man of sin
2 Thessalonians 2:3
2:3 man of sin. “The man of sin” is also called “the son of perdition” because of his being so fully energized and controlled by Satan that he is, in a unique way, the son of the devil. Judas, who was a type of this evil man, was also called “son of perdition” (John 17:12; note also Luke 22:3; John 6:70). The same person is also called “antichrist” (I John 2:18), “the prince that shall come” (Daniel 9:26) and various other names, but especially “the Beast” (Revelation 13:1,18, etc.). According to this verse, his identity will only be revealed after the rapture has taken place (note also II Thessalonians 2:7-9). Soon (perhaps immediately) thereafter, the great day of the Lord will begin on earth, while the day of Christ is also under way in the heavens. See notes on I Corinthians 3:13-15; Revelation 4:1-11.
