The number 666 in Revelation is symbolically representing a person or an evil entity. It has nothing to do with any inherent goodness or evil of the configuration of the numbers. Christians always seem to want to predict exactly when the end of the world is near. There have been so many false dates set, you d think people would learn from history. Even some of my relatives were taken in by his writings.
Some people simply can t resist the temptation of setting dates.
So far, all the date setters have proven hopelessly wrong. There are given general signs of when these events might occur. And you will hear of wars and rumors of wars. For nation will rise against nation, and kingdom against kingdom. And there will be famines, pestilences, and earthquakes in various places.
