I'm using this as the basis for a Bible study on John. It is EXCELLENT! Steve Ray is a firehose of questions and information and it is much easier to create a good worksheet by deleting some stuff than by having to come up with it on my own. Between the questions (and each 'question' will have several sub-questions each with one to several Scripture references) are interesting notes concerning the theology, culture, anthropology, word usage, church teaching, history, the thoughts of church fathers, law etc etc etc that flesh out the text even further.
I've heard Steve Ray say that he has a personal library of 20,000 books (a library with a kitchen, he says) and that 5000 of them are on John's Gospel. The Bibliography in this book is huge and so I believe him. There is an extensive index and a cross-reference list to Scripture passages referred to.
Now it's not laid out all neat with questions and blank lines, but if you're willing to work your own way through this, you as the teacher will gain SO much and you will be able to prepare lessons at your class's level of interest. I'm leading a group of about 20 older ladies and gentlemen and you would not believe how they are learning and how interested everyone is! And because the text is SO thorough and so conducive to good conversation, it has taken us a year to finish the first 6 chapters of John and we meet every week!
Very highly recommended. Very.
