The church has always been potentially just one generation away from extinction. But now, with a generation of under-thirty-five-year-olds turning away from institutional expressions of Christianity, churches in the West recognize that they face a challenge that is more urgent and radical than it has been for many generations. In this acclaimed study, the authors identify some of the major storm centres through which churches must navigate, not in order to return to a previously more tranquil world, but to enter an entirely new one. They look at mission, church structures, developing new leaders and mentoring, worship, spirituality and evangelism, and ask how our ministry must change in order to serve a new generation of Christians.
