Yesterday, Roger Olson started a new series in his blog, discussing the new book "The Gospel as Center" http://www.patheos.com/blogs/rogereolson/2012/03/part-1-of-a-new-series-responses-to-the-gospel-as-center-by-members-of-the-gospel-coalition Olson intends to go through all of the fourteen chapters of the book one by one.
This may become an interesting read - and everyone may read along in their own copy of "the Gopsel as Center" - but wait: The 2012 Crossway book consists of 14 booklets that serve as explanations to The Gospel Coalition's ( see http://www.thegospelcoalition.org ) Foundation document, also included.
Since all of the booklets are available in Vyrso http://vyrso.com/products/search?q=the+gospel+coalition&Author=Keller%2c+Timothy and the Foundation in Logos http://www.logos.com/product/5163/gospel-coalition-foundation-documents , I acquired all of this in the past!
This PB "recreates" the book by linking its parts from the TOC - I choose to link to the booklets' contents pages for mouse-over.
