The Holy Bible is the book that has shaped Western Civilization for more than 2000 years, but it's often difficult to find a translation that works for the modern reader. (Can ye readeth the King James Version without thy head aching?) The New International Version and this mass market paperback make the Bible easily accessible to the modern reader. The type is a little small, and hopefully a Large Print version will be made to the average consumer.
Reading this book is essential. Even if you're an agnostic, an athesit, or what have you, the writings from Genesis to Revelation are very compelling. If you read the reviews for the King James Version elsewhere on the site, you'll see there are many who give it a poor review simply because they're atheists. But when you get down to the basic substance, the messages of the Bible, (the way people should treat one another, not judge others, try to improve themselves, love your neighbor, don't commit murder, put others' needs before your own) are really difficult to hold in contempt. Indeed, Matthew 5-7 could easily be marketed as a self-help book.
The Bible is timeless, and at least this translation and edition help the modern reader. For what it's worth, it will probably take roughly one year to read the Bible from cover to cover, but given its importance, it's worth it.
