Our World

I was just thinking this morning about OUR WORLD...and how much is out there that we know nothing about. What triggered it? Last night I read in the latest issue of National Geographic about a number of language groups that are rapidly loosing native speakers. I don't think I had heard of any of those language groups!! So, looking at the ever changing "Unreached People Group of the Day" I am constantly amazed at how little I know....and the heartbreaking thing is: How will they know? How will they know the Gospel?
