Yes! Prosperity Theology! Name It and Claim It! "Dear God, I commit unto You my big plans to win the lottery without even playing it! I know You have the power to accomplish this in my life, so now I await your outpouring of success."
4 The Lord works out everything for his own ends — even the wicked for a day of disaster.
Doh! "So, um, God … scratch that last one, will You?"
