As in Times of Noah: The Flood is upon

Jesus here describes here the condition of the world when He returns in His judgment. They will be caring on with life as usual or normal, marrying, eating and drinking, buying homes, working on jobs, attending school, warring, all types of calamities will be happening. Just like in the time of Noah, those he's preparing for His salvation, that have come out of the world, has been born again looking for His eminent return will be saved as Satan floods the world with False-doctrine carrying away those who received not the love of the truth.
