I really enjoy reading Gaffin. His Resurrection and Redemption was excellent. This book is very good as well. He packs a lot into a few pages. He is careful to avoid the either/or idea when it should be both/and. His exegesis is strong and careful. This book revolves to a large degree around II Corinthians 4:16 and what that implies for the anthropology of a regenerate man. He has a great discussion of sanctification, as well as future justification. He avoids the errors of the New Perspective, while still opening up new avenues of thinking. His point about us already being resurrected and our bodies catching up at the end of time was paradigm shifting for me.
