Revelation 21:24: 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.

The nations and kings in Revelation 21:24 are from the twelve tribes of Israel that enter the celestial city of holy Jerusalem through one of the twelve gates bearing their family name.¹ These celestial-worthy Israelites are of two types. They include celestial-worthy people of the general assembly and separately they include exalted members of the Church of the Firstborn.²

The first group consists of baptized people that are celestial-worthy, but do not qualify for exaltation in the Church of the Firstborn.³ These unexalted Israelites are called the nations of them which are saved.⁴ Some Greek manuscripts omit the words which are saved.⁵ The omission is consistent with the doctrinal truth that this first group of Israelites are not saved in the sense that they are exalted. Salvation and exaltation are sometimes used synonymously, but not in this verse.⁶ John makes the distinction clear with reference to the second group of exalted Israelites called the kings of the earth.⁷ The kings are exalted Israelites with membership in the Church of the Firstborn,⁸ whereas the first group of nations⁹ are unexalted Israelites.¹⁰ The nations of unexalted Israelites walk in the light¹¹ of the celestial city,¹² while the kings of exalted Israelites¹³ bring their glory and honor to the city.¹⁴

Some scholars mistakenly believe that the nations of them which are saved represent Gentiles worthy of celestial glory.¹⁵ However, there will be no Gentiles in the celestial kingdom because all that repent and are baptized will be adopted into the lineage of Abraham.¹⁶

The kings of the earth ... bring their glory and honour into the celestial city based on the celestial law of consecration.¹⁷ By operation of this law, the Father and the Son share the fulness of their light and glory¹⁸ with the exalted kings and queens of Israel that enter the celestial kingdom.¹⁹ These kings and queens become the children of light in the fullest sense.²⁰ They then bring the light of their glory²¹ and intelligence²² with them into the celestial kingdom,²³ and consecrate that light and glory to the Father and the Son.²⁴ In this way, the shared glory and dominion of the Gods²⁵ from every generation increase throughout all time and eternity.²⁶

Revelation 21:25: And the gates of it shall not be shut at all by day: for there shall be no night there.

The gates of the celestial city shall not be shut at all by day,²⁷ which means the gates will always be open because there is no night.²⁸ There will be no physical night²⁹ because the light and glory of the Father and the Son will always shine in the celestial kingdom.³⁰

The constant daylight and open gates of the celestial city have several symbolic meanings, as follows: (1) the absence of physical threats against the celestial city,³¹ (2) the openness of the city to people from all nations worthy of celestial glory,³² (3) complete freedom of celestial residents to come and go³³ as a reward for their obedience,³⁴ (4) the absence of mortal weakness,³⁵ and (5) the absence of spiritual darkness³⁶ since darkness cannot exist where light already exists.³⁷

Revelation 21:26: And they shall bring the glory and honour of the nations into it.

Revelation 21:26 alludes to the ancient practice of kings honoring other great kings and their kingdoms with costly gifts.³⁸ After the earth dies and is celestialized,³⁹ the exalted kings and queens of redeemed nations⁴⁰ shall bring their gifts of glory and honor to the celestial kingdom.⁴¹ This is an expression of the celestial law of consecration, which requires the consecration of all things, including glory and honour, to the kingdom of God.⁴²

Revelation 21:24-27 forms a poetic Hebrew chiasmus with the following A-B-C / C-B-A sentence structure:⁴³

A	And the nations of them which are saved shall walk in the light of it:
B	and the kings of the earth do bring their glory and honour into it.
C	And the gates of it shall not be shut at all by day:
C	for there shall be no night there.
B	And they shall bring the glory and honour of the nations into it.
A	And there shall in no wise enter into it any thing that defileth….

The central focus of the chiasmus is found in the center of the poem designated by the letter "C" in the text. The words at the center of the chiasmus describe the constantly open gates of the celestial city by day and by night.⁴⁴ With this focus in mind, John invites all worthy people to enter the open gates of the celestial city, and not be among the wicked that will be excluded.⁴⁵
