A husband and wife team of researchers, the founders of Empty Tomb, Inc., in Champaign, Illinois, have tracked American and American Christian expenditures as well as global needs. John and Sylvia Ronsvalle have estimated that $70-$80 billion a year could meet the most essential human needs around the world. “Projects for clean water and sanitation, prenatal and infant/maternal care, basic education, immunizations, and long-term development efforts are among the activities that could help overcome the poverty conditions that now kill and maim so many children and adults.”

The Ronsvalles go on to write, “That figure of $70-$80 billion may sound like anything but good news. God may be generous, you may agree, but has he been that generous? Consider this: If church members in the United States would increase their giving to 10 percent of their income, there could be an additional $86 billion available for overseas missions.”
