Jesus's words in John 17 represent one of the church's highest values: "May they all be one as you and I, Father, are one." Yet divisions occur from the highest levels of the church to street level projects, often neutralizing effectiveness and undercutting the credibility of Jesus's message. This book helps any believer turn the ideal of John 17 into reality. It provides solid grounding in the principles of partnership, abundant case histories, and empowering "how to" suggestions for lay person and ministry leader alike.
