The Antichrist will step up in power at the
start of the Tribulation. He will look and
act like he is a friend of Israel and the world
will admire him.

But he will betray that friendship in the
middle of the Tribulation. The Bible says he
will break the covenant with Israel. That
will cause a rebellion for they will no longer
be friends because he sets himself up in the
Temple and says that he is God.
