The problem, of course, is that this doesn't EASILY fit with:
1. A God who has everything planned. 2. A God who knows everything.
If God had planned all along that he would add 15 years to Hezekiah's life, why tell Hezekiah "you will surely die?" It would be a lie, wouldn't it, if a person had said the same, having planned the same?
Even if God had known all along that he would add 15 years to Hezekiah's life, then the same conclusion. If a person had said the same, wouldn't we call it a lie/misrepresentation, given their prior knowledge?
Open theology says that God is open to real contingency, and that therefore, he knows perfectly all knowledge that actually exists, but he knows contingent knowledge perfectly only in knowing perfectly all the contingencies (and permutations, thereof.) But this doesn't violate God's omniscience, they say, because what doesn't exist with a true contingency is the decision on the other side.
In other words, God is "open" to the new contingency.
Now, these folks are trying to deal honestly with some puzzling scripture. Many want to tell them simply to shut up.
For me, I like the timeless God answer better than the open God answer, but I had to read the book and think about it. I don't mind that others do that, too.
Another choice of course is the asbestos underwear and green wood.
