Childs develops his well-known & influential canonical approach to deal with some of the most discussed issues in Old Testament theology. Undoubtedly, this volume will capture the interest of any serious student of the OT. Keep in mind that some knowledge of the field is assumed by the author (and this has lead me to some helpful review of former readings, by the way!)
Of course, evangelicals will not be fully convinced by Childs' approach, especially when it comes to the issue of the inspiration of the whole the process of inscriptuation (despite his emphasis on the canon, Childs does not make a distinction between inscriptuation and scribal transmission of the text).
Overall, good book, sometimes hard to read but thought-provoking and helpful.
