But does not the Old Testament promise that God will prosper the faithful? 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 that man can move from a Buick to a BMW. God prospers a business so that hundreds of unreached peoples can be reached with the gospel. He prospers a business so that 20 percent of the world’s population can move a step back from the precipice of starvation.
