Paul’s second letter to the Thessalonians was primarily a follow-up to the one he had previously sent them. The topic of Christ’s return remained the central focus of Paul’s communication. Apparently, the Thessalonians were convinced that Jesus was going to return at any moment. Paul told them, “Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and by our gathering together unto him, that ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of the Lord is at hand” (2 Thessalonians 2:1-2). Paul wanted the Thessalonians to understand that the rapture was only one of a series of events that would take place during the end times. He explained, “Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition; who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God” (2 Thessalonians 2:3-4).
Antichrist’s appearance on the religious scene will be evident by his impersonation of God. This will only be possible because God will remove his Holy Spirit from Earth and allow Satan to be in full control of the world during the Great Tribulation (2 Thessalonians 2:7). Paul told the Thessalonians, “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: even him, whose coming is after the working of Satan with all power and signs and lying wonders, and all deceivableness of unrighteousness in them that perish: because they received not the love of the truth, that they might be saved” (2 Thessalonians 2:8-10). Paul indicated that Antichrist would be successful in establishing his kingdom on Earth because of a deliberate rejection of God’s word. Because unbelief will become the norm, Paul told the Thessalonians, “for this cause God shall send them strong delusion, that they should believe a lie: that they all might be damned who believed not the truth, but had pleasure in unrighteousness” (2 Thessalonians 2:11-12).
Paul’s introduction of the man of sin, whom he also referred to as the son of perdition (2 Thessalonians 2:3), emphasized the uselessness of Satan’s attempt to overthrow God’s kingdom. Paul referred to Jesus’ second coming when he said that the Lord would consume Antichrist with the spirit of his mouth, and destroy him with the brightness of his coming (2 Thessalonians 2:8). The Apostle John described the scene of Antichrist’s defeat in Revelation 19:11-16. Afterward, John said, “The beast was taken, and with him the false prophet that wrought miracles before him, with which he deceived them that had received the mark of the beast, and them that worshipped his image. These both were cast alive into a lake of fire burning with brimstone. And the remnant were slain with the sword of him that sat upon the horse, which sword proceeded out of his mouth: and all the fowls were filled with their flesh” (Revelation 19:20-21).
