The Antichrist is the coming false messiah predicted in the bible. The actual word Antichrist comes from the Greek meaning against the messiah. The Bible contains many verses and predictions of the coming Antichrist, he is called the prince who is to come and is said to be evil and a liar who even opposes Jesus Christ.
According to bible verses when the Antichrist arrives he will create a 7 year false peace in the land of Israel. The bible also says that he will have a false phrophet a man who will perform great miracles for the Antichrist so the people of the world may worship him. The Antichrist will control 10 kingdoms, which many believe to be the European Union. He will also force rich and small free or slaves to have a mark placed on their right hand or on their forehead, and they cannot buy or sell unless they have the mark. He will also place his image in the new Jewish Temple in Jerusalem into the holy of holies and force the Jewish people and the people of the world to worship him.
"He will oppose and exalt himself over everything that is called God, or is worshipped..so that he sets himself up in God's Temple, claiming to be God" Second Thessalonians verse 4
Satan will also enter him and cause even more terror on earth. The Bible even says in Revelations that he will be wounded and seemingly killed but will come back to life and control the world.
Near the end of the 7 years of his rein on earth he will gather the armies of the world against Israel to Armageddon and here Jesus Christ will come and defeat the Antichrist, Satan and False phrophet and send them into the lake of fire to be tortured and tormented for ever and ever.
