I don't believe God's Holy Word needs a rating. I try to read through the Bible in a year, but it usually takes me a bit longer. One thing I know for sure is that a person must know the author before he/she will ever be able to understand His words. If you don't know the author then the Bible is just another good classic. But if you have a personal relationship with Him then His Word speaks to you like no other book can. The more I read the more I learn about my Savior Jesus Christ.
