Only after three and a half years of Dajjal's reign will this confrontation in the Holy Land begin, because before that Dajjal will be busy killing Christians who do not accept the mark of the Beast, and afterwards there will be a war between East and West, Gog and Magog, Russians and Chinese against the West.
While this war is going on, the two Witnesses of the Apocalypse will be preaching for Israel to accept the Messiah, and then the 144,000 chosen ones will come, hidden from the Antichrist, also preaching the gospel of the kingdom to the children of Abraham scattered throughout the world.
The preaching of the gospel of the kingdom will be for the children of Abraham, both Jews and Arabs, for the Gentiles will either already be dead in the fight against the Beast or will bear the mark of the Beast and be soldiers of Satan.
It is important to explain Israel's role in the great tribulation, because the church and Israel are part of the same tree, Yeshua, Jesus Christ.
