Job 38-42: The Believer That Returns To Believe

Job has stopped to believe in God. He has given up his will and power to keep hope and faith on God. But then God shows himself and talks with Job, and reveals all that he has done in the earth. This part where Job had given up on something and suddenly starts to believe in it again reminds me of some events that sometimes happen in life. For example you are rooting for a team in a soccer match that is really losing badly. Then you give up on that team and think that the team will lose and there is nothing to do about it, so you turn your TV off. Then when you go to school or to work your friends tell you that your team won, and then you start having faith again and tell yourself that next time you will not turn the TV off. I think that Job got the same teaching from the event with God so he will never give up on God again. Then God punishes the friends that have tried to bring Job up. I did not really understand why God punished them? Or if he just punished them for not convincing him into turn him back into believing in God? In any case I thought this to be kind of unjust because His friends where the ones that were with him in the good and bad times and now they are being punished.
