However you package it, however long it lasts, doubt is a fundamental reality of, and an integral part to, faith. In Faith at the Edge philosopher Robert Wennberg explores the reality, nature, and outworking of doubt in the Christian life. Yet, this is not a book about fighting doubt, but is much more about navigating the turbulent waters of doubt that can last a lifetime. Using his own experiences with doubt (which, as a philosopher must have been quite extensive, along with the experiences of exemplary Christian intellectuals such as G.K. Chesterton, Simone Weil, C.S. Lewis, and Martin Marty, Wannberg lays out the theological map of doubt and in doing so helps doubters come to terms with, and understand their doubt in positive and constructive ways.
