Some, if not most, theists assert that time exists in heaven. How can this be?
If time is at all based on physical laws (spacetime, emergence, etc.), it won't be able to exist as it does currently in heaven, as the laws of physics would presumably not exist in heaven (it brings up problems such as heat death, particle decay, etc.) Instead, another form of time must exist. This raises two problems.
First, could time even exist in any sort of other way than it does now? What about McTaggart's attack against the A-theory of time, for example? Is the way we experience time not simply a byproduct of our physical brain?
Second, how could one "transition" into this state? Many accounts of a resurrection like this (some are here in section 7, others here in sections 2 and 3) rely on the fact that some part of us remain the same (whether physical or non-physical). Since whatever this is - your brain, some non-physical soul, etc. - change with time (otherwise, it'd be like dying and returning to your state when you were just born), how can they transition into a different time? If whatever this "soul" is just appears in a new timeline, it isn't really the same thing; it is a copy. So, how could this transition between two different forms of time take place, given that the self must exist within time?
How would a theist answer these arguments? Of course, one could reject the idea that time exists in heaven. While some theists do this, others maintain that time exists in heaven. For example, the SEP, in section 5.2, talks about the "supposed tedium of immortality." In this section, the author very much assumes that time exists in heaven, and presents arguments within that framework. So, for a theist who asserts that time exists in heaven, how would these problems be addressed?
