New Bourbon Shelf
I just got done putting it together and hanging it on my wall. It took approximately 35 minutes to put together and another 15 minutes to hang up. I had to use my own larger wall anchors and screws. I tried the ones that came with it but they didn’t do the job. I am happy with it other than that. Good value and quality materials. As you can see from the picture it holds several bottles and room for more if I want. I think the LED lights look great as well.

Mocks dispensational viewpoints on key Thessalonian chapters.
Format: Hardcover
Very good read. You really walk away feeling like an expert in the Thessalonian Epistles after reading this book because Weima always is searching for theological answers to the questions that arise within the Epistles themselves. You really see the deep unity of Paul's purpose in writing these epistles after reading this commentary. The only problems for me where I did not agree with Weima's conclusions was on dispensational issues in 1 Thess. 4 and 2 Thess. 2. Weima rejected the idea of the rapture without dealing with it at all and then proposed the idea that its talking about a "Hellenistic reception" of a king coming into a city. I don't get it, Weima thinks we do go to the sky meet the Lord in the air and then lead him to the earth, it's so preposterous. It seems like God is in control of this event not man leading Christ to the earth. If he wants to criticize the rapture 'which yes I do believe.' Make your argument. But instead Weima just says things like "so called rapture" without refuting it with logic at all. And then in another eschatological text in 2 Thess. 2 Weima rejects any kind of a literal interpretation and says "We can't actually believe that the Anti-Christ actually goes into a rebuilt Jewish temple as some dispensationalists believe." I'm paraphrasing Weima's words. Weima flat out rejects any dispensational viewpoints on these important verses and doesn't deal with them at all like he does other viewpoints. Other than that I think this was a great read. Highly recommend the book.

Very helpful, lots of detail
Format: Hardcover
Provides a lot of detail, way more than the other commentary I used. That made me have to dig through more information. So I would usually start with my more simple commentary, and if that didn’t satisfy me, I would go to this one, Weima. It gives a lot of detail, when you want that, structure, background, detail, references. It was very helpful when I went to it. I didn’t note finding any “problems” with what I found in this commentary, but I didn’t use it on every passage.

Magisterial
Format: Hardcover
This is a simply magisterial commentary, and almost certainly the best yet on 1-2 Thessalonians. Not only does Weima present a balanced study of the backgrounds and the text itself, but his commentary serves as a thorough catalog of the secondary literature. He is fair and even-handed with positions he disagrees with, often spending more time explaining them than other commentaries do on their own preferred stance. The result is an empowerment of the reader to make their own informed decision, without being left in the dark about where Weima himself stands. This commentary fleshed out and clarified not only my grasp of the titulary subject matter, but also epistolary form and conventions across the NT. It bears the fingerprints of long and careful study, and deserves a place on the bookshelf of scholars and serious laymen alike.

The Best
Format: Kindle
Every time I read this commentary, I get into the state of thinking that fills me with love for the complexity and intricacy of God’s word. The author finds parallels, delves into languages carefully but not exhaustively, and he also deals well with alternate viewpoints. He is so fair with other views that I often draw great benefit from them. To me, these are all hallmarks of a great commentary.
