This is the best study Bible I have ever read, and I have to think it is one of the best ever made. I have read it all the way through two times in about 20 years.
Take note that this Bible is broken up into daily reading, moving forward through the books of the Bible in order, starting with Genesis from the Old Testament, some of Psalms and some of Proverbs, and then starting with Matthew in the New Testament. If you are looking for a reading plan, this is a good one. You don't have to worry about keeping up with the dates (e.g. January 1, 2, etc.). I just read it one day at a time; the reading selections are not tied to the calendar. This can make it harder to flip through this Bible to find the book and chapter you are looking for. You would be better off having a regular Bible to reference for that purpose.
What makes this study Bible uniquely great are the 30 Life Principles from Dr. Stanley that are distributed throughout. Growing up listening to Dr. Stanley preach, I have heard several of these. Having the specific verses referenced and a full page essay written about each one really helps to hammer it home into memory.
There are also a few thousand in-line notes and highlights with further "life lessons" that help to add context to the reading. This is not a full study Bible where nearly every verse has a footnote. It is focused upon drawing out God's wisdom and applying the Bible's truths to your daily life. In particular, there are hundreds of God's promises highlighted and called out.
If you have the chance, I would recommend purchasing a hardcover version of this Bible. I have a paperback and it is starting to become a bit worn on the outer cover, although the print quality of the pages is superb.
Dr. Stanley and the editors of this study Bible have really made the truths and implications of the Bible applicable to any reader, without too many words or without watering down the original NKJV translation. I would recommend this study Bible to any age reader, perhaps older than 15, and to any believer at any stage in their walk with God.
