The Gospel of Christ for the Israelites in Their Last Days

Christ’s gospel (good news) to the Israelites in their last days:

“Repent, for the kingdom of heaven is at hand” ~Matthew 4:17 and after His resurrection:
“Repent, and be baptized, every one of you, in the name of the Lord Jesus Christ, for the remission of sins, and you shall receive the gift of the Holy Ghost; for the promise is to you and to your children and to all that are afar off – even to as many as the Lord our God shall call.” ~Acts 2:38-39
“The kingdom of heaven is at hand”, to the Israelites was very good news! Because they had turned their backs on the One who first formed them as a people, insisting upon worshipping the idols of other nations – God had finally given them up to be ruled by other nations, which laid heavy taxing on their finances, sometimes took their children to be slaves or for military purposes, and at times, forbad their customary manner of life. And the main reason they were persecuted for sharing the good news of the kingdom, was because they were under Roman rule with emperors who did not want to give up their powers to another kingdom.
In 70AD when Emperor Vespasian had decreased Earth’s population to where even a child could write the number ~Isaiah 10:19, Christ the Messiah did return at the end of the siege with fury in His face and fought off all the armies that were gathered against His people at Jerusalem . Zechariah wrote, “Behold, the day of the LORD cometh, and thy spoil shall be divided in the midst of thee. For I will gather all nations against Jerusalem to battle; and the city shall be taken, and the houses rifled, and the women ravished; and half of the city shall go forth into captivity, and the residue of the people shall not be cut off from the city. Then shall the LORD go forth, and fight against those nations, as when he fought in the day of battle. And his feet shall stand in that day upon the mount of Olives, which is before Jerusalem on the east, and the mount of Olives shall cleave in the midst thereof toward the east and toward the west, and there shall be a very great valley; and half of the mountain shall remove toward the north, and half of it toward the south….. and the LORD my God shall come, and all the saints with Him.
The kingdom of heaven was brought from the unseen realm in their Last Days ~Isaiah 2:2 and Micah 4:1, and continued physically with Earth’s families gathering once a year at Jerusalem for a week of kamping with the King.
There were three main nations during Christ’s First Dominion ~Isaiah 19:23-25, including Israel, whose citizens walked in the name of the Lord their God. But after hundreds of years with other nations walking in the name of their gods ~Micah 4:5,  the Messiah’s kingdom became like an old, worn garment, so He folded it up and changed it ~Psalm 102:26, Hebrews 1:10-12, to an unseen realm around year 850 AD ~Revelation 20:7-9.
