Having gotten into this with Vandaler on the other thread, I think I will place my thoughts about the three days here, too. I know that a lot of people don't like the idea of it happening soon, even if they like the idea of it happening at all. I do, and the sooner the better. Let us just suppose that this is indeed the method God uses to chastise us.
In the first place, when we do see it coming, those who have sincerely prayed that His "Kingdom come, His will be done" will rejoice in the imminent fulfillment of His promise they see in the sky. We could sure use some good news these days, too. All others will be given plenty of time to repent. We will also be given time to go indoors to safety.
In the second, and most important, place we will know that these evils will soon be over. Every second of every day people are being murdered, getting abortions, lying, stealing, torturing, plotting mass murders and wars, molesting children and destroying souls right and left. How can we possibly want that to go on and on? How can we possibly want that to go on even one more second?
