I'm with Phillip Huggan here.
I also noticed along with "Poke" that this is a common religious discussion, but I would remark that it is not respective to Christianity. I live in a Muslim country and this a common topic debate amongst Muslims themselves. It is not really Christian. It is an attempt to explain reality for all people.
It seems a little out of reach to try to understand the relationship of time and the block universe. Should we really expect it to be simple? Is everything understandable? Could the block universe be other than you described?
Philosophy can imagine all sorts of logical things that are not based in reality. Maybe it is explainable by determinism, but does that mean that determinism is true?
Have a few questions though.
What rules govern the block universe?
What if there were multiple block universes?
