Advent is a season observed by Christians as a time of expectant waiting and preparation of Jesus coming into the world. Christians use the four Sundays and weeks of Advent to prepare and remember the real meaning of Christmas.
There are three meanings of 'coming' that Christians describe in Advent. The first, and most thought of, happened about 2000 years ago when Jesus came into the world as a baby to live as a man and die for us. The second can happen now as Jesus wants to come into our lives now. And the third will happen in the future when Jesus comes back to the world as King and Judge, not a baby.
The four Sundays in Advent are celebrated as follows: Hope, Peace, Joy and Love!
