If you utilize the NRSV for preaching and teaching in your congregation, then this is a very helpful tool. Each lesson is commented upon in language that is clear and precise and "preachable." In some instances, the content of the commentary presupposes that the reader has some experience with critical or historical examinations of biblical texts, although if one uses the NRSV, that is probably not an incorrect presupposition. Overall, the commentary is clear and thought provoking and helps the preacher/teacher open up the texts nicely.
