Christianity is the world's most widely practiced religion, with around 2 billion adherents (followed by [[Islam]] with 1.3 billion, [[Hinduism]] with 841 million, and the non-religious with 774 million). Many non-Christians may think that being a Christian is about belonging to a particular [[church]] or following a certain set of rule. Many Christians however would agree that at its root, being a Christian means to be in a living relationship with [[Jesus Christ]].
