The revelation of the new Jerusalem implies that the era of the reign of Christianity has expired and the kingdom has been taken away from the Gentiles and restored back to Israel. It means that Jesus has returned the second time, he has been enthroned the only God and King of the whole world, and he is ruling from the Temple Mount in Jerusalem.
"Lord God Almighty, the one who is and who was! We thank you that you have taken your great power and have begun to rule!" (Revelation 11:17)
The Apostles understood clearly that by founding Christianity Jesus effectively took away the kingdom of God from Israel and gave it to the Gentiles. They expected that Jesus will give the kingdom back to Israel after his resurrection.
'When the apostles met together with Jesus, they asked him, "Lord, will you at this time give the kingdom back to Israel?"' (Acts 1:6)
Jesus replied that David in his own time will be responsible for restoring the kingdom back to Israel.
'Jesus said to them, "The times and occasions are set by my Father's own authority, and it is not for you to know when they will be."' (Acts 1:7)
It is not for you to know when they will be: the Christians will not know the time and the hour of the coming of the restored kingdom of David.
The times and occasions are set by my Father's own authority: David will determine the times and occasions of the restoration of the kingdom of David.
Father = David
Note Jesus referring to David as his Father: "I am descended from the family of David" (Revelation 22:16)
Jesus did however restored the kingdom back to Israel in Revelation 21. But without understanding the meaning of the prophesies recorded in Revelation 21 Israel can't possess the kingdom.
Jesus knew that the future is the past, the past is the future, and the present is a cycle revolving between the past and the future. At the time of the founding of Christianity, the kingdom of David was the future. And the Church was the future kingdom of God during the time of the founding of the United Monarchy. This means that David has already done the work of the restoration of Israel described by Jesus in Acts 1:7.
There was an equilibrium between David and Jesus. From David to Jesus, David was the Father and Jesus was the Son; from Jesus to David, Jesus was the Father and David was the Son. This means that David was the son of Jesus just as Jesus was the son of David.
The term 'Son' here implies product.
David is equal to the twelve tribes, since David is the King and founder of the united kingdom of the twelve tribes of Israel. And Jesus is equal to the twelve apostles, since Jesus is the King and founder of the Church.
David represents Israel, since the sum of the twelve tribes is equal to Israel. And Jesus represents the Church, since the sum of the twelve Apostles is equal to the Church.
Consequently, the new Jerusalem is made up of the following two personalities: David and Jesus or Israel and Mary.
Church (12 Apostles) = Mary (female)
Israel (male) = 12 Tribes
Israel was the cube or the Holy of Holies introduced by Solomon and the Church was the stone instituted by Zerubbabel. Therefore the cube represents the first Temple and the stone represents the second Temple. The third Temple (the new Jerusalem) is the sum of the first Temple and the second Temple.
The two cubes constituting the new Jerusalem (the tesseract) are Israel and the Church. And merging the first two Temples to form one Temple is the marriage between Israel and the Church described as the Wedding Feast of the Lamb. The internal cube (the stone) is the Church and the external cube is Israel. Since the stone (the Church) is at the centre of the external cube, Jesus (the ruler of the Church) is the King of the United Monarchy.
"Praise God! For the Lord, our Almighty God, is King! Let us rejoice and be glad; let us praise his greatness! For the time has come for the wedding of the Lamb, and his bride has prepared herself for it. She has been given clean shining linen to wear." (The linen is the good deeds of God's people.)" (Revelation 19:6-8)
The Lord: Jesus
The Lord, our Almighty God, is King: Jesus is King.
Lamb = Israel (bridegroom)
Bride = Church
The new Jerusalem is a holy matrimony between Israel (12 Tribes) and the Church (12 Apostles).
She: the Church
'She has been given clean shining linen to wear' means that Israel is wrapped in Israel. The external cube (Israel) is a linen and the internal cube is the Church wrapped in the linen.
God's people: the Israelites
The linen is the good deeds of God's people: the linen represents the good deeds of the Israelites.
The restored kingdom of David is the octet and the King ruling in Jerusalem is the stone in the middle of Dome of the Rock. The stone is called the Foundation Stone because Jesus is equal to the sum of the twelve Apostles and the twelve Apostles are the twelve foundations of the new Jerusalem. The Foundation Stone is called the Pierced Stone because Jesus was pierced on the side.
