Advent is a period of preparation and waiting for Jesus to be born. It used to involve fasting (Catholics and others) until the Christmas celebration, but I don't think many people do that anymore.
There are many variations on Advent, so I'm sticking with the one I like the most. There are four candles for the four Sundays before Christmas. The third one is traditionally rose pink, but nowadays all sorts of colours are used. Each candle has meaning and I've used some of the quotes from Words for Worship to put together my own Christmas Advent idea.
1st Sunday of Advent
The people who walked in darkness have seen a great light;
those who lived in a land of deep darkness on them light has shined.
We join with sisters and brothers around the world, lighting a candle to mark our steps in this Advent journey.
Today, we light the candle of Hope.
