MHG,
This is headed into an area that is not covered in scripture, and conjecture is not fact, so I am hesitant to offer mine in this forum, so as not to mislead however unintentionally.
Aside from that, John ch 3 is very convincing to me. Nicodemus was an educated priest, who understood the written scripture, and was a true believer, not a scoffer.
I believe the things Yeshua told him were for our edification too. I have never walked invisibly through a room, have you? I believe all that Yeshua said in that chapter is at/post-trumpets.

You offered what was an opinion regarding spaceless and timeless but did not characterize it as such. I merely offered to you what God’s Spirit has shown to me regarding the nature of the Universe as revealed in scriptures. I have been pondering this subject for decades. What I offered to you has taken years to coalesce to the degree that I can put it into words most do understand. Take or leave it ... your teachers are not what you believe them to be.
