I think with a book like this, you can't help but compare yourself to the people in the book. It is part of the purpose of the book. I wonder about myself; whether I would have faith strong enough to die for it. Right now, I don't think I would. So it's interesting to me that all the people in this book have died or lived for there faith. Part of me wants to strive to be like them—living for my faith. Another part is confused.
I think this is a interesting book for most Christians to read because we all want to strive to be more faithful in life. If you are not Christian, I am not sure it will interest you. It might but I think it is a little strong for non-Christians.
