-A block universe, whether we make it exist by fatalism or theology, is a universe where every moment in time exists at the same time. This is incoherent, as it asserts there is a time in addition to all time.
-Or this: if all time is known by God, it is like a film that has already been shot. But a film that has already been shot has a crucial difference to the universe known by God: the whole film is determined because it exists at one time, but the universe in the divine mind does not exist at one time, but in eternity.
-God sees all things when they happen, but not before they happen. “When” indicates unity, which can happen between ontologically distinct things (like spirit and body, meaning and sound, divine and human nature) but “before” indicates division or separation in time.
-If you see things before they happen, you either see a representation or the event itself.
A representation would not suffice for knowledge unless it came from one who saw the event itself.*
But if one sees the event itself before it happens, then he sees, say, 2025 in 2015.
But this means 2025 itself occurs in 2015, which is a contradiction.
So if one knows he sees the future, he does not see it before it happens.
*Even if some machine infallibly delivered you snapshots of things that came to happen the next day, your trust would be in the judgment that it wasn’t just hitting a lucky streak of prediction but was based on some process that had contact with the event itself.
