When I'm walking down the street, I frequently pick up trash blowing down the street and stuff it in a garbage can. Usually, it's newspaper or flyers or such. But recently, down near where I work, I've been finding lots and lots of Christian tracts, newsletters, and flyers. And it's not just one or two; it'll be twenty or more. This morning, I cleaned up around 25 newsletters for Alamo Ministries; all in just the space beside our building. Is there some evangelistic principle that I don't know about that involves littering the earth???
