Jesus said “blessed are the poor in spirit”. A few thoughts and an extension of the analogy:

Poor in spirit = conscious dependence on God, His grace and provision.

Middle class in spirit = religious legalists who think they can do it themselves but still acknowledge transcendent moral values. These people are proud of their religiousity, and look down on those who don’t do as well. The Pharisees fall into this category.

Rich in spirit = don’t need God or effort – the experiencing self is the total and conscious centre of all. They make their own rules.
