The Bible is not really one book but a collection of books.

The first part is called the Old Testament, which tells us about how God chose the people of Israel.

The second part is the New Testament, which tells us about Jesus and his first followers.

Some of these books are long and others are very short. Some are history books, and others are poetry. Some books are collections of laws, others are letters.

In many ways the Bible is more like a library filled with lots of different kinds of books.

But all of these books are basically about one subject - God!
