[The Professor]

When God shows His goodness, He likes to see us respond with joy. For example, when God brought the Israelites back from captivity, He told them to hold a festival to commemorate the rebuilding of the temple and the walls of Jerusalem (Nehemiah 8). And celebrate they did!
If God wanted the Israelites to rejoice because of His goodness, would He condemn us for a festive spirit at Christmas? Was not the angel's message to the shepherds one of "good tidings of great joy"? (Luke 2:10)
It's true that the Bible does not tell us to celebrate Jesus' birthday. We don't even know the precise date, and far about the season features a pagan background. But that does not make it wrong to celebrate if Christ is kept uppermost in our lives. We don't think of mistletoe, holly, and evergreens as being pagan any more than we associate Sunday and Monday with the worship of the sun and moon gods after which these days were named. Just because unbelievers abuse Christmastime doesn't mean that we can't enjoy the holiday.
Keep Christ central. Celebrate His birth. Sing carols. Gather for family fun. Even make shopping an occasion for remembering God's goodness. When we love Jesus, He blesses our festivities
WE CAN ENJOY CHRISTMAS, BECAUSE WE KNOW THE JOY OF CHRIST.
