In that light--- here are a couple traditions that we have had in our family that help us feel that joy.
First, starting on December 1st, we change our evening scripture study to a focus on Christmas. We have a notebook with a scripture, song, and story for every day until Christmas day. The stories are hokey-- but at least one of us is brought to tears almost every night. Tonight we will be reading our favorite one, sure to make us cry.
We also have a basket that has some of the symbols of Christmas and a scroll with their meaning. (Note: I realize these reasons were created to fit things that are symbolic of Christmas rather than the other way around, but that's ok.) We go through the basket and talk about the symbols.
