It's a challenging application. I haven't got the exact numbers. But sociologists say that we can have good face to face relationships up till about 250 people, I may be wrong, or the exact number, let's say it's somewhere around that. Now, that means that when you have churches, Mormons limit the size of their churches. So you have that incarnate relationships. Now, here's the point: To the degree that you go wider, say, multivenues, and hypertechnology, or 500 750,000, mega churches in Korea, whatever it is that allows you to go wider might be the super celebrity preaching, or it might be the genius of technology, you will probably live and die by that. Because we're going beyond our human naturalness. We got to think through these things. What do you gain? And what do you lose? Of course, there are times to go beyond that. Thank God for Billy Graham, who didn't need to speak. You know, my great grandfather spoke in the Irish Revival of 1859. And we have newspaper accounts of him speaking to 25 or 30,000, people from the top of a carriage, no microphone, and all that many people heard and many people came to faith, wow, thank God for modern technology, the radio, the television, the Internet, and so on. But we've got to realize that to the degree we go beyond the face to face and the human, to that degree, we're relying on certain things which have their own costs, and we better be aware of them and lean against them. So the mega-churches, they could grow like that, but only if they brought in genuine cell groups of fellowship, that made up for the enormous size of the other, and so on. So we got to keep that discussion, that conversation going all the time. Otherwise, we will be suckered by our own technology.
