Halfway through the Tribulation the Antichrist will literally be indwelt by Satan. Not only will Satan control the Antichrist he will be living inside him declaring, himself, to be god. After the Rapture he will assume control of the world but under the power of the one-world church (Revelation 17:3). During the second half of the Tribulation he will rule the world with absolute authority by the power of Satan. He will blaspheme the Lord (Daniel 7:25, Revelation 13:5-6) and persecute and kill those who are left behind, especially those who get saved after the Rapture (Daniel 7:21, 25; Revelation 13:7).”Let no one deceive you by any means; for that Day will not come unless the falling away comes first, and the man of sin is revealed, the son of perdition, who opposes and exalts himself above all that is called God or that is worshiped, so that he sits as God in the temple of God, showing himself that he is God” (2 Thessalonians 2:3-6).
“So they worshiped the dragon who gave authority to the beast; and they worshiped the beast, saying, “Who is like the beast? Who is able to make war with him?” (Revelation 13:4).
