" Does not the Old Testament promise that God will prosper His people? Indeed! God increases our yield so that by giving we can prove that our yield is not our god. God does not prosper a man’s business so he can move from a Ford to a Cadillac. God prospers a business so that thousands of unreached peoples can be reached with the gospel. "

― John Piper , Desiring God: Meditations of a Christian Hedonist
