Well, there must be some value to informing oneself about the end of days. Otherwise, why would any mystics have ever bothered to write down their visions concerning it?
I do agree that one should be in a state of grace at all times because none of us knows the day nor the hour of our own ends, so we should be as prepared as well as we can be for that.
Personally, I don't care as much about the end of the world as I care about the opportunity to perhaps fight under the King. Our family fought under Clovis and Charlemagne, so it would be a great, great honour to fight under the command of the Great Monarch!! And, we will also have the immense honor of witnessing the selection of the most holy pope!! And that means a true return to the true faith on a global scale, and I would very much like to see that happen! I doubt I'll live long enough, but it's good to know that it will happen one day, even if I don't know what day that is.
