9.

get religion, Informal. a. to acquire a deep conviction of the validity of religious beliefs and practices. b. to resolve to mend one's errant ways: The company got religion and stopped making dangerous products. It seems like something huge and complicated to simplify into 9 basic points. Religion affects everyone everywhere in the world. Even someone who does not believe in religion becomes defined by that and in a way it is a religion. For many people it defines the purpose of their life. There are so many different types which tie in with many different cultures and languages. How can you simplify one of the most universal and controversial ideas in the modern world?
