After Paul had told the believers at Thessalonica to beware of the rise of the Antichrist and the rise in the spread of error in the last days, in 2 Thessalonians 2:13-3:5, he then urged them to continue to believe the gospel that he and the other apostles had taught. In believing this truth, the Thessalonians were also urged to not move away from the truth but to hold firm to it, to live it out in their daily experience and also to pray for the spread of the gospel throughout the world. Instead of retreating into their shell, the believers were to be active in letting the truth of the gospel of Jesus Christ be known.
