Who is being sent

The mission force no longer flows in one direction. Brazil, South Korea, Nigeria and the Philippines now send workers into places Western missionaries cannot easily enter — and Filipino nurses, Brazilian engineers and Nigerian traders carry the Gospel on ordinary work visas.

Where they are — and are not

Most missionaries serve among peoples that already have a church. Relatively few work among the 4,490 unreached people groups, where 2.3 billion people still have no meaningful access to the Gospel.
