I did a search for a blog post on this topic and found nothing. The church has an article on ideas for how to prepare for General Conference. I do not expect the writer of the article to think of everything, but I needed to say something about this.
I cannot bring out a memory in my mind, a clean house at the beginning of General Conference weekend, but it has always been a dream of mine. I love to imagine what it would be like. I think it would be so reverent and peaceful!
