Where is air in time? Is there a temporalness to it? Because if we breath in air, we breath it out again. Might use a few molecules of what was in the air, but it's still air going in and out. And what we take out of it, (oxygen), is reinserted into it by plants, and what they take out of it, (carbon dioxide), we put back in, thus it is in a constant state of being. I think outside of time is something like that.
And, I think most people think there is temporalness even in heaven, because who can fully, or even partially, grasp nontemporal as temporal beings? I don't get what it looks like or will be at all, except since God always was, without ever having a beginning, then why would we not be in a similar state of being as he is? So, yeah, I do get it is an odd theory. Anything we propose is just a theory, but otherwise, how many Judgement Days will they be? As it stands now, there would have to be at least 10 billion of them to accommodate every single human being when we die.
1. Since time is non-spatial, it would seem there really is no such place as "outside of time".
As a theoretical, we can use the term "outside of time", but we really don't have any way to define it, explain it, or even suggest what it might mean... I'm not sure it means anything at all, and I'm not sure it's logically possible for such a thing to exist.
2. After God created time, it would seem that God is indeed in time, as we are.
God would be "in" time because there is no "outside of time" to reside in... time is non-spatial.
Time is the existence of temporal becoming - change and motion creating a "before" and "after"', not something that has spatial dimensions.
In the Bible, we see God using tenses of time: he talks about before and after, he speaks of things he did in the past, and things he will do in the future.
This means God is experiencing the temporal realm he created.
Just the fact that God is ACTING requires him to be acting in time... as there is no way for action to occur without time, because action itself generates a "before" and "after", and thus time.
So God would seem to be currently "in" time, but not burdened by it as we are.
- The future isn't mysterious or scary to him because he knows the future.
- He is never "out of control" as he would have all power to change the future as he sees fit.
- He doesn't age, or grow weary, or suffer any negative effects of time... he is an eternal being.
I believe all the ideas I'm explaining are both Biblically and philosophically sound,
and would be considered within orthodox theological views,
but I may be explaining them poorly.
