The Gospel for today's Mass is about the pearl of great price. What's the most important thing in my life? Do I really live my life according to those values?
Money is such a strange thing, because it gets its value from the fact that people value it and believe it has value. In an economics class I once took, the teacher explained that our system of paper money only works because people have faith in it. When the point comes when people no longer believe in it, the system will break down (it's only a matter of time until the dollar suffers the same fate as every previous system of paper money).
But the values of the kingdom are still real no matter if people value them or not. The virtues, all of them, from charity to justice to chastity to honesty, matter to God even if not to all people. They always retain their value.
