About Rooting for Rivals

Christian organizations have come to be known mostly for what we're against. And all too often, that includes being against each other. But amid growing distrust of religious institutions, Christ-centered nonprofits have a unique opportunity to link arms and collectively pursue a calling higher than any one organization's agenda.

Rooting for Rivals reveals how your ministry can multiply its impact by cooperating rather than competing with others, modeling Christlike love and generosity in the process. Peter Greer and Chris Horst explore case studies illustrating the power of collaborative ministry. Writing with vulnerability, they also share their own failures and successes in moving toward a kingdom mindset.

In Rooting for Rivals you'll discover the key to revitalizing your ministry and making an enduring difference in the world.

"I grew up in a West African village that had no word for competition. For me to win at the expense of another’s loss was simply inconceivable. And so it should be in the building of God’s Kingdom. Impossible? Read how it’s being done in outstanding ministries across the globe!" —Dr. Wess Stafford, president emeritus, Compassion International

"I love the African quote, 'If you want to go fast, go alone. If you want to go far, go together.' It applies especially well to the power of community in Kingdom work. I’m grateful to Peter Greer and Chris Horst for celebrating Christ-centered teamwork and collaboration in Rooting for Rivals. This is an essential read for Christian ministry leaders who want to model countercultural unity and generosity in how we obey and serve our Lord." —Richard Stearns, president, World Vision U.S., and author of The Hole in Our Gospel

"Peter Greer and Chris Horst have done it again—their collaboration has produced another provocative volume, this one designed to challenge the dominant paradigm of competition, which hinders the flourishing of many ministries and nonprofit organizations. Written with candor, humor, and wisdom, Rooting for Rivals is a must-read for anyone who seeks to lead in a manner characterized by humility, generosity, and grace. During these times of discord and division in the church and society, Greer and Horst provide a welcome roadmap for cooperation and bridge building." —Kim S. Phipps, president, Messiah College

 "Rooting for Rivals is a convincing and convicting call to leave behind the mindset that we compete against one another within the Kingdom of God. Peter Greer and Chris Horst present a revolutionary understanding of what it means to advance the mission of God. This book is a must-read for every leader who wants to honor the Lord." —D. Michael Lindsay, president, Gordon College

"With solid research, engaging stories, and theological acumen, Peter and Chris present a kingdom-shaped vision for leading Christian organizations in a distinctly Christian way. In a time when many faith-based groups are facing legal and financial pressures, it is my hope that the cooperative spirit they envision in this book takes off and proves to be a source of fruitfulness and abundance for Christian institutions in the century to come." —Katelyn Beaty, author of A Woman’s Place and editor at large, Christianity Today

"Rooting for Rivals is full of practical and compelling guidance for effective partnership in and out of the church—a reminder that the scriptural counsel to look not only to our own interests but also to the interests of others applies even when those interests are closely aligned." —John Inazu, author of Confident Pluralism
