Martin Luther expresses his appreciation of Christmas, not just that Jesus was born, but how and to whom he was born:

If Christ had arrived with trumpets and lain in a cradle of gold, His birth would have been a splendid affair. But it would not be a comfort to me. He was, rather, to lie in the lap of a poor maiden and be thought to be of little significance in the eyes of the world. Now I can come to Him. Now He reveals Himself to the miserable in order not to give any impression that He arrives with great power, splendor, wisdom, and aristocratic manners. But upon His return, on that Day when He will oppose the high and the mighty, it will be different. Now He comes to the poor, who need a Savior; but then He will come as a Judge against those who are persecuting Him now.  ~ from a sermon from 1530

Remember Christ dwelt with us in humility so that we might approach him receiving the covenant of peace which he secured for us by the blood of his cross.  (Colossians 1.19-20)
