As Helen Keller observed, Security is mostly a superstition. It does not exist in nature, nor do the children of men as a whole experience it. Avoiding danger is no safer in the long run than outright exposure. Life is either a daring adventure or nothing. To Michael Frost and Alan Hirsch, so much of how we have learned to experience and understand the faith has been divorced from the overarching adventure inherent in our God and in our calling. This book is a corrective to the dull, adventureless, risk-free phenomenon that describes so much of contemporary Christianity. It explores the nature of adventure, risk, and courage and the implications for church, discipleship, spirituality, and leadership.
