How Can Christians Explain Santa Claus To Their Children?

Can the "Santa Claus" story cause a child to disbelieve in God? Can a Christian parent become a stumbling block to their own child's faith? Are some parents teaching their children to place Santa Claus in a godlike position  as one who can grant all their requests?

I believe it's possible for a child to learn to distrust a parent when they realizes that Santa Claus is a lie.....I believe when we answer "How does Santa get in our house if we don't have a chimney?" or "How can a big fat man fit down that small opening? with a lie when children are old enough to grasp the truth, he or she may think, "Santa's a lie, so the stories about Jesus must be a lie, too."

 Mark Driscoll who's one of America's most prominent young Christian voices who describes himself as "a nobody trying to tell everybody about Somebody who can save anybody....."Driscoll says Christians have three options when it comes to dealing with cultural issues like Santa....We can either reject it, receive it, or redeem it....I tend to agree with Driscoll that the third option is best....As Christian parents we should tell our kids Christmas is about the birth of the Savior, not Santa Claus....every since I can remember most  little children have unintentional worship Santa Claus as the reason for the season....So, what do you tell your kids about Santa Claus?
