I have skimmed this book. I think that Wallis does make some very valid points and says a lot of things you and I agree with. However, I do think there are some things he says you won't agree with and maybe goes too far on. Moral and religious issues do go beyond abortion and gay issues, but not at the loss of those.
He believes social reform issues change history, and uses the "war against poverty" as an example, but abortion is a better example I think. We need to be careful, because just any "social reform" is not necessarily a good thing. We need to be very careful about appearing politically friendly at the cost of the Truth.
It's a dialogue we should be having, however. I'll be very interested to hear your thoughts.

hey jason, first off- congrats to you and roxanne on baby engs! very cool- you are in a for a wild ride.
i just wanted to say wallis' book is a great read, pick it up. i think he does a great job at transcending the categories of left and right in a way that is closer to the heart of the gospel... i've read a chapter here and there, not all the way through though.
peace!
