If just the “committed Christians” (defined as those who attend church at least a few times a month or profess to be “strong” or “very strong” Christians) would tithe, there would be an extra 46 billion dollars a year available for kingdom work. To make that figure more concrete, the authors suggest dozens of different things that $46 billion would fund each year: for example, 150,000 new indigenous missionaries; 50,000 additional theological students in the developing world; 5 million more micro loans to poor entrepreneurs; the food, clothing and shelter for all 6,500,000 current refugees in Africa, Asia, and the Middle East; all the money for a global campaign to prevent and treat malaria; resources to sponsor 20 million needy children worldwide. [The conclusion of the authors] is surely right: “Reasonably generous financial giving of ordinary American Christians would generate staggering amounts of money that could literally change the world.”
