You come across a huge number of people who say that they are much happier and that their lives have turned round now that they believe in God – I’ve just read about one this morning.  I cannot remember ever meeting anyone who said that they were much happier and that their lives were going swimmingly now that they had lost their faith and become an atheist. 

Which is not to say that people do not lose their faith and still have successful lives.  They never, however, make the causal connection between the loss of faith and the subsequent success, a causal connection that those who have found a faith, or rediscovered their old faith, make between their faith and their happiness.  Why is that?
