@Taka_Merespinner1 To put my two cents in, I've been to Christian churches that do differ from your dad's point of view in his videos respectively, but they were very godly churches that taught me a lot about the Bible and Gospel through musicals, story-telling, and games. They were energetic and fun-filled, yet I also grew spiritually.
"When I was a child, I spake as a child, I understood as a child, I thought as a child: but when I became a man, I put away childish things." (1 Corinthians 13:11 KJV)
Children do not think like adults. If there are tools out there, silly as they may seem, that help children learn the Gospel, then I think they should be used. Children don't learn well having to just sit and listen for hours, even in school. If there is something to help make it understandable, like a song, activity, or story, then they'll be able to learn better.
My old youth pastor would have us play games and told us stories that paralleled Scripture. It helped us to learn while keeping our attention. When I grew older, we still played some games, but we started to sit and listen more. Finally, I'm at the place where I can appreciate a sermon simply sitting and listening. But that's because I had to grow. As I became older, my ability to hold attention grew naturally, and I could now listen to a full adult service.
Also, I meant to tell you on the other topic that you're old co-op sounded a lot like mine (headaches & science teacher). Thankfully, Aetherlight's a good way to connect with other people too.
