Is the New Jerusalem found on earth, and will we see the Father there?
The New Jerusalem is described beginning in Revelation 21:
This scene from Revelation 21 takes place after the end of the 1,000-year Kingdom on earth. At the end of chapter 20, we’re told that our present creation will be completely destroyed and will be found no more.
In its place, the Lord will make a new heavens and earth. This new creation described in Revelation 21 completely replaces the original earth and universe. Notice in v.1 we’re told that the original earth and heavens (i.e., the universe) have passed away. In its place, a new creation called the “new Jerusalem” descends out of God’s dwelling place in Heaven. This is an entirely new creation to replace our existing one.
Secondly, the Father will be in that place, as John says later in chapter 21:
Early in v.3 John writes that God will tabernacle with men in this new age. God, in this case. means all three Persons of the Godhead, as Paul explains in 1Corinthians 15:
Paul explains that when the end of the Kingdom comes, Jesus will hand all rule and authority over to the Father so that the Godhead will become “all in all,” Paul says. This implies that the Three Persons of the Godhead will work as One in this age, though the meaning of Paul’s words is unclear.
Nevertheless, the arrival of the Father does not mean we will "see" Him, as the Bible says He cannot be seen by His Creation:
