"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.
