I'm trying to decide what I think about Hit N' Run Evangelism.
This is the term I give to Christians witnessing, in a non-personal way, and for which the evangelizers are never seen.
Some examples (I've heard Christians talk about most of these things):
-Christian magazines left at laundromats
-Tracts left here and there and especially on tables at restaurants
-Suggestive movie covers turned around at Blockbuster
-Suggestive books in libraries/bookstores put in other places or dumped in trash cans at the store
-Jesus graffiti. "Jesus Loves You" on overpasses, etc. (This seemed to be more of a phenomenon growing up).
