Revelation 21:24-27

Verse 24 “And the nations of them which are saved shall walk in the light of it: and the kings of the earth do bring their glory and honour into it.”

Now we see that there is still a division between those who were the saints that reigned with Yeshua and live in New Jerusalem, and those who lived on earth during the millennium. As mentioned before, New Jerusalem is the new “sun” which lights the earth, and now its light still shines on the new earth. The nations of those who are saved (those who were righteous and did not rebel at Satan’s last roundup), will still walk in its light. There will still be nations and governments and kings, as the kings of the earth will bring their homage to God inside the city. All will be able to look upon the face of God.

Verse 25 “And the gates of it shall not be shut at all by day: for there shall be no night there.”

The gates of the city will never be shut. In ancient days, the gates of the cities (which were surrounded by walls for defense) were shut at night for protection. As there will be no night, but only day, there will be no need for the gates to be shut. Added to that is the fact that there will be no one who would cause there to be any need for them to be shut anyhow, as there will only be righteous people.

Verse 26 “And they shall bring the glory and honour of the nations into it.”

All the nations will bring their homage and gifts and worship into the city to present to God.

Verse 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.”

There will be no worry of anything evil corrupting the city, as there will not be anything evil to enter. Only those whose names have been written in the Book of Life will have entrance into the city. This is a given, as they are the only people who are left after the White Throne Judgment. I think this is mentioned because those people who think they are “good enough” need to realize that they are not going to enter into the kingdom of God without entering into it the way God has said that they can. Only those whose names are in the book of life will get in. One lie is enough to keep an unrepentant sinner out. It was already discussed in a previous passage what those who are an abomination are, and the other sins which keep one out of the kingdom of God, so that will not be revisited here.
