It has been proven for more than 2 generations that an individual human can live WITHOUT God. There are still several countries that still hold that as part of their framework for their society and every man, woman and boys or girls pledge to maintain this Committee Society to continue being Atheists. The other question is: Can a country have it's citizens be followers of God? Can it have some of them be followers of God? How many does God (if there is one) need to be His followers?
We already know that vast numbers of people can and have lived their lives without God. If there is a God and Justice is the foundation of His dominion: How much justice will or is being served, will Rise to the level of being Biblical? Let that percolate through those little grey cells in your brain.
