“There was no room for them in the inn” (Luke 2:7) when Jesus was born on the first Christmas.
Mary and Joseph went off to a stable or cave, off by themselves, off alone. No space was reserved for Jesus when he came. There was no hospitality, no welcome. There was severe overcrowding in and around Bethlehem, and the local residents and visitors alike were unwilling or unable to receive Jesus when he was born.
