In thinking about it all though, it doesn't really matter to me. Of course we don't know the exact day--our modern day calendar didn't even exist at the birth of Christ and our calendar is different from the Jewish calendar. What is important is that we do have a time to celebrate the birth of Christ and a time to teach our children about this miraculous event that God in His lovingkindness allowed to happen so that we who live today could be saved by faith through the blood of Jesus Christ. And that we can use this time to look forward to the day when we will be in Heaven with our Lord. And to remember that the things of this earth are only temporary and that we have so much more to look forward to in Heaven.
