Book Review: Understanding World Religions in 15 Minutes a Day
For anyone that has absolutely no background knowledge (or time for research) on a specific cult, the book will be helpful. Anyone that has been involved in apologetics for any amount of time will find the book too basic.
Each chapter reads like a fair introduction to a larger work on the movements addressed. It would be great for the author to develop each into a full-fledged book.
If you are not interested in investing too much time on learning what each religious cult teaches, this book will give you a sufficient overview. It is always recommended that you read more than one author's take, however, to overcome author's biases (and we all have them!). For a more thorough treatment on the subject, Walter Martin's updated Kingdom of the Cults is a must for every library.
