I think there maybe no more timely verses for this world than these from today’s reading:
Watch out and beware of all greed! Your life doesn’t consist of the sum total of your possessions. . . . So don’t go hunting about for what to eat or what to drink, and don’t be anxious. The nations of the world go searching for all that stuff, and your father knows you need it. This is what you should search for: God’s kingdom! Then all the rest will be given you as well. (12:15, 29-32)
I don’t know a modern American Christian for whom greed and anxiety over money is not a temptation at least potentially. That is what comes when you live in a culture focused on money and materialism.
I don’t think there are any great secrets to conquering greed, at least not in our context (maybe you know one?). I only conclude that with prayer and accountability we have to raise this struggle to the conscious level and fight it aggressively. Maybe we ask ourselves why we are purchasing what we do. Maybe we regularly deny ourselves certain intended purchases and extravagances. I know spending time in environments far less affluent helps considerably. So too does the practice of sacrificial giving to others. Another big help is what Jesus says here. Get busy trying to advance God’s kingdom and little by little, over a lifetime maybe, the trinkets of this world become less attractive. At least that is what I am telling myself.
