How is it possible for any Jew to believe that the anti-Christ is the Messiah? The prophecies for the Messiah in the OT are completely different from the prophecies about the anti-Christ in the OT. If the anti-Christ is from the same people who brought down Jerusalem in the Daniel prophecies, a revived Roman Empire, why would a Jew believe that same person is the Messiah, who must be a Jew from the tribe of Judah, etc.?
If you read all the references to the anti-Christ you’ll see the whole world will be in love with him. For example Rev. 13:4 says they “worshiped the beast and asked, “Who is like the beast? Who can make war against him?” and verse 8 says, “All inhabitants of the earth will worship the beast–all whose names have not been written in the book of life belonging to the Lamb that was slain from the creation of the world.”
That means everyone except the followers of Jesus will literally worship the anti-Christ. And the Jews whose prophecies of the Messiah have always led them to believe he’s merely an extremely gifted man, will think he’s the one they’ve been waiting for. Remember, the anti-Christ will give them peace and grant permission for them to build their Temple. Speaking to Israel Jesus said, “I have come in my Father’s name and you didn’t receive me. Another will come in his own name and him you will receive” (John 5:43) He was talking about the anti-Christ.
But when the anti-Christ tries to persuade them he’s God (2 Thes 2:4), the religious Jews will have the same problem with him that they had with Jesus, that he’s just another man claiming to be God. They’ll reject him then just like they rejected Jesus before.
