In future ministry James is excited to continue developing missional partnerships with fellow followers of Christ that cross cultural, ethnic, racial, denominational and national boundaries until the unity of Christ's one holy catholic and apostolic Church becomes an observable reality. "There is good work to be done around the world and around the corner."

James has been married to his wife, Lindsey, since 2012. Together they parent four beautiful children. With four children, life at home is always an adventure.
