A cause for great gratefulness:
The Pillar Series is my favorite commentary series.
Peter O'Brien is one of my favorite commentators (mainly b/c of his Ephesians contribution).
I'm planning to preach through Hebrews later this year and into next.
Hebrews doesn't have any really good commentaries.
So, you can see why I'm thrilled to hear that the next Pillar volume is Hebrews by PT O'Brien.
