Actually, to further my answer, the kingdom comes here. I think we'll be able to access the spiritual and physical world, because we'll be 'like the angels'. I just think they'll both be here (new heaven/new earth). I don't fully understand that, but I can get a sense of it. So it is not that there is an earthly hope vs. a heavenly hope. It is the same hope (of both) for all.
Peace,
Tammy
