Written shortly after its prequel, 2 Thessalonians was written by the Apostle Paul to reassure the Thessalonian church of the second coming of Christ and to refute the teachings of false prophets. After several forgeries of Paul's letters, the apostle himself alleviated their fears that the time of the end had already begun.
In 2 Thessalonians, there are many prophecies depicting the rapture, the Antichrist and the times of tribulation which are detailed fully in Revelation.
