There are so many movies, cartoons, cards, books, songs, and what-have-you that want us all to remember "the true meaning of Christmas" at this time of year. Usually the theme is that Christmas isn't about getting stuff; it's about giving. Or it's about spending time with family and friends. Or that you can't steal Christmas just by stealing gifts, like the Grinch tried to do.
Hey, I love these Christmas specials just as much as anybody. But none of them gives us the true meaning of Christmas, except perhaps for Charlie Brown.
The true meaning of Christmas is this: God became a man and lived among us in the person of Jesus. Jesus' sole purpose was to become the perfect sacrifice for our sins, so that whoever chooses to acknowledge their sinfulness, put their trust in Jesus and ask him to forgive them for their sins would be reconciled to God and would have eternal life.
It may sound trite, but it's true - Jesus is the Reason for the Season.
