MacArthur is 1 of 3 expositors that I actually trust and read often. He is great with tying other scriptures in context to what scripture he is expounding on. Very solid stuff. I highly recommend these commentaries!!! I have all 30 volumes and it has been the best money spent!!! Besides, christianbook.com has the cheapest prices on these even with shipping!
I love MacArthur. His commentary on the book of Ephesians was well written and easy to read. It is not so deep that only a theologian could understand it and not so shallow that you get bored because it only covers the surface. This book is one that I will refer back to any time that I need some help with some interpretation that I am unsure of. I will definitely be getting more of his commentaries. This book will have a prominent spot in my library.
I have 2 of the e-book commentaries and both exceed my expectations. (Ephesians and 2 Corinthians) They are SO easy to use as e-books..always right on hand. I listen to John MacArthur alot and these commentaries are as if he is speaking to me.
