In these verses, Paul reminds his readers that initially there had been a hostile response to the gospel in Thessalonica. This hostility was not a new experience for Paul; in fact, they had gone through a similar one in the previous location they had visited – Philippi. The record in Acts 17 states the source of the hostility in Thessalonica – the Jews. But the account reveals that others became involved, including the rough element among the inhabitants and eventually the civil government.
The intention of those behind the hostile response was to hinder, indeed stop, the spread of the gospel. Perhaps they thought that such actions would frighten Paul’s team and cause them to leave. It is the case that they did leave the city, but only after there had been a substantial number of converts, which is a reminder that strong opposition in itself does not prevent the spread of the gospel.
The opponents of the gospel came from different groups within the city – the Jews, the mob, and the government. Luke notes in Acts 17 that those who believed the gospel came from different groups as well – the Jews, others described as devout Greeks (probably Gentiles who had identified themselves with the synagogue), and a considerable number of leading women of the city. The gospel penetrated through the various personal barriers that prevented others from accepting its claims. Paul was fully aware that their work in Thessalonica had not been in vain (2:1).
The accusation made against the new church is an interesting one because it reveals that the residents of Thessalonica were aware of gospel success elsewhere. We can see this awareness when they call Paul’s team, ‘These men who have turned the world upside down.’ The Thessalonians had realised that the gospel has powerful effects wherever it goes, even causing seismic shifts in society. Not only did they appreciate the effects of the gospel, they also grasped a crucial feature of it, which was that there is another King called Jesus. This means that the gospel causes dramatic changes when it is preached with such clarity that causes its opponents to admit its effects and state its central themes.
