Salvation: Two

The Courtyard of the Tabernacle of the Congregation represents the domain of the Kingdom of God. The Tabernacle building, with its Holy Place and Most Holy Place, portrays the Church, the Body of Christ, the new Jerusalem, the holy city, the government of the Kingdom, the place of the Throne of God and of the Lamb.
The Church of Christ possesses the keys to the Kingdom of God: that is, the authority to govern the Kingdom. All persons who are part of the Church are part of the Kingdom of God and are kings and priests of the Kingdom.
We can study the relationship of the Church to the rest of the world in the following passages:
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. (Revelation 21:23)
The above verse is referring to the holy Jerusalem, which is known in the Scriptures as the Bride, the Lamb's Wife, the Church, the Body of Christ, the elect of God (Revelation 21:9).
The Scriptures refer also to the nations of saved people who are not part of the Church.
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. (Revelation 21:24)
