The book of Job does not really give an answer to why good people suffer. It begins with "Why?" and ends with "Who?" Being a person of faith, living a godly life does not ensure that you will never suffer. Being a Christian does not make us immune to suffering. Indeed, being a person of faith may well bring on additional suffering! Jesus, surely the most wonderful example of who God wants us to be, did not escape suffering. Nor did most of his disciples. Faith does not save us from suffering, and this is one of the points this story makes.
