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.

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.
