Since most Calvinists are harshly critical of the novel The Shack (which takes a similar approach to theodicy as Greg Boyd in Is God to Blame?) because of its alleged undermining of God's glory and sovereignty, why don't they (or one of them) write a similar novel in which God explains to Mack (or someone like him) why his daughter was kidnapped, raped and murdered--and avoid language about God permitting or allowing it (which is really Arminian language)?
Quite a tall order. I would not relish the idea of explaining why God decrees the rape and murder of a little girl. And that is one of the root problems with Calvinism. If God ordains everything and he is good, then why do evil things happen?
I personally nominate Tim Challies to write the book.
If you are unfamiliar with "The Shack", you have been living in a cave. :) It is a popular and controversial Christian novel. My review is here.
