The change in the Soviet Union is just one example of the many political kingdoms that have been dramatically altered in just several years of recent history. A reunified Germany, a fragmented Yugoslavia, and a revolutionized Romania are other examples of hastily reshaped countries. Though you may not have been involved in the shakeup of the political kingdoms mentioned above, you are involved in some type of kingdom.
Some people are like a king living in a kingdom of one.
This man had built up his own little kingdom. But God called him a fool because that very night he died and passed into eternity. He left his fortune behind. His kingdom was gone forever, and he had lost his soul as well. As in the political changes mentioned above, some people work for a cause based on an earthly ideal.
