Congregations are increasingly developing partnerships as a way of engaging directly in global missions. One of the most common ways they do this is forming relationships with congregations in other parts of the world. This book looks at the reasons that churches seek out missions partners, how the partnership phenomenon developed, and what beliefs, concepts, structures, and practices inform the healthiest mission partnerships. With insights drawn from a survey of churches from across the country and around the world, this book provides data-driven insights to guide the practice of international congregational partnerships.
