<p>The historical movement known as Pietism emphasized the response of faith and inward transformation as crucial aspects of conversion to Christ. Unfortunately, Pietism today is often equated with a 'holier-than-thou' spiritual attitude, religious legalism, or withdrawal from involvement in society.</p><p>In this book Roger Olson and Christian Collins Winn argue that classical, historical Pietism is an influential stream in evangelical Christianity and that it must be recovered as a resource for evangelical renewal. They challenge misconceptions of Pietism by describing the origins, development, and main themes of the historical movement and the spiritual-theological ethos stemming from it. The book also explores Pietism&#39;s influence on contemporary Christian theologians and spiritual leaders such as Richard Foster and Stanley Grenz.</p><p>Watch a 2015 interview with the authors of this book here:</p><p>&nbsp;</p>
