By far my favorite commentary on Mark. Two other great options are R. Alan Culpepper's commentary on Mark in the Smyth & Helwys series, and David Garland (NIV Application Commentary). I'd say for most pastors, if you have those three, you'll be in pretty good shape preaching your way through the book.

In my opinion, this is by far the best conservative commentary on Isaiah that holds to single authorship. There is a literary and theological sensitivity to it, and even people holding to multiple authorship will find many helpful insights. I much prefer this to John Oswalt and Barry Webb, in particular. Those who find themselves wanting more technical information, and who are working in the Hebrew of Isaiah 40-66, will want to add Shalom Paul's commentary (assuming they are open to learning from critical scholars). Paul does a good job answering the questions that Hebrew translators have as they work through the text, and covers things in greater detail than Motyer.

For any academically rigorous study of Isaiah 40-66, this commentary is basically required reading. A brilliant Hebrew scholar, who I find more careful and detailed than my other technical commentaries (Goldingay, Blenkinsopp, Baltzer). Pastors/teachers will find plenty of theological insights within this commentary as well.

I've nearly worked my way through this whole commentary after doing a sermon series on Revelation. Koester's commentary is absolutely in a class by itself, and should be considered an essential purchase for any serious study/sermon series on Revelation. By far my favorite, out of my many commentaries. Pastors may find themselves wishing it had more theological/practical application-- the AB series doesn't necessarily lend itself to that. But I find Koester far more persuasive, and detailed, than other full-length commentaries (Beale, Brighton). He opened up the book to me.

For most pastors and teachers, this will be the most helpful book on John you buy-- it was for me, in teaching through John. I'd say, if you can only own three, it'd be this, along with Rodney Whitacre (IVP), and probably Francis Moloney (Sacra Pagina). Barclay will consistently move you spiritually, in a way that others may not.

A brilliant commentary. Whitacre uses a narrative/literary approach to great effect, without the reader even necessarily being aware of what he's doing. Warm, practical, and hides its brilliance and sophistication in simple language. Possibly the best commentary on the book; probably the most helpful for anyone preaching or teaching through it.

Gail O'Day is definitely worth reading, but the commentary you want of hers is in the New Interpreter's Bible Commentary series edited by Leander Keck (Volume 8).

I can't imagine trying to teach through 1 Corinthians without this one. Judiciously uses Bruce Winter, among others, and has a knack for getting at what's important, and focusing on what's important. More importantly, he actually moves you spiritually, in a way that some others definitely don't.

So far I've only read his sermons on Joshua, but he is really good. Probably my favorite preacher.

There is more food for thought in here, than in the rest of my commentaries on Joshua put together.
