I believe Jesus uses Jerusalem here because it was the capital of a nation, the focal point of Jewish worship, governance and culture. Jesus laments for them, not because of the concept of economics or geographical/physical attributes, but because the most of them were lost and rejected Him, especially the religious rulers.
Yes. The scriptures were not written to represent the temporal kingdoms of this word as political kingdoms .But rather a faith in respect to the eternal not seen.
God uses architectural metaphors in parables to represent his bride the church. We a can see that in serval places as the golden thread woven through the whole picture he reveals to us. .
Ye also, as lively stones, are built up a spiritual house, an holy priesthood, to offer up spiritual sacrifices, acceptable to God by Jesus Christ. 1Peter 2:5
And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea.And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband. Rev 21:1
I believe the Jews in respect to their outward flesh were used as metaphors using the temporal land seen (Jerusalem). That as a shadow pointed to the eternal not seen .The new heavenly Jerusalem, is also referred to a Zion . This is according to the instructions he has given us so we can hear Him rightly to understand the spiritual principle hid from the unbeliever.( no faith)
2Corinthians 4:18 While we look not at the things which are seen, but at the things which are not seen: for the things which are seen are temporal; but the things which are not seen are eternal.
This was up until the promised reformation when he restored the order back to the period of time called Judges. The period when there were no outward person, that another person could but their faith in.
Men then walked by faith. But the apostate Jewish elders would nothing to do with the judges .They had become jealous of the surrounding pagan nations that walked by sight, and wanted a king like them.
Zion, used to indicate the Jews and Gentile(no difference) who have been born again and as new creatures have received a new incorruptible eternal spirit. It is the same as the new heavenly Jerusalem the eternal land
The temporal earthly Jerusalem will be destroyed seeing the whole creation including the land suffers as in birth pain to be delivered form the incorruptible bondage to the new incorruptible land . Never again to suffer in a decaying process leading to death and total destruction.
I think Isaiah 62 helps give us some of the spiritual understanding needed to find the meaning of the architectural metaphors.
For Zion's sake will I not hold my peace, and for Jerusalem's sake I will not rest, until the righteousness thereof go forth as brightness, and the salvation thereof as a lamp that burneth.And the Gentiles shall see thy righteousness, and all kings thy glory: and thou shalt be called by a new name, which the mouth of the LORD shall name.Thou shalt also be a crown of glory in the hand of the LORD, and a royal diadem in the hand of thy God.Thou shalt no more be termed Forsaken; neither shall thy land any more be termed Desolate: but thou shalt be called Hephzibah, and thy land Beulah: for the LORD delighteth in thee, and thy land “shall be married” .For as a young man marrieth a virgin, so shall thy sons marry thee: and as the bridegroom rejoiceth over the bride, so shall thy God rejoice over thee. Isa 62:1
Along the same line keeping with using the word city to represent his wife the church . We are informed; “and thou shalt be called by a new name, which the mouth of the LORD shall name.”
That name he named us is Christian in the book of Acts, a word when looking at the meaning without adding another simply mean; “residents of the city of Christ” under its founder Christ, our husband . It seems to lost that way of understanding the purpose for naming us.
It is used just like any other city in respect to its founder. Like the Thessalonians, meaning residents of that city Thessaloniki who founder was named after a wife,Thessalonike , a half-sister of Alexander the great
So we can see that even the new name he named us has to do with architectural metaphors in parable or patterns of that not seen, that represent the people and the new eternal land, as married .
