Doug the Antichrist is revealed at dan 9:27 and not in the temple....
You have to twist this to fit..... We know the AC when he signs the agreement
It is not that Christians, should the rapture of the Church has not taken place before then, won't know that the person is the Antichrist - but the world won't believe it, because he will be seen as the powerful leader of Europe, who rallied his armies to come to the aid of Israel, when Gog/Magog attacks.
And that God will have supernaturally destroys Gog/Magog, in the eyes of the Jews, will verify to them that he is the messiah, great King of Israel, promised to lead them into the age of peace and harmony.
The Jews many of them believe their messiah appears after Gog/Magog. Their belief based on the teachings of Maimonides is that the messiah will fight the the battles of God in defending Israel.
In Daniel 8, the little horn will wax strong to the south and east, toward the promise land. That is because he will be heading down there to occupy Israel and stave of the Gog/Magog invasion. To maintain the peace and stave off war.
In Daniel 8, in the explanation of the vision, it says in the latter times of the transgressors kingdom (singular) a king of fierce countenance with "stand up". Stand up is a catch phrase for what animals do as they prepare to fight, they stand up on their hind legs and charge each other.
The transgressors are the ten kings of the EU. The latter times of their kingdom, is the EU in its final forum. The little horn in Daniel 8 is the same little horn in Daniel 7, who will come out among those 10 kings of the end times fourth empire. Fourth empires is in the text. The other three empires are confirmed in the body of the Antichrist's kingdom, in Revelation 13:1-2. There are not 7 body parts, because it is not 7 kingdoms in Revelation 17, but 7 kings. The little horn will be the 7th Julio-Claudian leader of the Roman Empire.
