Revelation 21:23: And the city had no need of the sun, neither of the moon, to shine in it: for the glory of God did lighten it, and the Lamb is the light thereof.

The city of holy Jerusalem symbolizes the glorified celestial earth.¹ When this resurrected earth is filled with a fulness of light² the city will have no need of the sun, neither of the moon, to shine in it.³ This fulness of light will exist only after the earth is redeemed, resurrected,⁴ and rolled back into the presence of God.⁵ When that occurs, the celestial earth will no longer exist in the current solar system under the influence of the existing sun, moon, and stars.⁶ During the resurrection, the glorified earth⁷ will become its own brilliant sun.⁸

The fulness of light on this celestialized earth will come from the glory of God⁹ ... and the Lamb is the light.¹⁰ In other words, the glory of the Father and the Son will be present on the resurrected earth in their fulness as the source of light.¹¹ The light of Christ¹² will emanate fully from the Father through the Son.¹³ The fulness of their celestial light and glory will proceed from their presence¹⁴ to all the worlds in the immensity of space¹⁵ that are part of the celestial kingdom.¹⁶ The immensity of this multigenerational kingdom already includes, and will yet include, celestial worlds without end.¹⁷
