Why do Christians call the Bible God's Word?

Although people wrote the words down we read in the Bible today, Christians believe that God guided the writers and showed them by His Holy Spirit what to write.

Christians believe that the Bible is a very special work of the Holy Spirit and it says what God wants it to say; they believe everything written in the Bible comes from God. Because Christians are so sure that what the Bible says is what God says, they call the Bible ‘God’s Word’ or ‘The Word of God’.
