The four weeks before Christmas is the season of Advent. The Christian season of Christmas begins on Christmas Eve and lasts for twelve days, ending on January 6 (Epiphany).
Advent comes from adventus, which means “coming.” Advent is the beginning of the liturgical year and a time in which we prepare our hearts for Christ’s coming in various meanings: the promised coming of the Messiah to the Jews, the coming of Jesus being born in Bethlehem, the promised return of the risen Christ in final victory. Perhaps most of all, this season focuses on the continual coming of Christ into the lives and hearts of believers.
In Advent, we’re reminded of how much we ourselves also need a Savior, and we look forward to our Savior’s second coming even as we prepare to celebrate his first coming at Christmas.
