Then I saw a new heaven and a new earth, for the first heaven and the first earth had passed away, and there was no longer any sea. (Revelation 21:1)
Behold! The new world of righteousness!
Everyone who is saved shall live here; some, as members of the Church, who shall govern the new world; some as citizens who will enjoy love, joy, and peace forever through the ministry of the saints.
The Church is the new Jerusalem, the Tabernacle of God. The citizens are people who have been saved from the nations of the earth. They are the "sheep," whom Christ places at His right hand. It is for them the Kingdom of God has been prepared.
