The word "Bible" really means "Book". The Bible is God's book. It is "inspired" by God. God used about 40 different authors to write the Bible, and He helped them write what He wanted to say. The bible is like a long letter from God written to us. The Bible is God's Word and is completely true.
Some people say that the Bible was just for people a long time ago. Well, it is still god's word and just as true as it ever was. God still uses the Bible to reveal Himself to us, and to show us what is right and what is wrong.
There are several "Translations" of the Bible. The Bible was written in Hebrew and Greek. In order for us to understand it, we need to be able to read it in our own language. The Bible has been translated into English for us. Several different people have translated the Bible to English so we have different translations. Some are more easy to read than others.
