But thou shalt remember the Lord thy God: for it is he that giveth thee power to get wealth, that he may establish his covenant.
Deuteronomy 8:18
What is God's reason for prospering His people? Is it so we can watch bigger TVs? So we can buy finer houses and more luxurious cars?
Establishing God's covenant on the earth and giving to those in need: Those are God's purposes for prosperity!
