From Eric Spangler's Blog:
John and Sylvia Ronsvalle have estimated that $70-$80 billion a year could meet the most essential human needs around the world.
Later he quotes them:
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.
Wow...if Christians would just do their part we COULD actually make a difference. I hope the Church can start to live as though it really can make a difference. Mind you this does not even include a gift of time, which can carry our funds even farther.
