Joseph Smith restored Christ’s church back to the earth in 1830. His birthday is December 23rd so it is a perfect thing to lead up to Christmas. We like to set an oil lamp in the middle of the dinner table (a single candle would work as well). We turn out the rest of the lights. Then we take a few minutes to remind our kids of the importance Joseph Smith and his role in helping us get to know our Savior.
We may conclude the dinner with a piece of birthday cake just for fun.
A great resource for the discussion is a New Era article called “Christmas with Joseph Smith”.
