I think this fact exposes the unreasonable presentation of this doomsday scenario. Some say this will present a unique opportunity to witness for Christ. During times of catastrophe, and this I can tell you from my own experience as one who grew up during World War II, people are out for themselves. Later, in Revelation 16, we read that as a result of the fourth angel pouring out the vial upon the sun, man suffers the greatest heat wave ever. By saying that, I don't mean to imply that Y2K is not something to take precautions against.
Prudence does require preparations and early repairs.
There is much good balanced advice available. However, there's also a lot of outrageous hysteria and hyperbole that's intended more to bolster people's reputations and profit than provide help. No less than the prestigious Economist magazine has noted how strange it is that most of the doom and apocalyptic hype is coming from Christian leaders. Such admonitions were primarily addressed to the people of Israel in The Old Testament. But the moment we place our priority on the visible things, we find immediately many reasons to be afraid, to panic, and believe virtually every false prophet that runs across our path.
