The Advent Wreath

The Advent wreath is a garland of evergreen branches shaped like a circle in which there is no end point. It symbolizes God's unending or everlasting love for us. On this wreath a candle is lit for four Sundays just before the Christmas day  -  a tradition being practiced by many Christian denominations throughout the world.
