First, let me begin by defining some terms:
A national superpower is a very powerful nation with heavy influence on its surrounding countries [i.e. the United States, Russia, China, etc.], yet having little control over the affairs of foreign kingdoms.
A world empire is made up of many nations all serving under one sovereign authority who has almost complete control of the known world.
The Seven World Empires
Since the beginning of creation, there have been six of these (nearly) global empires: Egypt, Assyria, Babylon, Persia, Greece and Rome. Each one gained more land, more people and more power than the former. History has revealed that they were all stronger and better than their predecessors. That being said, they all have one remarkable thing in common: they were all temporary.
The pyramids of Egypt are a museum. Nineveh of Assyria became a mound of dirt. The glories of Babylon have long disappeared. Do you even know anything about Persia apart from the movie 300? Greece is bankrupt, and Athens is a pile of rocks. And Rome spread themselves out too thin across the world and eventually collapsed.
However, there is coming a day when the seventh world empire will take its stand on the stages of human history and will forever be the dominant nation. In the coming years we will witness the rise of the final world empire: the nation of Israel. In that day, we will truly be able to say that God indeed saved the best for last because Jesus Christ will be seated on the throne in Jerusalem and will reign forever (Isa. 9:7; Luke 1:32-33). God will finally fulfill His promise to make Abraham into a great nation (Gen. 12:2) and there will never again exist a rival superpower because all nations will be under Christ (Ps. 2).
Israel may not look like much today, but someday God will set them up and establish them as both the national superpower and global empire. After all, Israel is the only country in history to successfully come back from the grave (Ez. 37:1-14). Even though the Jewish people were dispersed over the entire world due to the conquest of Rome beginning in A.D. 70, they maintained their national identity and heritage and regained their homeland almost two thousand years later.
Micah 4:1-2 tells us that, during the future Millennial Kingdom, people from all over the world will travel to Jerusalem to worship the Lord; and that day is quickly approaching. Are you ready for the return of Christ? Are you excited that someday soon He will come and set up His Earthly Kingdom right in Jerusalem?
