The book of Job is set up with a conversation between God and the Devil and the next 40 chapters record the wrestling with the results of that conversation.
But it ends not with what would have been the Hollywood ending of the Devil admitting his failure but with a conversation between Job and his God.
I've got a feeling that this whole book was far more about God's eternal love for one of his servants to discover the ultimate prize in this life and the next - to be FULLY satisfied with God as his greatest treasure.
To stop eating the "crusts of rumour & hearsay" about God and discover the Him for what he is - THE BREAD OF LIFE.
Revelation removes rumours!
