It might be easier to rule out all desires than to regulate them. The way we handle our desire makes for a lifetime of moral education. A teacher in a laboratory school in England tried an experiment. She gave each of ten children in a classroom a different toy, left them alone, and video-taped their behavior for the next 15 minutes from a hidden observation point. Within 60 seconds, two of the children were pulling at others' toys, while a third child greedily collected the toys those two had laid aside.
Mere children covet one another's possessions.
Yet God has the audacity to say, Don't covet. Coveting is a useless enterprise in many parts of the world, because most material possessions are unattainable. You might thing that we would stop coveting once we're able to have so much, but it doesn't work out that way. Coveting isn't cured by getting. It has virtually nothing to do with what we have or what we need.
