I am teaching a bible study in my home and we like this bible and Kay author studies there very in-depth. The BIBLE doesn't give enough room to write things like they ask you to. But other than that it's a great study bible.
I had one for many years(the larger size and still do, since it has my precept notes in it) and finally broke down and got the smaller one and use it now for Precept studying. I also have the ESV which is nice but prefer the NASB version. I would highly recommend this one who is serious about studying the Bible and learning from the text itself what it has to say, not someone else's ideas. "Scripture interprets Scripture" and it does. Go forth and conquer/dig in deeply.
I bought this Bible after doing a Kay Arthur precept study. This Bible is amazing at helping me really study God's Word and to get everything out of passages. I love all the study notes and suggestions on how to study each individual book of the Bible. Best investment!
