A review of this book is in danger of being as long as the book itself (108 pages).
One specific sentence in the book ably sums up the basic proposition of the author, namely,
"To preach the Word of God well, one must already have cultivated, at a minimum, three sensibilities: the sensibility of the close reading of texts, the sensibility of composed communication, and the sensibility of the significant."
The trouble is, although I didn't always disagree with some of the points, he would have us go back to the era of Shakespearean sonnets and hand-writing letters to get a grip on some of these "sensibilities". I wouldn't like to conclude that none of the disciples could preach, even though they were 'unschooled' men - yet this is a logical conclusion of his rant.
Preaching is clearly important, but we shouldn't be expected to have 'polished performances', as this is surely not the purpose of it. I can fully agree therefore with his statement that "the content of Christian preaching should be the person, character, and work of Christ."
For someone having a rant about communication, as well as anything else, the book does not, in my opinion, 'flow' well.
