With the advent of the internet, it's absolutely amazing how easy it is to do research on any topic. I remember as a boy being blessed with some World Book Encyclopedias that my parents had purchased. As a result, I had easy access to a wealth of information about practically any person, place or thing.
Yet now, finding information is right at my fingertips on any computer, thus allowing me to learn more about general topics in life within mere moments as I make the effort.
For example, with Christmas rapidly approaching, I did some research on perhaps the most popular Christmas carol, "Joy To The World". This beloved song was penned by Isaac Watts, although the tune is supposed to have originated by George Friedrich Handel. However, I discovered that "Joy To The World" is really not a "Christmas" carol. Consider how the lyrics do not mention anything associated with the nativity, e.g. the manger, Mary and Joseph, shepherds, wise men, etc. Of course, it does mention "the Lord is come" and "let earth receive her king". Nevertheless, this song is written more to describe the millennial reign of Christ which will occur after the Great Tribulation. The Bible describes this future time as a wonderful time of peace and prosperity. I believe there will be no sin at that time. This will be a phenomenal, joyful, peaceful time of unprecedented happiness.
Does this mean that "Joy To The World" should be abandoned as a Christmas carol? Of course not. I think it is certain applicable at Christmastime. Yet, it has a deeper meaning, a wonderful time of peace on earth with Jesus reigning for one thousand years. That will be the ultimate Christmas celebration, far beyond the simple annual festivities around December 25th.
Cancer or sickness can also have a deeper meaning, not just a depressive time of debilitating treatments and suffering. As Joseph said after being reunited with his brothers who had sold him into slavery, "...you meant it for evil, but God meant it for good..." (Genesis 50:20). As I continue to discover, there are deeper and glorious meanings in life, even beyond beloved Christmas carols.
