B&H Academic has a collection of Exegetical commentaries
called: Exegetical Guide To The Greek New Testament. I was privileged to
receive a review copy of Ephesians and I have to say upfront, this is an
amazing commentary. If the rest of the series is anything like the Ephesians
version I'll be getting them all.
The
commentary is based on the Greek New Testament which means that for a person to
get the most out of these guides they must have, at least, a working knowledge
of the language. The guides will still be of some limited use to those who do
not know the language, especially for the preacher because each section
contains suggested Homiletical outlines. These outlines can be used to help prepare
sermons or Bible studies. The commentary begins with a short introduction which discusses things like authorship and date. There is also an outline and a section of recommended commentaries. The introduction is not extensive but is simply a condensed summary. The person interested in more material covering those introductory topics will need to refer to one or more of the recommended commentaries or a Bible Dictionary/Encyclopedia.
The main text dealing with the scriptures proper are composed of a number of sections: "structure", a grammatical diagram of the relevant verses being discussed followed by a verse by verse discussion of the Greek text. The body of the guide is devoted to the lexical, grammatical, and translational issues. At the end of each section there's a subsection called "For Further Study" which lists resources that are helpful for studying topics that have arisen in those verses just commented on followed by the "Homiletical" outline section.
The guide is actually quite small in size, but is so dense. This book will be at my side as I study the book of Ephesians. It doesn't give me everything but does a great job summarizing the material and pointing me in the right direction for further study.
If you are a preacher, I think you would do well picking these guides up, especially Ephesians. If you are not a minister but have a working knowledge of the language this too is a great resource for you. All others will more than likely find frustration and very little help due to the fact that these guides are extremely technical and deal with an ancient language.
