There are many (free) advent resources that are helpful. Here are some resources I enjoy…
Good News of Great Joy (an Advent devotional by John Piper)
The Village Church’s Advent Guide for 2015
On the musical front (not necessarily free):
As well as anything by Folk Angel
My Favorite Christmas Cookie? Chocolate Crinkle
What else? Ever read A Christmas Memory by Truman Capote?
How about Luke 2:1-20? or Matthew 1:18-25?
Have a great celebration of Advent this month!
