Bible is the name given to the holy book of the Christians. It is the book containing all the sacred teachings of the Christianity religion. Bible may also be used to describe a book containing the sacred teachings of any religion such as the Koran is the Mohammedan Bible. A book with an authoritative exposition of some topic which is also approved and respected by all the experts in the field is also called bible. There are two versions of the Bible i.e. the Old Testament and the New Testament. These books are supposed to be eminent books of the Christianity religion containing all the sacred teachings which are supposed to be of divine origin. In the words of Helen Keller, “Unless we form the habit of going to the Bible in bright moments as well as in trouble, we cannot fully respond to its consolations because we lack equilibrium between light and darkness."
