I bought both Vol. 1 and Vol. 2 of these study books in order to have coverage of the whole Gospel of John. William Barclay is, of course, a well known and respected writer, Bible scholar and preacher. I needed them to support what I was preparing for a series of sermons from John. I wanted something rich in detail, reliable in information and viewpoint but also practical in application. Barclay fulfils this perfectly. The format of the book is to break the text into short sections and then offer a commentary on that part of the text. The book can easily be used for (undated) daily devotions but works just as well as a reference source and study aid - my own usage. Barclay has accrued an army of readers and admirers over the years and this book, which is a part of his series covering the whole of the New Testament, is excellent.
These William Barclay studies of the Bible are tremendous help when preparing for our Housegroup studies. Especially for background information of the period. His explanations of the text are clear and easy to read and give depth to the Gospels.
Bought this (both volumes) for my wife, who is the Godly one in our family, and she was spellbound from the start. All I can do is testify to the design and quality of the product, and applaud the price.
