The gospel writers were not really concerned with the birth story itself. They were much more concerned with trying to make a point - we have a new beginning. Each Christmas, each of us has a chance at a new beginning. Like the birth of a child, there is a new beginning, a new life to be lived, a new start. For the life of Jesus, we have a new path to follow - a path towards the unconditional love of God which is ours through the Christ Child. It doesn't matter who you are, what you've either done or not done or anything else you might feel - God's love is yours - without question.
That is the Christmas message. The Christ Child is here to show you the hope, peace, joy (and most of all), the love of God which is for you.
Merry Christmas! May God bless you and may you feel God's love embracing you!
