Luke 2:11
For unto you is born this day in the city of David a Saviour, which is Christ the Lord.
The city of David held a wonderful prophetic fulfillment. Christ the Lord would be both there. But, Christ the Lord is in every city and town and place on earth where a heart cries out to Him for forgiveness and in faith, believing that He is. Then they are born from above, a miracle that is possible any day, not just on Christmas.
