‘The Bible’ means books. The Bible was written by around 40 different writers.
A long time ago people began to write down what God had done for them. They wrote down things they believed God had told them and made up songs to Him and about Him. The things people wrote were copied into books. Eventually, after around 1,500 years, there were 66 books all about God: story books, poetry books, instruction books and letters. The books were put together in one big book; we call the book the Bible.
Although people wrote the words down, Christians believe God guided the writers and showed them by His Holy Spirit what to write.
