Yeah, even non believers.
How can you be sure when you reference 'God', it's the Christian god? Why not the Viking god, or any of the eastern gods? Norse, native American, or any of the ancient religions that aren't practiced anymore's god/s?
Because you live in western society, and our culture conditions you to believe in the Christian god.
If you lived in Pakistan or Iran, you would be referring to Allah or Mohammad. Doesn't that strike you as a little odd? Geographic location determines what religion people generally follow, why is that?
I am sure of this because this 'God's message is to return to the true face of Christianity, if i lived in Pakistan or in Vietnam it would not make a difference of the message, so what are you trying to prove? that just because there are people who are stuck on different beliefs, that all of the religions are wrong? The largest world religions can trace their existence back to something VERY similar, Christianity, the world largest religion has grown the most because it is true, and has seen the least change in what the 'True Christian Religion' of the world is. Unlike Islam, who follow false prohets, and Judaism, who deny Jesus as the savior, and the Virgin Mary being the Mother of Jesus the Savior. As we can see now in Western Civilization, the fall of Christianity due to it's swayed beliefs... just look at American culture, it is so swayed from the 'True Christian Religion' of the world that we can see the fall of it, but through Medjugorje, this 'True Christian Religion' is being brought back and strengthened from the American Christian religion that is far from the truth, and the 'True Christian Religion'
Sorry if that gets confusing, but i'm just trying to stay on topic and not go off and off about the things you, my friends bring up.
