I thought time was the glue that holds the 3 demensions together. Without time you would be able to see from the begining to the end. You could see all sides of a 3 demensional object.
The bible says that for God, one day is like a thousand years, an indication that he exists in an arena without time.
I believe our minds exist in a place where there is no time. That is why we have visions of the past, and visions of the future.
