Written and media by Kelsey Neier. Christmas: The annual Christian festival celebrating Christ's birth. Jesus Christ is the reason for the season. Remembering Jesus’s birth is what we should focus on first and foremost. We celebrate the birth of our Savior, and find peace in the fact that we will be with him when our physical life is over and spiritual life begins. Jesus is the core of Christmas, but there’s lots of other traditions families have that make Christmas special.
