Books provide excellent background information in addition to the conservative exposition of the Bible. Great resource for pastors, Sunday school teachers, or laymen wanting to better understand the teachings of Isaiah.
I appreciate the textual footnotes. He uses just enough to maintain relevance.
In these books, Young tends to charge into personal/social application or prophetic prediction without looking into what personal/social issues were being addressed by the writer of Isaiah in his historical context. Young will often start down that road and I'll ask myself, "Why is Young on this? I don't even know what Isaiah ment by it - and Young is talking modern politics!" After I notice the logical disjunct, Young will go on for four or six pages elaborating on his (what I see to be a) wrong turn. It's not very helpful as a resource to consult first. I'm finding that in my studies of Isaiah I am consulting many other resources before going to Young (if I still have time for him). If you are looking for a commentator to spend some extended time with, consider the "NIV Application Commentary on Isaiah" by Oswalt. I often disagree with his approach too; but when I do, Oswalt's elaborations don't go on for pages and pages.
These books are well written, but require the reader to have an understanding of English grammar. If you are willing to advance your grammar skills this is a must have. The author is well versed in other persons interpretations and gives sound reasons for agreeing or disagreeing with them. Anyone who wants an indepth perspective of the richness of Isaiah this set is for you. I'm grateful to have acquired this work at such a great price!
