When I was a kid, I was often ravaged by poison ivy. The key to poison ivy, once you have it, is not to scratch. Restraining yourself is hard, for your skin itches and you want relief. But scratching only makes poison ivy worse.

Avarice works the same way. We get infected, and we want to scratch, although we know we shouldn't do so. Possessing more and more promises relief, but only makes the situation worse. We keep scratching, but it's no solution. It just makes the situation worse. 

Jesus issues a warning, a warning inspired by a squabble over inheritance, but one that all of us need to hear. He says: "Take care! Be on your guard against all kinds of greed; for one's life does not consist in the abundance of possessions."

Clarence Jordan's translation of this verse brings out its original earthiness. Here's what Jesus says according to Jordan: "You all be careful and stay on your guard against all kinds of greediness. For a person's life is not for the piling up of possessions." In these few words, Jesus rejects much of what keeps our society humming. He warns us against greed, avarice, the desire to possess more than we need, more than we can use, more than we want.  In other words, be content with what you have. Greed will just make your life worse.
