At our house, these are some ways you can tell that Christmas is coming:
We put up our Christmas tree.
(This was taken last year and we hope to get the tree & house decorated this coming weekend.)
They light the tree in Rockefeller Center in New York City (and I clap every year when the lights go on).
Also, as is our long-time Christmas tradition, we start the Advent Jesse Tree devotions. If you'd like to read some posts from the year that I blogged for each day of the devotional, from December 1 until Christmas Day, click here. You'll be able to click through to all of them (either all in one sitting or you can spread it out).
So here's some audience participation: What are some sure signs for you that Christmas is coming soon?
