The story of Job sums it up for me. God made a bet with the devil, ruined Job's life like it was a huge game, killing everyone Job knew along the way.
Job didn't revoke God, though... He DID ask why, and God was pretty upset about this, gave him a lecture and basically said:
"What happens happens and I do what I want. I'm GOD, dammit."
When bad things happen, I just assume God has made another bet with the devil and we're the collateral damage. That, at least, is what I hear from the story of Job.
If the story of Job shows how god treats one of his most faithful worshipers, I really don't stand a chance.
