Is there any interchange between the natural people populating earth (who lived through the trib) and the OT resurrected saints working in the temple with Jesus and the church resurrected saints in New Jerusalem? Will the natural people see and talk with the resurrected saints?
The only restriction the Bible mentions that would limit interaction between the various groups is that nothing impure can ever enter the New Jerusalem, but only those whose names are written in the Lamb’s Book of Life. (Rev. 21:27) To me that means the Church will have unrestricted access to Earth and the people living there.
