I had a powerful spiritual moment when during the Christmas season my ward and stake invited a Baptist choir to join our wards/stake choirs for a Christmas concert. And the stake president even got up and told everyone that we would be fine to clap in the chapel, normally this isn't protocol. And he wanted to allow it to make it more welcoming to this Baptist choir. They were a well known choir, or still are as you probably know who I'm talking about. My mind currently drawing a blank, but I thought that was awesome. So first the leader of the Baptist choir I think, gave the opening prayer and during it, several in their choir would say amen out loud to what he was saying, which is probably normal. And then the choirs from the wards and the Baptist choir would take turns with different Christmas songs. And then "Go Tell It On The Mountain" came up and I watched as the stake president and bishops were up at the stand and standing and clapping and swaying and the audience did the same, and we never do that during our meetings. So here I was at the back of the cultural hall on the stage, because that was how full the building was, and it hit me big time, the spirit while singing to this song, everyone was singing along.
At the end of the night when my family had a prayer before bed my youngest son was silly and during the prayer as someone else was giving it, my son would say "amen", we got a kick out of it afterwards. He wasn't disparaging at all, just doing what he saw was done during that prayer at the concert. He was old enough that he knew what he was doing.
