In this Fourth Week of Advent, our final days of preparation before Christmas, we ask Christ to forgive us for our sins and, through His grace, to create us anew when He comes. This week is also a time to recollect, to reflect on our Advent journey. If we have let the hustle and bustle of the season get in the way of our spiritual preparations for Christmas, we have one last chance to refocus—and the light of the candles on the Advent wreath can be a symbol of our focus, as well as a symbol of the light of Christ.

In recent times the most common observance of Advent outside church circles has been the keeping of an advent calendar or advent candle, with one door being opened in the calendar, or one section of the candle being burned, on each day in December leading up to Christmas Eve. In many countries, the first day of Advent often heralds the start of the Christmas season, with many people opting to erect their Christmas trees and Christmas decorations on or immediately before Advent Sunday.
