I posted on Dr Jensen’s book a few years ago here and here. Jensen takes a refreshingly Christ-centred and gospel-centred approach to revelation: rather than following the traditional approach in systematic theology of defining an abstract concept of “revelation” and moving on from there to scripture, he argues that our starting point should be Christ, whose coming is not only the ultimate self-revelation of God, but provides the model for all divine revelation.
This is, of course, quite a “Lutheran” approach (and shows how “Augsburg evangelical” perspectives are by no means confined to the Lutheran church). I’m reminded of Luther’s statement: “I know of no God other than the one called Jesus Christ”. In the same way, Jensen invites us to say, in effect, “I know of no revelation other than the one in Jesus Christ”.
I greatly preferred The Revelation of God to Jensen’s more “popular” book, At the Heart of the Universe (also in the GBC sale). Dr Jensen seems to be one of those writers (Alister McGrath is another) who is much more confident and effective when writing at a scholarly (but still highly accessible) level rather than a popular one.
