Another one: no raising hands during songs.
It only strikes me now how odd this is, since I’ve visited other churches. Many other Christian groups raise hands during hymns and it seems pretty natural. But JWs never do it. I sometimes think it would be fun to visit an unknown JW congregation and raise my hands during the songs. I’d be curious how they would respond to the dissonance of someone who knows the songs raising their hands while singing “make the truth your own” for example. Some songs would lend themselves to it better than others. I wonder what they would say. I don’t think they’ve got a specific rule against it, but I don’t think they’d like it either!
