In Matthew, Mark and Luke, Jesus warned his followers that persecution will come before His second coming.

"For false christs and false prophets will rise and show great signs and wonders to deceive, if possible, even the elect."
Some also believe that the antichrist will be charming and not look evil.

He will be someone who people will be convinced that he knows much about ruling the world.
Some teachers believe that this will be in a future world empire coming from a new or revived Roman Empire, similar to the Roman Empire of Jesus' time.

They think the antichrist will come from the Jewish race.
In Daniel's vision/prophecy, he sees a 'little horn'.

This little horn is a ruler or king and speaks of the antichrist: "The ten horns are ten kings who will come from this kingdom. After them another king will arise, different from the earlier ones; he will subdue three kings. He will speak against the Most High and oppress his saints and try to change the set times and the laws. The saints will be handed over to him for a time, times and half a times."
The Antichrist will take over the political and spiritual authority of the world. He will take over by being a very liked political and spiritual diplomat.

He will rule the earth for 42 months which scholars believe to be the last 3 and 1/2 years of the tribulation period. A time in which the world will endure a time of terrible trouble.
