I consider myself blessed in that I had a brother who informed me that there was no such thing as Santa when I was about 4 years old. Though his intentions weren't good, it was very helpful that then my Mother told me the truth when I asked her. For starters it was to her credit that I could know that my mother was an honest person when faced with it. Additionally this gave credit to her claim that there was a God.
So many children pass through Christmas with only the thought of what they are going to get. It becomes a very selfish time. In addition it gives the child the idea that regardless of how they've conducted their lives that Santa felt them good enough to get lots of toys. Some see this as that they are cleaver enough to have put it over on an adult (Santa).
Then there is the problem that Aunts and Uncles become objects that they see as suppliers of presents, rather than appreciating their affection for them.
It wasn't Santa that offered the gift. Heavenly Father sent us the gift at the birth of Christ. It is he that should be honored for the idea of giving gifts.
One last thing is in regard family at Christmas time. There are those without family to spend Christmas with. Let me say that we all have a Heavenly Father and an older brother in Jesus Christ. They are there with us at Christmas, provided we invite them in.
I wish you and your families and friends a Great Christmas and a Happy New Year.
