Any ministry or minister errs greatly when they propagate the "prosperity gospel" as God's promise that He will make us healthy, wealthy, and happy. You see, God is not concerned about making us happy, He is focused on making us holy. And that's why the true prosperity gospel is not that you prosper because of the gospel, but that the gospel prospers inside of you. "I will run the course of Your commandments, for You shall enlarge my heart" (Psalm 119:32).
