A Disruptive Gospel: Stories & Strategies for Transforming Your City by Mac Pier is an excellent book if you want to be inspired by stories and strategies that revolve around large scale prayer and unity conferences. The book promotes these unification efforts as what God is doing and how He is moving to transform cities from the inside out. Such efforts can be beautiful and can certainly be a way that the Spirit moves in cities through churches.
But if you are looking for stories and strategies that focus on how your local church, especially if your local church is not a well-funded and well-connected large church, can implement the gospel on a grass-roots level in ways to impact and transform your city then this book is not going to be helpful and maybe even depressing.
