Thank you so much for your encouragements and for sharing your insights!
I merely objected, I think, to the notion that God does not or cannot or has not chosen to manifest in a . . . . HEAVENLY CONTEXT . . . at least analogous to space, tangible space. I contend that the evidence is that He has.
I probably should have extended my remarks a bit further in discussing the Jewish mystic view of the firmament, re: post 12477 Their view that the firmament is not geometric but a boundary between the spiritual and physical realms rings true in the Spirit for me, i.e. that the physical and spiritual realms are not spatially separated.
I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me. - Gal 2:20
However, as I said, their musing that the firmament is the "speed of light" doesn't bring a leaning for me in either direction, i.e. true of false. It is equally possible that the boundary is dimensional though not spatially separated per se.
Visualize the firmament as one of the planes (colors) in this rotating hypercube (which, btw is merely 4 dimensional.)
IOW, we are able to sense four dimensions - three of space and one of time. We cannot "see" in four spatial dimensions as in the hypercube. We see in three spatial dimensions and sense time passing. But it is possible - likely even - that more spatial and/or temporal dimensions exist. An interesting side point is that sensing one additional temporal dimension would yield our timeline (arrow of time or sense of time passing) as a plane - where past, present and future all co-exist on the plane. Such a dimension would comport with prophesy as well as answer a number of anamolies in physics: non-locality, superposition, etc.
IOW, as denizens of physical reality with vision and mind limited to four dimensions (3 spatial, 1 temporal) - we would not be able to "see" the spiritual realm, but the denizens of the spiritual realm might be able to "see" us being separated by perception of one or more higher dimensions (or planes):
For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known. - I Cor 13:12
IOW, if that were the case, those mansions Christ promised would be even more "real" in terms of space/time than what we perceive as physical reality in 4 dimensions. Those are just my musings on the matter - not leanings in the Spirit. But they are every bit at reasonable and consistent with Scripture as the Jewish mystic musing that the firmament is the "speed of light."
