From Acts 17:
The Uproar in Thessalonica 5 The Jews, however, became jealous. So they brought in some troublemakers from the marketplace, formed a mob, and sent the city into an uproar. They raided Jason’s house in search of Paul and Silas, hoping to bring them out to the people. 6 But when they could not find them, they dragged Jason and some other brothers before the city officials, shouting,** “These men who have turned the world upside down have now come here,** 7 and Jason has welcomed them into his home. They are all defying Caesar’s decrees, saying that there is another king, named Jesus!”…
We are upside down again, and nothing is as it should be. If the disciples "turned the world upside down," in the early days of the church, are we near the end of the age when King Jesus will come and turn things right side up?
I think there is more than one eschatological viewpoint that teaches Christ will return to reign on Earth for a 1,000 years. Generally, that seems to be a pre-mill idea, the most popular of which I reckon is pre-mill dispensationalism promoted largely by the Schofield Bible. Before I was a believer, some girls in HS told me the dispensational eschatology. I think the Schofield Bible, with its voluminous margin notes, was created to confuse people.
When I stopped reading/listening to man's doctrines, I was able to see from the scriptures how things go at the end.
