Jerusalem is going to be destroyed. That place in the east that most call "The State of Israel" is going to melt away with a fervent heat at the Second Coming of Jesus. I believe the witness of the apostle John when he said,
"And I John saw the Holy City, NEW JERUSALEM, coming down from God out of heaven, prepared as a Bride adorned for her husband." (Revelation 21: 2)
The apostle Paul agrees because he compared the earthly Jerusalem with the heavenly Jerusalem,
"For this Hagar is Mount Sinai in Arabia, and answers to Jerusalem WHICH NOW IS, and is IN BONDAGE with her children. But JERUSALEM WHICH IS ABOVE is free, which is the mother of us all." (Galatians 4: 25, 26)
The man of God that wrote the letter to the Hebrew saints also said,
"But you are come unto Mount Zion, and unto the City of the Living God, the HEAVENLY JERUSALEM, and to an innumerable company of angels" (Hebrews 12: 22)
If a Jew wants peace, they must come unto Sar Shalom (Prince of Peace) who is Jesus the Messiah of Israel. They must come according to the apostles' doctrine, no other way, no other name. Peace with you all.
The New Jerusalem/Heavenly Jerusalem/Jerusalem which is above was exists before the 21th Chapter of the Book of Revelation. Jerusalem which is above is called the mother of us all. The Church is that New Jerusalem that was spoken about in the Prophets. The Church is the Israel of God, and the saints are the true Jews. This is the messianic interpretation, not the dispensational interpretation. God only has One people, not two. He only has One Temple (the Christ), not the building they are building in that corruptable Jerusalem which is filled with idolatry (Six-Pointed Star). God has only One sacrifice (His Son), not the blood of bulls and goats as they are planning to re-establish.
The first Christians were Jews/Israelites, but not all those that are born of Jewish parents are true Jews.
"Not as though the word of God has taken none effect. For THEY ARE NOT ALL ISRAEL, which are of Israel." (Romans 9: 6)
I also believe as the apostle quoted the prophecy,
"Esaias also cries out concerning Israel, Though the number of the children of Israel be as the sand of the sea, A REMNANT SHALL BE SAVED." (Romans 9: 27)
