In the New Testament, when disciples were sent out on mission, it was almost always as a team in which people had different roles and responsibilities. There were over 80 people that worked with Paul in some capacity in his mission work. Some were considered co-equals, some subordinates, some worked in a local setting and others travelled with him. There were men and women, marrieds and singles, some were left behind to continue the work, and others helped him write letters as his scribes and secretaries.
The New Testament example tells us that there are as many different roles to play as there are giftings and skill-sets. Each missionary team will look different because the roles will depend on the people, the location, culture, and type of ministry. In just one team, the roles and skill-sets could range from church planting (which is not just a pastor), theological education, business as mission/entrepreneurship, agriculture, arts, technology, education, healthcare, and more. There are many avenues that allow us as cross-cultural disciple-makers to break through barriers and share the Good News of the gospel with the peoples of the world.
