Jesus Christ is the SEED of promise who came, he is the Shiloh who came as scriptures stated below.....
10The scepter will not depart from Judah,
nor the ruler’s staff from between his feet, until he to whom it belongs shall come and the obedience of the nations shall be his. 11He will tether his donkey to a vine, his colt to the choicest branch; he will wash his garments in wine, his robes in the blood of grapes. (Genesis 49:10-11)
The Kingdom of God to come was never about an earthly nation, but is a priestly people from all nations who are gathered before the ruler/monarch Christ Jesus. So it was about people's being gathered onto Shiloh the ruler who would sit on the throne of David as the anointed most high. These people become joined to a heavenly nation called Israel, where the seed of promise Jesus becomes the Israel of God and those who are gathered by him, his Church is the Israel of God.
The Israel of God became separated from the earthly kingdom of man, when Shiloh took the sceptre and ascended up on high to prepare a place in his Father's house for the many peoples of his heavenly nation Israel.
In summary there is no other earthly nation outside of Christ's priestly heavenly nation that is called Israel as far as God is concerned, for all nations including Judah had been gathered onto him and then the Gentiles were joined to them as the gospel went from Judah, the 1st century apostolic Jewish church to the Gentiles and so the two olive trees became the choice vine in the singular, where Jesus Christ became the living vine of the heavenly nation Israel.
It is God who replaced the earthly nation of man called Israel with a heavenly priestly nation under his crowned monarch Christ Jesus, for all messianic prophesy pointed to Shiloh coming and possessing the sceptre as the rightful ruler of Israel. In this respect Jesus is Israel and those gathered onto him, his church is Israel.
Replacement theology is when people try to circumvent God's rule of law by calling an earthly nation Israel. The church of Christ, his bride cannot be superseded by an earthly nation of men, for Jesus said the gates of hell will not prevail against his heavenly nation Israel, his church.
That is why in Revelation 11:1 John is told to measure the inner court of the heavenly nation Israel, which is a priestly ministering nation, his church is the two olive trees before God, inclusive of Jews and Gentiles ministering/prophesying the gospel to the unbelieving world as the symbol of the two witnesses.
From Genesis 49:10-11 and Daniel 2:44 and
Daniel 9:24
Seventy weeks are determined upon thy people and upon thy holy city, to finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and
to anoint the most Holy.
We immediately discern that Shiloh came and was anointed the most Holy, that is the Monarch was Crowned and the heavenly nation was established by blood.
Let me put this in bold, so that no one misses this point.....
The Monarch was Crowned and the heavenly nation was established by blood.
This happened 2000 years ago through the glorification and ascension of Christ into his heavenly Kingdom Israel and the gathering of nations began from the Jewish Apostles that were first gathered onto him as the Jewish remnant 1st century church, then the Gentiles followed in the gathering up to him in heaven.
Jesus isn't going to rule on terra forma, that is on the earth, for he is gathering the people's from all nations onto him to migrate from this temporal life to the eternal life to be with him in his Father's house, which is why he would say......
2My Father’s house has many rooms; if that were not so, would I have told you that I am going there to prepare a place for you? 3And if I go and prepare a place for you, I will come back and take you to be with me that you also may be where I am. 4You know the way to the place where I am going.”
That place that Jesus ascended up into was certainly not earthly, so we need to acknowledge that Jesus didn't come to rule on earth, as the Jews had originally believed and that is why when he as the Kingly high priest Melchizedek had washed his robe in blood as declared in Genesis 49:10-11, the Jews ruled him out as their King and continue to rule him out as their King to this day.
The only way for Jews as a people to enter the heavenly Kingdom of Israel is if they come through the church and declare blessed is he who came in the name of the Lord.
We need to acknowledge that there is only one nation called the Israel of God and any doctrine outside of this nation that teaches of another nation is in fact replacement theology to the Holy Bible in its entirety. The bride of Christ can not be superseded by an earthly nation that calls itself Israel. If it tries to do so, then this would be identified as the abomination of desolation spoken of by Daniel, that is setting itself up as a replacement to God's true Israel under the crowned monarch Jesus Christ. This could only happen if Christians are forced to worship an earthly religious system, the image of the first beast, that is tied to an earthly nation that had the mortal head wound in 70AD, by installing a fake person posing as Messiah king from earthly Jerusalem, in succession to the six previous kings within the Harodean Dynasty.
If a seventh Harod comes in succession to pose as King, then we know that the end is near, watch out!
The Church is Israel because the Monarch had been crowned 2000 years ago, whether the disobedience of the Jews want to accept it or not, is inconsequential to God and a detriment to the unbelieving Jews. If Jews want to be saved, they must join Christ's church immediately before the closing of probation. I believe that they will much to God's joy and my joy.
