Today begins the Christmas Season. No the Christmas season does not start in December (or in November). Christmas officially begins on the 25th and goes for twelve days. So I would encourage you not to just celebrate Christmas today, but for the next twelve. Give to others and celebrate the great miracle of the incarnation. I also would encourage you to remember the words of Paul from Philippians.
In your relationships with one another, have the same mindset as Christ Jesus:
did not consider equality with God something to be used to his own advantage;
rather, he made himself nothing
by taking the very nature of a servant,
being made in human likeness.
And being found in appearance as a man,
he humbled himself
by becoming obedient to death—
even death on a cross!
Therefore God exalted him to the highest place
and gave him the name that is above every name,
that at the name of Jesus every knee should bow,
in heaven and on earth and under the earth,
and every tongue acknowledge that Jesus Christ is Lord,
to the glory of God the Father.
Philippians 2:5-11 (NIV)
