Do you believe in Violent Bible games.?

I hear we are in Revelations in the Bible where the world could possibly end. Do you think now if you look different you could be considered a non christian. My mom's country is a battle zone now. Nato won't even go there and its not Afghanistan. I go to church and it is becoming this way. My pastor and mom gave me the book Left Behind. Do you think the end of the world is near. Much of the world is a battle zone.
