Global Secular Government

I feel that a world with one secular government would never be able to accomplish anything. The fact of the matter is that man is innately sinful and lacks the ability to live under one government even in a "utopia". Especially since there are so many different denominations of differnet worldviews there would be constant strife and disagreement. The reason America's constitution has worked out so successfully is the foundation that it was built on; the Bible. If one tried to create a universal government on a secular worldview it would not be very practical nor would it work properly. In addition how can one create a secular government which contains no foundation for morality. How could they dictate would is right and wrong with out a basis for such assumptions and laws. We would be getting into the idea of postmodernism which believes that everything is relative which makes it impossible to have a government because everyone dictates what is right and wrong in relation to themselves. No one would have individuality because everyone would be held to the same standards. We would be equal which may sound appealing but in the end could lead to problematic situations. The idea of a secular united government is ignorant and naive because it ignores man's corrupt nature. There would be a continuation of corruption and leaders living above the law because no one would be able to correct the leaders of our society. The idea of a united government does not eliminate the possibility for disputes and war but would most likely just increase the potential for it creating civil war.
