Buchanan is a wonderful wordsmith and his colourful and image-rich prose makes for good reading, but in terms of content, "Things Unseen" is lacking. Granted, "devotional" books aren't usually my cup of tea. I enjoy reading academic theology and then working out the "devotional" side of things on my own. That said, I don't think it's just my perception that something's missing here. For a book on "heaven" Buchanan seems to muddle the intermediate state with the New Jerusalem and the "present heaven" with the new "future heaven" melded to the new earth. In the muddle the resurrection of the saints seems to get lost, perhaps not entirely, but still lost. Buchanan talks about our hope of new "spiritual bodies", but what about the ultimate hope of the resurrection of our physical bodies? Honestly, my heavenly hope is not in a temporary spiritual-only existence in a temporary heaven awaiting its final renovation. I look forward to that great day on which the saints are resurrected to glory and the New Jerusalem irrupts into history as the new heaven descends to join with the new earth. And speaking of hope: I can't help but feel that Buchanan is missing the essential element of doxology. Maybe it's just not here because doxology isn't the book's focus...but, then, shouldn't it be? If my chief hope, my chief source of encouragement, my great longing is simply for heaven as a better place than earth, my faith becomes egocentric, self-centred...it's a "What's in it for me?" faith. Scripture certainly does offer us the hope of heaven as a better place than earth and a heavenly existence as a better existence than the fallen one we live now...but this is all something that pales in comparison to the hope of being restored to full and unbroken fellowship with our Creator, of living in his presence eternally, of heavenly worship, and of living life for his glory as he intended (and which I rejected). It's not that Buchanan is wrong...just unbalanced. Where's the Beatific Vision here?
