Book excerpt: An exhilarating faith life is a tricky business. But ask anyone who's sought after it--from the founders and members of Scum of the Earth Church in Denver to the apostle Paul, from whose letters the church took its name--and they'll tell you it's worth it.In Pure Scum Mike Sares, pastor of Scum of the Earth, takes us along a faith journey, telling the story of how a pretty normal, middle-aged guy met and became friends with Reese Roper and other members of the band, Five Iron Frenzy, and got hoodwinked by FIF and the Holy Spirit into pastoring of a vibrant church full of artists and skater punks.For anyone--pastor, church leader or plain old Christian--who wants to share the amazing grace of God with the ""left-out"" and ""the right-brained,"" Mike's story will show you what this kind of exhilaration looks like, and more importantly, what it costs. It's a tricky business, but it's worth every step and misstep.
