The Next Evangelicalism: second thoughts

In our church partnership class, we cover a lot of ground in 10 weeks, from epistemology to American Baptist polity.  We spend one week on justice and one on race, and in preparation of race I have returned to The Next Evangelicalism and assigned the chapter 3, on racism for our class.  Re-reading the book led me to think about my earlier review of it.

For a church, the book is very helpful.  It engages people from a gerneral evangelical background and confronts them with different truth, and for that I am grateful.  I still believe the book resides too comfortably within an evangelical worldview, but I wonder if I have been overthinking it- perhaps it is perfectly written to stir up the average protestant church goer in the US?  In addressing specific issues instead of the overarching viewpoint, there may be a greater wisdom than fighting abstract battles over ideology that would instantly alienate most folk.  As it is, I am using it as a  helpful overview of the racial landscape of American churches that, mercifully includes Asian American folk. (I used to use Divided by Fatih, but it is exclusively black-white.)

Does it concede too much in the end?  I can't imagine any of my classes thinking so as it is really bracing for them.  It also makes me wonder whether or not I miss the point in worrying too much about epistemologies and not enough about addressing the immediate issues in front of me.  So thanks, professor Rah.
