This type of activity in a war zone is neither wise, nor well advised.
Under the cover of providing humanitarian aid, there is very little likelihood that Muslims are anxious to receive active proselytizing. Surely to gawd, there are converts to be found in areas that are not considered to be delicate war zones.
Statistically VERY few Muslims EVER convert to Christianity because they will simply not embrace the 'three Gods in one Person' concept. Muslims consider that Jesus was an extremely important Prophet, born to a Virgin, but they do not acknowledge divinity or godhood to him. That concept is considered seriously in error to a Muslim. To a Muslim, there is ONE God - 'Al Lah' = 'The God'.
Governments involved in the Afghan mission should dissuade missionaries from going to Afghanistan. It is not helping to improve the situation and it puts their lives in serious danger.
