I use to work for a Christian retailer for several years and was acutely aware of J. Vernon McGee and his works, among a plethora of other writer's resources. In my decision to delve deeper into the Bible by way of commentary resource(s), I chose to lay out the equivalent commentary of the particular book of the Bible from the various authors I chose (McGee, MacArthur, Boice, Henry, Wiersbe, Phillips, among more!) and essentially narrowed my preferences down to two authors: J. Vernon McGee and Warren W. Wiersbe, who were the easiest to understand but still get a rich commentary.
Specifically, this product came as described in a 5-volume set (I also ordered the Index to complete the collection). I'm very satisfied and am sure this will come in handy as an invaluable resource in my library.
