Next week, posts in this blog will concentrate on the 10/40 Window. Here is a brief introduction of the so called 10/40 Window.
Most of the people groups still unreached by the gospel live in places stretching across the maps of northern Africa and Asia. Christian missions strategist Luis Bush started calling this rectangular area or band: "the 10/40 window." He used that easy-to-remember name because it lies across Africa and Asia from 10 degrees latitude north of the equator to 40 degrees latitude north of the equator.
