The advent wreath has been a symbol in the Christian church since possibly the early 16th century. It's purpose is to focus one's heart on Christmas for the 4 weeks leading up to Christmas day. Each candle symbolizes a Sunday before Christmas. The candles all have reflective meanings like Hope, Love, and Joy.
Growing up, my family did the advent wreath every year. It is one of my favorite memories. My mom had a box of mini devotion books and Christian poems and prayer books and each of us would choose something from them to read each night around the wreath. Dad would read a portion of the Bible and we would sing a Christmas hymn. I think the reason it so stood out to me is because this is the only time of the year in which my family would sit down to devotion time together.
While we do devotion time every morning (or almost) in our home, I still like to keep that special advent tradition. Because of my budget our first year, I purchased this booklet that cost only $.99 to lead us. I fell in love with it. It has a new year published each year and this year I got the eBook version for only $.65! It is called the Abingdon Press "Advent: A Calendar of Devotions." You can find it at just about any Christian bookstore, or at www.christianbook.com.
Each evening my husband reads the passage from the Bible. Then I read the devotion. My daughter will usually read the prayer. My son isn't able to read those things yet, so we try to let him help lead the song for the evening and blow out the candle!
I would encourage you to find some way to focus your family's heart on the true meaning of Christmas during this season. I will not rant about the over-commercialization of Christmas, but the truth is that this season is all about Christ's birth. God loved us so much that he sent his one and only Son...let's remember!
