I think we can relax. There have been a lot of biblical prophecies, as there were Mayan prophecies. Scholars are still arguing about them, but I don't believe the utterances of a so-called holy man from 2 to 5 thousand years ago are always true.
We no longer get all freaked out thinking red tides are an omen of evil, and I don't think we need to do the same about the light bouncing off the earth to illuminate the moon.
As per usual, we should prepare for disasters so that our families are protected, by making sure vehicles are packed with emergency survival kits and by making sure we have enough food and water for a week. (Floods, earthquakes, snowstorms, radiation leaks from nuclear plants). We should also keep coins or cash on hand in case electricity goes out and we can't access our funds.
