As the year progresses, the sun appears not only to move from east to west, but also to trace a path farther north or south in the sky. This northerly or southerly travel continues until the solstice, when the sun appears to stand still and begin to reverse course. Today is the winter solstice in the Northern Hemisphere, which, for us, means the shortest day and the longest night of the year. After this, the hours of daylight will increase, and the darkness will decrease.
In an amazing twist of fate, our celebration of the feast of Christmas coincides roughly with the winter solstice, and the beginning of ever-increasing daylight. It appears that according to the Julian calendar, in use at the time of Christ, the winter solstice was regarded as occurring on -- December 25th. I am not versed in the vagaries of calendars; still, it seems noteworthy that we continue to celebrate Christmas on December 25th, and that December 25 falls at a moment of the year when the hours of daylight are just beginning to lengthen.
Coincidence? We know from Scripture that nature reflects God's glory. Is it just possible, then, that (a) Christ really was born on December 25th, and (b) He deliberately timed His coming this way, so that we who walk in the most profound darkness of the year would see a Great Light?
