Luxuries and necessities
Which are luxuries? Which are necessities? What is necessary for you to survive? For you to take part in your society? For you to live a life of wholeness? How different are these? What are you praying for when you say, "Give us this day our daily bread"?
Consider how many of the things you call 'necessities' are really necessary. Remember that 70% of the world's population has never made a phone call, and that electricity has only been available for the last 150 years. But toilets with water flushing were around at least 5000 years ago, and even the most technologically primitive peoples have jewellery. What does this say about human needs?
