Rev. 21:1 And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea. [we still have a sea, so it hasn't happend yet!]
:2 And I John saw the holy city, new Jerusalem... [If you're not willing to be a Jew, there is no place for you in heaven or the new earth. It's name is Jerusalem, not Rome.] " come out of her my people"
