Sarcasm: "Coexist" is in English; it means one world language. Talking in English is worshipping Satan! Even this comment is in English.

Your nickname is @raymond7779. I am assuming you mean that 7779 is the year in which your Bible Prophecy is supposed to come true.

How do you think it is possible that all will be in one religion? There is no one language all people speak, no one city in which all people live.

I think that Christianity wanted to introduce one religion. All people were supposed to accept Jesus as their personal saviour or something, but it didn't come true. All people are not the same. How can all people be Christian, or all people be involved in one religion?

Unless it is one broadly defined religion, like: worship of Nature, or worship of gods and goddesses or none, or meditation. These terms can be applied to almost anything, but again, it doesn't mean that all people are the same.
