This slim book is part of a series of books authored by Arvind Sharma in the area of the philosophy of religon. The others are from Hindu, Jaina, and Advata Vedanta perspectives. This book deserves five stars as Dr. Sharma fulfills his obligation wonderfully, which is to present what Buddhists think about various religious concepts, such as the existence of God, the problem of evil, and how to verify beliefs.
In line with that last concept, how to verify beliefs, one of the ideas I took from this book is that we need to step aside from what we believe to be true, and wonder why nobody else has caught on, to see if it makes any sense to anybody else. How do you know that sugar is sweet, because it's sweet to you? Not all people find sugar to be sweet. How can we make our truth sensible to others? How can others help us to find the truth?
Dr. Sharma makes many references to three books in his study here, so I would recommend before starting this book to first make yourself acquainted with them. Those books are "A Buddhist Critique of the Christian Concept of God" by Gunapala Dharmasiri, "Philosophy of Religion" by John Hick, and "The Message of the Buddha" by K. N. Jayatilleke.
Please note: this is a scholarly book in the area of religious studies, if that wasn't obvious already.
