Today I received an e-mail from Dr. Greg Harris, Professor of Bible Exposition at TMS, concerning his upcoming book The Darkness and the Glory: His Cup and the Glory From Gethsemane to the Ascension. His previous book The Cup and the Glory: Lessons on Suffering and the Glory of God was phenomenal as his in depth exposition and application challenged me deeply. He has made a sample of the first three chapters available in PDF for download here; I would highly recommend reading this sample and then buying both of these books. I will post to let you know when the newest work is available to purchase
I also recommend listening to the following teaching series at Grace Community Church where Dr. Harris walks through The Cup and the Glory.
