Have you ever doubted your faith? Have you ever, deep down in your heart, doubted that God was really present in your life? Or wondered whether everything you believed in as a Christian was false? / Call it existential doubt. Call it ?the dark night of the soul,? as one Christian saint famously did. Whatever you call it, it?s real. It is personal, it is painful, it is distressing, and it can last for years ? maybe even a lifetime. / You are not alone. Such crises of the soul have come upon saints throughout Christian history ? from John of the Cross in the sixteenth century to Mother Teresa in our own time. In fact, there may be something of this God-doubting in all of us. At some point in our Christian walk, most of us have traveled ? or will travel ? this dark path. / In Faith at the Edge Robert Wennberg draws from his own experience with doubt to address such troubling issues. But he also calls upon the wisdom and insight of such figures as Blaise Pascal, G.�K. Chesterton, Simone Weil, C.�S. Lewis, and Martin Marty. Laying out a theologically insightful account of what happens during doubt, Wennberg helps us understand how we can cope with these dark episodes and even profit from them spiritually.
