I grew up a Baha'i. My older brother never had an interest in it and later told me that anyone who believes in God is an idiot. My sister enrolled as a Baha'i, had a Baha'i wedding, then mostly quit participating. Of all the Baha'is in my generation growing up, about half of them no longer identify as Baha'is. Now as an adult, about once a year I see someone leave the Faith, sometimes distant acquaintances, sometimes close friends.
So what does that mean about the truth of the Baha'i Faith? What does the current social climate say about the long-term prospects of the growth of Baha'u'llah's message? How should we view people leaving almost as fast as they're joining? Here are some thoughts.
