In God’s time, Antichrist (having been empowered by Satan in Revelation 13:2) will reveal himself (2 Thessalonians 2:3,6) through deception and false signs and wonders from Satan (2 Thessalonians 2:9-10). Antichrist will declare himself to be God (2 Thessalonians 2:4).
Antichrist will take over the holy place (the Temple in Jerusalem), pollute the sanctuary, and stop the sacrifice and oblation (offering). He will set up the abomination of desolation spoken of by Jesus and Daniel (Matthew 24:15, Daniel 9:27, 11:31, 12:11, 8:11).
Those who follow Antichrist will receive the wrath of God (Revelation 14:9-11).
