Is the 10/40 window term used by Christian missionaries to loosely define areas of the world with "highest level of socioeconomic challenges and least access to the Christian message and Christian resources on the planet" ( https://en.wikipedia.org/wiki/10/40_window ) , and thus areas that need missionaries sort of quaint and grossly oversimplified?
Apart from the glaring error of the 10/40 window Not including the
nation with the highest population of Muslims which is Indonesia, it also
does Not include very poor Central American and some South American
nations.
Furthermore, the computer internet technology advancements that
started around 1995 has led to smartphones, and rapid growth of the
internet so a lot of poor nations even have access to the internet.
Finally, it really is a gross oversimplification because a lot of
European nations that are Culturally Christian like France, Sweden,
Germany, Norway, Denmark, Eastern European nations,etc., have a lot of
nominal Christians and atheists but said nations are Not in the 10/40
window.
Could someone please provide their opinions on said topic?
