Most people don't believe that. They point to money. They point to their possessions. They point to each other. But security is an illusion.
Nothing is secure if it can be taken away.
Granted, some things are more secure than others. It's not as likely that my roof will cave in while I'm sleeping as it is that I might lose money at the blackjack table. But anyone who listens to the news or reads the paper knows that possessions and people can be taken from us at any time. Even if what we have isn't taken from us, often it is altered in such a way that it no longer makes us feel secure at all. When the payments can't be made on the home we love, then that home is no longer our security.
