To my surprise, I just found out that Zondervan republished my Thessalonians commentary some months back!
You can now buy three full commentaries in one eBook! Mine has a lot of Greek in it, but also much application and thoughts on how to preach the letters. The collection includes Holmes NIV Application Commentary (which I have used, and is fine), and also the Story of God Commentary (which I have not used).
OR you can buy my commentary alone at a discount, from Amazon.
