An invitation and a challenge to today’s church leaders to practice preaching that makes a difference not only in the church but in the world. Pastor, professor, and missionary Al Tizon offers chapters grounded in biblical themes for mission and then allows guest preachers to illustrate how those themes may be proclaimed from our pulpits. Features sermons from Greg Boyd, Shane Claiborne, Brenda Salter-McNeil, Ron Sider, and more!
