advent: it's a birthday

Come on, ring those bells
Light the Christmas tree
Jesus is the king
Born for you and me.
Come on, ring those bells
Every-body say
Jesus, we remember
This your birthday.

— Evie Tornquist, "Come On Ring Those Bells"

I like this song because it teaches exactly what I want my kids to say Christmas is about. It frames the decorations, fanfare, and magic perfectly.
