I was wondering about who lives where in the Millennium. To go a step further, say we go in the rapture but have a family member who gets saved during the Tribulation and survives. It is true to assume they could not visit us in the New Jerusalem, but that we could visit them on Earth? And where are the Biblical heroes and redeemed people of the Old Testament?
Believing Tribulation survivors will help re-populate the Earth in the Millennium. Those who are Jewish will live in Israel, and the others will live in the nations. They’ll still be in their natural states which means they’ll still have a sin nature. This will disqualify them from entrance into the New Jerusalem (Rev. 21:27) but we will be able to visit them on Earth. I believe that Old Testament saints will live in Israel on Earth, because only those whose names are written in the Lamb’s book of life (the Church) will live in the New Jerusalem.
