Revelation 21:27

27  And there shall in no wise enter into it any thing that defileth, neither whatsoever worketh abomination, or maketh a lie: but they which are written in the Lamb’s book of life.

Only those written in the Lamb’s book of life will be allowed to enter the gates to the Holy City. Those in the Lake of Fire will never have access to the Holy City. If those in the Lamb’s book of life enter the Holy City, it implies that some also go out the gates and leave, so not all in the new creation dwell in the Holy City. If all that have eternal life dwelled in the Holy City there would be no need for these passages about gates to be written at all. It seems to me that most in the Lamb’s book of life are living on the earth (or possibly elsewhere in the universe see chapter 22). However, they will be allowed to enter the Holy City.  Why even have a new earth if no one saved is living on it?  The notion most Christians hold that all people will be living in either heaven or hell in eternity makes no common sense from the scriptures.
