This book is supplement to another book which is Wright's commentary
Reviewed in the United States on February 28, 2015
This book is a short series of paragraphs and questions designed for individual or group study. It is not a commentary. It should be considered a supplemental book to N.T. Wright's full commentary "Paul -Galatians and Thessalonians" (For Everyone series) which is the book I would recommend getting first. That book provides a verse by verse discussion with 83 pages on Galatians and 76 pages on Thessalonians.
I am also finding William Barclay's "The Letters to the Galatians and Ephesians" in the New Daily Study Bible series to be equally and perhaps more helpful as a commentary. There are 68 pages on Galatians and 145 pages on Ephesians.
The Wright and Barclay books tend to supplement each other rather than being redundant, and I recommend both. I am finding Barclay's book to be more substantial and satisfying as a scholarly but accessible discussion. Wright's book relates the text more to the contemporary world.
