The New Jerusalem in Revelation chapters 21 and 22 is a sign of a profound state of man in God's salvation.
The precious stones represent transformed human beings.
The one gold street represents the walk of these transformed human beings in the divine nature of the Father.
Transformed human beings living and walking daily by the "street" of the divine nature of God.
The city is really a mountain of solid gold. The street is a path cut into this mountain of God.
Transformed human beings, through sanctification and transformation, walk in God, by God, in the sphere and realm of the divine nature of God.
In the middle of the one street (and there is only ONE street) flows "the river of the water of life, clear as crystal . As man walks by the divine nature of God God dispenses, pours, and flows His eternal life and nature into this man.
The way the street goes, the water flows. In this walk the Triune God is dispensing Himself into man.
Along the river in the middle of the one street, and on either side, is "the tree of life". From Genesis God placed man before "the tree of life" . That was the tree that Adam should have eaten of rather than "the tree of the knowledge of good and evil"
God has brought the city back to His original purpose in creating man. That is that man might "eat" God. That is that man might take God into his being and become constituted, saturated, and dispensed into by God.
The New Jerusalem represents the MASS PRODUCTION of Jesus Christ. Christ is now multiplied and duplicated in millions or billions of people for the mingling of God and man. That is why they are precious stones. The triune God has transformed them by dispensing Himself into them.
This city is called:
1.) The tabernacle of God - meaning God lives in man and man lives in God. This is a total mingling of divinity and humanity.
Jesus - enlarged as a city.
2.) She is the Wife of the Lamb. She MATHCES Jesus Christ. They two match one another. God wants a Bride and a Wife for His Son. This Wife He ends up with is a collective, a city.
The the Father this "city" is a tabernacle for God to live in man.
To the Son this is a Wife and a Bride to MATCH what Jesus Christ is.
The street is one. There is no Baptist street, no Pentacostal street, no Methodist street, no Lutheran street, no Weslyian street. There is only a street of the divine nature of the Father.
The gold of the city is as transparent glass. Man becomes so transparent and clear that looking into man one sees the eternal God. God is mingled with humanity.
Around the city are "the nations". These are peoples living on the new earth who are not born again but are restored to the state Adam was in before he fell.
The constituents of the city are like the capital of the new heaven and the new earth. You have the sons of God as New Jerusalem and you have the nations which surround her and who walk in her light.
To enter into this holy city New Jerusalem, you must past through gates which are of pearl. No huge oyster of tremendous size has produced these gigantic pearls. This gates of pearl are also symbolic.
Christ, as the oyster at the bottom of the sea produced these gates. Christ came down to bottom of the sea of death, this sin cursed world. On the cross we wounded Him with our sins. And in His love He poured out His life for us. Like the oyster pours out a secretion around the offending grain of sand to produce a pearl, Christ at the bottom of the sin filled world was wounded on His cross by our sins.
Then He poured out His life for us and around us like the wounded oyster. And this pouring out of Christ is the entrance, the gate into the kingdom of God. Because He poured out His life for the sinners He Himself is the entrance into the eternal city.
That is why the gates are seen by John to be of pearls.
