It is a program that works for some. If it saves a few lives, what harm can a recommendation do. Without revealing too much personal info, NA helped me immensely in the 90's. Helped me to save my own life. The god thing was downplayed. We used to call Christian 12 steppers "13 Steppers". We discretely mocked those that converted "higher power" to "higher Jesus". We had Wiccans, atheists, and First Peoples that invited us to sweat lodges. It works if you work it! However, beware of 12 step programs in fundie churches. Go to the ones held in parks, rehab centers, coffee shops. Seek out like minded individuals.
God thinks it's fun to confuse primates. Larsen's God!
