This book is for those who identify themselves, when asked, as a 'Christian believer.' They may say they are Christians because they went to church with their parents as they grew up, and continue to go every once in a while or on Christmas or Easter. They may have gone to a Christian school, been baptized, had first communion or said a prayer when they were young. It is for anybody who, when asked "what religion are you?" would answer that they are "Christian."
