In the recent storm of books over God and religion--full of name-calling, overgeneralizing, straw-mans, passion, fudging numbers and so on--the civility found in this book is a breath of fresh air. No low blows or cheap shots!? What impresses me most about this book is not only its "friendly" tone (others have that), which dominates the first several chapters and presents a liberal Christian theology (i.e. I can be a Christian and love science and not hate gay people)--what impressed me the most was the psychological studies and survey results that the author presents towards the end of the book. This is the meat of the book I think, where he takes a uniquely psychologists perspective (Michigan psychologist), citing studies that correlate devout religiousness (who go at least once a week) with not smoking, not getting arrested, overall health, happiness/well-being, cheritable giving, volunteerism, and some other random benefitial stuff. To be fair, he also points about psychologically harmful things that are correlated with religion. A nice evening read.
