Performing temple ordinances for the dead anyone? I think this has a lot of insight into the next chapter of our eternal progression. Spirit paradise/prison will be a place of teaching and learning.
I think those in paradise and prison will walk and talk together and inhabit the same sphere. Prison is just a state of darkness and uncertainty. It’s a life without light and knowledge of the savior and knowledge received in the temple. Paradise being the opposite, being full of light and knowledge being able to rest in that assurance of the savior and being able to share that knowledge with those who are in darkness. It will be a state in prelude to the millennial reign of the Messiah on the earth.
How can the earth be hollow and flat!? I think the flat Bigfoot theory is more accurate. It explains why we’ve never had a head-on picture of the Bigfoot!
