"For that Day will not come unless the falling away comes first and the man of sin is revealed, the son of perdition," 2 Thessalonians 2:3.

      He is called the 'son of perdition' because the antichrist, as the seed of satan, is destined to destroy and then he will be destroyed by God.

            Because he is total lawlessness, he will be sent to perdition in hell for his sinful rebellion, just as Judas Iscariot, the other 'son of perdition.

 
The antichrist as 'The Man of Sin'.

    In 2 Thessalonians 2:3, Paul promises us that the Great Day of the Lord will not come until the 'falling away comes first'.

         Other prophecies also warn about the religious falling away of the last days.

              The antichrist will only be revealed at the right time after God removes His restraining power.
In Revelation John reveals that 'the beast was captured and with him the false prophet.

    These two were cast into the lake of fire burning with brimstone', Revelation 19:20
Both Isaiah and Paul describe the antichrist as the 'wicked' because he will give himself entirely to satan's evil plan to destroy God's people and laws.

      Despite satan's initial success, the prophets say that Jesus Christ will 'destroy with the brightness of His coming.'
Paul calls the antichrist by this name. "And then shall that Wicked be revealed, whom the Lord shall consume with the Spirit of His mouth and shall destroy with the brightness of His coming", 2 Thessalonians 2:8.
