McKeown's commentary is a brilliant resource for pastors, teachers and interested lay Christians. it is neither too technical - although there is some Hebrew in the text, it is transliterated and explained - nor too light. McKeown does not proceed through the book verse by verse, but in bite-sized chunks that allow for both explanation and the highlighting of key themes and recurrent motifs. Refreshingly, he is happy not to rehash old arguments and to gloss over matters of academic interest but, arguably, little practical importance (e.g. the documentary hypothesis which, in keeping with the prevailing scholarly mood, gets short shrift).
Following this series' objectives, in the second half of the book (roughly the last 200 pages), he explores the book's 'theological horizons', discussing the unifying themes, the key teaching, the book's relevance today and Genesis' place in biblical theology. The discussions are interesting, well-referenced to other more scholarly literature, and insightful.
This series is excellent, and I eagerly await further volumes.
