Well I've never been to any other kinds so I'm not sure what parts are different. There's a lot of singing and the sermons are usually about positive things like welcoming guests and loving people even when they're different. Only God can judge what's in someone's soul so we shouldn't try, we should just strive to follow Jesus' example when he would spend time with tax collectors and lepers and women of the night, without just lecturing and shaming them. The rule is that the door is always open to anyone who wants to go in.
