Paul and his mission group come to Thessalonica and go to the synagogue for three Sabbaths to dispense the gospel of Jesus Christ to these people.  God blesses with some being saved and others that are angry over the gospel and spiteful that it is being proclaimed.  The Lord had given Paul and the men the reputation in a brief time of being those that turn the world upside down.  The Lord is the true world changer and the Sovereign who is the mover and shaker.  The nations rage, Ps.2:1, and we see a little of that in Thessalonica in this passage.
