One government can have many kings..as the bible uses the term... your point has little biblical weight. And you have to ignore so many other scriptures to come to your conclusions... We know there will be one economic system ..we know the UN gains power everyday and many are attempting at ever turn to set up a form of world government ...these things cannot be denied by a honest person.
In reference to one of Rachel's posts, like Mitspa said, the bible DOES speak of (or predict, to use Rachel's term) a new world order. Just because the bible may not blatantly predict it, doesn't mean it isn't happening. If you read scripture correctly and in context, you'll see it predicts certain disasters such as earthquakes, tsunamis, tornadoes, even 911 and the Exxon Valdez oil spill. The bible talks of events that happen today, such as children and women being killed, adultery, incest, etc ad nauseum..
I'm trying to see what you see, because what you saw must be seen by us, to fully see "it", right?
