The missionary is a bridge between two cultures and the churches in those cultures.  Church partnerships provides the framework for the missionary to understand the value of his work.  Sometimes work like raising support and writing newsletters can feel like a drudgery, and simply a means to an end.   But they're not.  They support the grand vision of church partnerships.  A vision for church partnerships can help motivate the missionary in their work to rise above the reduction of their ministry to metrics.  Brotherly affection crosses cultures too.
