I don't think Jesus was "Cadillac" rich. He was rich in His relationship with the people and with His heavenly Father. The NT accounts showed a Man of character, someone who was beyond the love of money.
The extreme "prosperity" teachers would have you believe that it's all about health and wealth in this life, that faith is a force (as in Star Wars), that you have to work your way to God to get Him to bless you, to use Twisted Scripture formulas to exert control over your fate. But what about your immortal soul?
