Supernatural vs. just natural?

In our recent visit to Nigeria, we were able to minister to between 4000-5000 Nigerian Church leaders. We also handed out between 4000 - 4500 free books, 1000 of which were titled, "AIDS and You" by Patrick Dixon. The crowd appreciated George's ministry but it was a slow start. Everything picked up though when just a second after he stepped off of the stage from his first message (a difficult message to hear), thunder and lightning, incredible winds and torrential rains immediatley errupted. It continued for at least 20 minutes and tore most of the banners hanging up around the colloseum while rain poured in horizontally through to the back. To those inside it was a physical affirmation
of the message and the messenger. They showed
this by erupting into spontaneous worship and prayer and the globe was taken all around the room and held by those there while they interceded for the nations and those greatest needs that lay on the side of the road for us as "good samaritans" to minister to. Those outside who were selling thier wares, mainly books, did not have the same sentiment as much of their merchandise was ruined. Our host returning from town, said that it hadn't rained in town and there was no lightning as she queried us for what happened. Is it possible for God to do something like this - to affirm a message with a physical manifestation? When God acts in such a way, if HE does, is it always going to benefit everybody or will it leave behind a mess for some to clean up. When God shows up, do we expect it to be neat and proper? In a culture that believes in the reality of the supernatural, Christian or not, on a daily basis, you most likely couldn't convince them otherwise. WOW! One more thing, George was just himself, nothing different, nothing altered, just himself, a man who is passionate about the globe, even to the point of wearing global pajamas.
