My mom also believes that the weather is going to be very extreme--global warming/climate change is a sure sign that the Great Tribulation/Armageddon is near. She said that there will be 42 pound hail coming from the sky. Not 1 or 2 pounds, not 13 ounces or 19 ounces, but specifically 42 pounds.
My mom also believes that the bird population will increase greatly before the Big A so that they are available to 'help' destroy the wicked ones.
