The 10/40 Window is a well-known term, and in this episode we’ll meet Luis Bush, the man who coined this phrase which has shaped missions-thinking for a generation. We’ll learn about how the 10/40 window has some of the worst suffering on earth, the greatest resistance to the Gospel, and the least-reached population on the planet. From this perspective we’ll gain a renewed vision of how to invest our time, prayers, and resources to reaching the unreached. Be a part of this personal and thought-provoking conversation.  Listen, learn and share what you find…Until All Have Heard.
