Church has changed—this book shows how to follow the Spirit out into the community, and reimagine our mission for the 21st century. The decline in mainstream religious denominations is palpable. For years, the question has been: How can we “fix” the church? With thirty years of experience pastoring congregations in small towns, suburbs, and urban neighborhoods in renewal, Alan J. Roxburg knows that the answer is to instead, embrace the church, reinvigorate communities with the Holy Spirit, and re-engage our neighbors with the mission of God. In this timely perspective on the role of the church in today’s environment, he shows how each one of us can become a leader in that mission. Roxburg distills the best missional wisdom for both clergy and laity alike, and offers concrete steps in transforming individual congregations and society. He sheds light on the troubling history that brought us to this point, and how ecumenically and globally we can implement the simple but necessary steps to build from it. An urgent call for Christians to guide any church—large or small—to becoming a vital center for a new spirituality, Joining God is an invitation “to embark on the journey you always wanted to take” (Philip Clayton, scholar, activist and author of Transforming Christian Theology).
