In this book John Polkinghorne and Michael Welker explain how they understand faith in the living God. Between them, they offer a "binocular vision from [their] twin perspectives to yield helpful insight in relation to the important issues." Part of the fascination of this book is how two people with such different backgrounds approach central theological questions relating to the faith they both share. Their concerns are truth rather than polemics, reliability rather than simple certainty. They seek to anchor their thought in concrete particulars rather than abstract generalizations. They ask the questions that trouble the inquiring mind, and meet head-on the challenge as well as the reassurances of belief. This second edition provides a new Preface and updated bibliographies.
