The Unfinished Task
Jesus' last command was to make disciples of all nations. Two thousand years later that work is real but unfinished — and for billions of people, the reason they haven't believed is simply that no one has been sent.
The 10/40 Window stretches from West Africa across to East Asia, between 10° and 40° north of the equator — home to the majority of the world’s unreached peoples.

What is the 10/40 Window?
A band across North Africa, the Middle East, and Asia — roughly 10° to 40° north of the equator — coined by strategist Luis Bush in 1990 and long called "The Resistant Belt." It concentrates the world's greatest spiritual need in one place:
Roughly two-thirds of the world's people live here.
It holds the large majority of the world's unreached people groups — communities with no established, self-sustaining church.
Around 64% of the people who live here belong to one.
It's home to most of the world's Muslims, Hindus, and Buddhists, the top 50 least-evangelized megacities, and much of the world's poverty and persecution.
Why it changes everything
"How can they hear without someone preaching to them? And how can anyone preach unless they are sent?" — Romans 10:14–15
This is where the fewest messengers have gone and the fewest resources have flowed. That isn't a reason to look away — it's the reason we go.
