With respect, I think it stems from a human understanding of time and space.
Both time and space are creatures (or aspects of creation); neither exists apart from God. Furthermore, time and space are really the same thing: ways of expressing or experiencing the variability within creation. We humans can only experience one particular place-time. In order to get to a different place-time, we have to travel there.
For God, all places, all times are eternally present. For us, only "this particular place" and "this particular moment" are "here and now". For God, ALL places, ALL times are "here and now". We must wait for things to happen. For God, they simply exist.
Frankly, human language is inadequate to express the "God's Eye" view.
Well put. What we can and do know, we do get from His word.
