When we lived in Ohio every December in front of the State Auto Insurance Company in the heart of downtown Columbus was built a large nativity scene covering nearly two hundred feet recogning Christmas.
While nativity scenes are not uncommon at this time of the year, this one had some unique features. The scenes make changes every day in December as the night of the birth draws near. On the eve, the donkey, with Mary aboard, and Joseph nearby, arrives finally to the inn in Bethlehem. The manger is empty until the next morning...Then the babe appears, the donkey is barren, the parents are inside, the star brightens. All has changed.
The night we know as Christmas Eve, had closed down Columbus just like it did Bethlehem. And like other unassuming Columbusites, I did not know this scene had been changing daily.
"All is changed; all is bright, round yon virgin, mother and child,
Holy infant, so tender and mild, sleep in heavenly peace, sleep in heavenly peace."
In fact, this Child of God has changed a whole world for the good, and a simple faith in the Christ child will produce a greater faith in the Child-the-Savior of all men.
This reminded me that changes are ever occurring as the Lord prepares His new coming. He advises us in His Word to be ready, and I don't want to simply be a passerby unaware of the daily changes going on before my eyes. I desire to be in total awareness of what is changing so the unexpected to the world will not be a surprise to me.
“And Joseph also went up from Galilee, out of the city of Nazareth, into Judaea, unto the city of David, which is called Bethlehem; (because he was of the house and lineage of David:)  To be taxed with Mary his espoused wife, being great with child.  And so it was, that, while they were there, the days were accomplished that she should be delivered.  And she brought forth her firstborn son, and wrapped him in swaddling clothes, and laid him in a manger; because there was no room for them in the inn.  And there were in the same country shepherds abiding in the field, keeping watch over their flock by night.  And, lo, the angel of the Lord came upon them, and the glory of the Lord shone round about them: and they were sore afraid.  And the angel said unto them, Fear not: for, behold, I bring you good tidings of great joy, which shall be to all people.  For unto you is born this day in the city of David a Saviour, which is Christ the Lord”
