ungreatful.
What we can learn about God is that He is willing to prove to Satan that Job would be faithful to Him even if Job was suffering. He was willing to “sacrifice” Job in order to prove his point. Although in the end, it turned out even better than the begining. God knew that Job would be faithful to Him. God let satan ruin job’s life, so God let’s bad things happen to good people.
What we can learn about relationships is that you never know who you’re real friends are until something bad happens. For example, we can observe Job’s wife. She saw that Job was “aflicted” and had lost everything. She said “curse God and die!” Maybe she was interested on how wealthy he was and not cause she loved him. Even if you don’t agree with someone you care about, you should never say that to them. Job clearly had a close relationship with God, because when he lost everything, he “fell to the ground in worship.”
We can learn about Job and his family that Job maintained his integrity to God which tells us he was very religious, and his children died and his wife abandoned him.
