Equally important, research about children definitively states that those raised in households where a religious practice is present are more successful in several measurable ways, including school performance, self-discipline and avoiding high-risk behaviors such as drinking, drug use and premature sexuality.
Of course, that's not a reason to practice a religion. We engage in a religious practice because doing so reflects our beliefs and values about God and our relationship to a Supreme Being as we understand Him. To ignore the spiritual development of our children seems to say, "Sorry kid, I'm just not interested in promoting that aspect of your personhood."
All I said in my book is that parents - the vast majority of whom claim to believe in God - should know what they believe about Him, understand their beliefs well enough to teach them to their own children, and then do so. It's simply another aspect of child development that helps to nurture the whole person and offers deeper meaning to life in a world that often seems shallow and superficial.
I wish that reviewer had said this: Nonreligious readers will be challenged by a chapter that asks them to reconsider the spiritual needs of their children but, then again, something so important is worth revisiting from time to time.
