Answer: Okay, just to get the whole record straight about Christains: Christains don't just believe in " Christian humanists believed that in order to change society, first you must have to change humans." I mean yes they do want to make the world a better place, but there's more to it then " Inward Pity," or " Becoming More Pious." The main belief in a daily Christains life is that if you accept Jesus Christ as your Lord and Saviour then you'll be saved from the everlasting tourmet of fire. It's not something to feel an inward feeling of guilt, and to become Pious. Instead, Christains want people to go to heaven, living with joy in the afterlife. Not to make someone have " Inward Pity about themselves," or " Becoming More Pious." Christains believe in everything that their Holy Book says, called the " Bible."
