What is the name of the day, today? Thursday?
Do you have a problem saying that name? What about Friday, Saturday, Sunday?
All those day names have their roots in pagan worship. Such is our life in this sin-cursed world.
Go and enjoy Christmas to the fullest extent, knowing that you are worshiping God by doing what He said, loving family and friends, and by spreading the gospel, which says very simply, that "when the fullness of time was complete, God sent His son into the world, born of a woman..."
Oh, praise God. I'll set up the Christmas tree, decorate it, hand out gifts, wish others a merry Christmas, and PRAISE my Savior for coming into this world to save souls, mine included!
As an aside, I still recall my first Christmas after becoming one of God's children. I was 27 years old that year. I accepted Christ on my own, with no real live person involved (via radio) and had no real idea about the extent of my salvation until Christmas time came. My soul literally exploded within me, and I SO identified with John the Baptist, who lept in Elizabeth's womb just for being in the presence of Messiah. Songs I sung by rote for almost 3 decades broke me to tears as I contemplated "God with us." What was once commercial and driven only by satisfied wants became an act of worship as I learned to apply God's love to those around me.
I'll agree that all things are not right about our Christmas celebration. Even in the church, we've let a lot of purely secular stuff drive the holiday, but don't throw the baby out with the bath water just because some abuse things. Focus on God and His magnificent grace coming to us, and draw others into the celebration with you! Recall that "feast days" were ordained by God for both for remembering and for the pleasure of His people!
