The main title is the first of 51 questions the author answers in this book. These are questions about God and Christianity that cover many interesting topics. There are also some many practical questions, like "is drinking alcohol a sin?" or "how should a christian vote?".
The answers are short, but this is what the author proposed to do, to give quick answers to these questions, and not to go into deep detail about any of them. Let's face it, just the first question alone ("Does God exist?"), if analyzed in detail, could produce a whole book (a large one in fact).
In order to provide some more information on the issues he discusses, he also provides links to videos on YouTube that conver the same topics.
It was an interesting and enjoyable read. The short answers keep the reader interested, so I must compliment the author on being able to pen good short answers to some really difficult questions.
This book is a good introduction for christians who want to start studying more about some difficult issues and also to those who want to be more prepared to explain their faith to non-believers.
