My first observation would be that this is not a book just for people who call themselves worship leaders. This is a book that would be valuable to anybody who calls themselves a Christian. The sheer depth that this book goes into, a depth I wasn't expecting, makes it more than a manual for Sunday morning singing and more of a core text on what should be a huge part of our Christian lives. I should have guessed this from the endorsement on the back. I'd have anticipated having maybe Paul Baloche, Chris Tomlin et al but what you find is rather different. Carson, Frame, Grudem(!?!), Dever and Harris (as well as Townsend and Redman). If that doesn't intrigue you, I'm not sure what will.
The book itself is extremely well set out. The arguments are clear to follow, it flows nicely between over arching themes (which on their own would leave us asking as many questions as we had to begin with) and nitty gritty(which on their own would be so nit picked we'd be arguing that it's only right for his church), it doesn't pretend to know all there is, there's huge amounts of quotations from a vast library of books. Again I say, "This is not what I expected!"
What was most noticeable to me though was the humility with which it was written. In stark contrast to Young Restless and Reformed (which in hindsight stank of pride), at no point do you get the impression that Kaufflin thinks he's a guy whose got it all figured out (I happen to to think He's very nearly there!). Instead he seems far, far, far more interested in showing the reader how `worship' relates to our job as Christians, to glorify our risen King.
His critique of modern `worship culture' is even handed (but quite damning when you realise how far it is from the biblical ideal he presents). I've read it once and can't wait to read it again with highlighter in hand! Really, who ever you are, get hold of this book and read it. I can't say fairer than that!
