But those becoming believers during
the time of the tribulation.....Israel and
Gentiles.... will not be in favor with the
governments of the world.

They will be especially hated by the one-
world government that the Antichrist
will set up.

Jesus tells us that these days will also
be a time of evangelism....possibly the
greatest time!
"And this gospel of the kingdom shall
be preached in all the world for a
witness unto all nations; and then shall
the end come.". Matt. 24:14

The Gospel that is preached at the time
of the Tribulation is called the "gospel of
the kingdom".
