Purpose Driven?

It is just me or am I the only person living who doesn't get excited about the whole purpose driven movement?
Not being one to jump onto the next best thing(I test as 'Individual/Investigator' in Enneagram), I deliberately chose not to read some of the Saddleback stuff.
Not wanting to miss a wave I flicked through a copy the other day.
There is something numbing about treating kingdom life mechanically.
Do this - and this will happen, deconstruct this - a kernal of truth appears.
The gospel is far more analagous to an organism than to a machine. Mysterious, overwhelming, beautiful, untamed. When I read material like this, the taste it leaves in my mouth is metalic, definable, explainable and dare I say it, non-miraculous.
No doubt, there is valuable information contained in the book, especially for those who have no idea of some of the disciplines of living a good Christian life, but to me it just seems too deductive and consumeristic to sum up the teaching of the smartest man who ever lived.
I have no doubt that Pastor Rick is a good man. . .
