One Challenge is a founding member of the OC Global Alliance, comprising thirteen centres around the world who send out workers internationally, across a cultural divide or requiring the learning of a new language.
The Alliance members meet every two years to discuss and decide how best to work together. New opportunities abound, many with possible major impact on whole nations. Alliance members are learning how to collaborate in taking up new ministry.
Guidelines have been agreed on how best to have teams work together, when they have multiple nationalities and diverse church cultures among team members.
