Book excerpt: Following the huge success of The Tortoise Usually Wins, 2012, and The Big Picture, 2015, in When Faith Turns Ugly Brian Harris explores why the Christian faith sometimes wears two masks - usually life-serving and transforming, but occasionally escapist, illusionary and even poisonous. What are the warning signs that faith is at risk of turning toxic? What do we mean by the conviction that the gospel liberates? Brian Harris' take on what constitutes life-serving faith is refreshing and will be appreciated by all who would like to be sure that their obedience to Jesus the Christ will help to build a world with a better name.
