We recently had the great privilege of interviewing Dr. Richard Gaffin with regard to his teaching on the theology of Luke & Acts. The content of the interview was essentially a digestion of what is taught in Perspectives on Pentecost. I read this work many years ago, and, sadly, did not benefit from it then as I have now that I am presently preaching through the book of Acts. It is an extremely valuable theological contribution. Gaffin's thoughts on the apostolic ministry, as part of the historia salutis, helps make sense of the foundational nature of the supernatural in the book of Acts. I think you will find this interview to be extremely beneficial. You can listen here.
