Revelation 21:23 tells us that New Jerusalem “has no need of the sun or of the moon that they should shine in it, for the glory of God illumined it, and its lamp is the Lamb.”

Both God and the Lamb are sitting on the throne [Rev. 22:1]. They are not sitting side by side. Rather, God is in the Lamb. God is the light and the Lamb is the lamp (Rev. 21:23). The glory of the light and the lamp are not side by side. The light is in the lamp. The Lamb as the lamp shines with God as the light. This indicates that God is in the Lamb sitting on the throne. They two are actually one, just as the light and the lamp are one unit, one entity. God in the Lamb is the redeeming God. For eternity in the New Jerusalem we shall see the redeeming God, God in the Lamb.*

In New Jerusalem there is one throne and one light because God is one! The oneness of God and the Lamb presented in the paragraph above is not something new in New Jerusalem. Rather, it is an eternal oneness.

In John 14 the Lord Jesus said, “Believe Me that I am in the Father and the Father is in Me” (v. 11). In John 10:38 He told us to believe Him so that we know and continue to know this divine fact. This fact is for us to experience and live by today (John 14:20) and it will be manifested in full by New Jerusalem.
