I have some news for Mr. Buffet. We get to do this even with people we do not like . The thing we struggle against, and, according to the divine record, the thing all people have always struggled against, is the tendency to make an idol of what we like to do and do best. There are lots of ways to crowd God out of the picture. I don't expect a couple of businessmen in a forum about business to speak of God directly, but any of us can recognize people who are sold on themselves.
History is littered with the failed hopes and schemes of the successfully selfish.
We are just as much heirs to that history as Messrs. Buffet and Gates. I'm sorry in a way that these super tycoons are such easy targets. But maybe God has something in mind in using them. After all, pocket change to them would energize and support the missionary openness and compassion of any number of churches, including this one. Only God can do that.
