“A History of God: A 4,000 Year Quest of Judaism, Christianity, and Islam” is an informative book that gives us very beautiful details about the biggest wild goose chase in history, the quest of God. Karen Armstrong, a British journalist is the author of many other religious books and was a former nun and she served as a religious mentor at the University of Boston. She is also the recipient of the TED prize and worked on the TED charter with many. She is also the recipient of many other international awards for intercultural understanding. Through this author gives us an insight into the quest if God from the ages of Abraham to the present. She tells us about revolutions into an idea that was once unknown.  It is an informative, awakening, and enlightening book for someone who is in a quest of God. This is not good for those who have stubborn ideas for religion and is the best one for those who are ready to change their ideas in the light of knowledge. In short, this is an admirable and impressive synthesis that will give satisfaction and enlightenment to thousands of lay leaders.
