It is unclear how the system was changing in Paul’s day other than the obvious impact that Christianity was having on the Greco-Roman civilization. The New World Translation marginal reference states:
The Greek word here rendered “scene” refers to the “fashion” or “form” of something, the “present scheme of things.” Paul may have been alluding to the theater of his day, comparing this world to a stage where scenes are changing and the actors pass quickly on and off the stage.

The appearance of a man who gave evidence that he had come down from heaven changed the world. Jesus Christ really took centerstage. Even the Devil and his demons knew that Jesus was the Son of God. Their attacks upon him were the long-awaited direct conflict between the serpent and the promised offspring of God. All the angels of heaven were keen to see the outcome.
Paul and his fellow apostles came on the stage as committed followers of the one who 

The world has changed in many ways over the 20 centuries since Jesus and the apostles were on the main stage. Jesus’ exit from the stage may seem like the end of the drama. It was not. In drama there is always a final scene—oftentimes a dramatic ending. Indeed, the heavenly Writer of the divine script has revealed there is to be a momentous, climactic conclusion. The long-departed Son of God is destined to return to the stage. No 
Although Paul is no longer a theatrical spectacle the apostle’s words live on. That is because God’s word is alive. That being true, it is as though the apostle lives too. In fact, Paul spoke of himself as being alive when the curtain on the final scene is raised when he said “We the living who survive to the presence of the Lord.”

Jesus, in fact, presented a preview, a sneak peek—a trailer if you will—of what his 
Not everyone will see the glorious manifestation of the Son of God. Only those chosen beforehand were privileged to see Jesus after he returned from the dead. No unbelievers were permitted to see the resurrected Lord of lords. So it is, only the chosen ones will be eyewitnesses of the presence of the Lord. And just as Peter was an eyewitness to the Transfiguration and afterward gave testimony of his experience on the mountain with Jesus, so too, those who will see Jesus will become witnesses of his presence. How could they not announce Christ’s presence? Will that not make for a dramatic conclusion to the divine drama?
The Devil has tried to rewrite the script. His actors in the charade pretend that the curtain has already gone up on the concluding scene and they portray the presence of the Lord as anticlimactic and really not very interesting or even worth watching. But the Director has indicated otherwise and has advised us to stay in expectation for the curtain call of the grand finale.
As for the scene or stage of this world-changing, never has that been more dramatic than now. The 20th century has been called the American Century. Particularly since the end of the last world war, the Anglo-American dual power has dominated the world. But there is now a sudden change taking place. 
Unknown to most, a covert coup has taken place. No, not in some far away Third World, but in the United States—formerly the leading nation of the world. The government of the 
America served its purpose. God made America great. Yes, God blessed America. But that is over. It was an important prelude to the final scene. Just take note that the nation that was founded by devout Christians, whose currency states “In God We Trust,” whose president once publicly acknowledged that God created all men equal, has come to resemble the iniquitous cities of Sodom and Gomorrah. And they are celebrating sheer perversity and call it Pride. Obviously, Christian America is over. It served its purpose. So has the Watchtower. And now it is time for the tyrants to serve as Jehovah’s punishing agents.
Certainly, the stage is set. The lights are dimming. The curtain is about to go up on the final scene—the grand finale when Christ takes center stage once again. The horses are rearing and snorting fire. The four horsemen are ready to charge.
