That's a straight up commercial.
It is fun to go abroad and see other cultures, and I have personally seen how some cultures are very curious about the bible which makes field service a very different experience for these jdubs. (of course they would stop and listen to any westerner approaching them most likely and certainly to any bible message)
Kind of embarrassing though to have to return to the local village and explain how what you told them last month is completely bogus now. It seems that "new light' has come out on the other side of the world. lol
Oh if it were only as simple as a 3 min video with musical backtracks...
