Personally I hate the term "business as usual" because I don't think it truly describes what we are seeing today. As you stated above with the soon to be financial collapse, global immorality, USA defection of Israel, global violence, global chaos, then we all of a sudden have the rise of earthquakes & volcanoes in various places, rise of many old and new plagues globally, and the coming famine . . . this all is not business as usual.

They did eat, drink, got married Luke 17:27, Matt 24:38 We currently have a society that is morbidly obese, that also loves to drink. We have a mixed society of unsaved that either just shack up & live together and those that get married but then get divorced after just a few months or weeks and then hook up with someone else without blinking an eyelid. We also have gay marriages that are embraced and accepted lifestyles.

Earth is filled with violence Genesis 6:13 Yes, we see that violence is really out of control now, spouses killing each other or parents killing their own children, humans eating the flesh of other humans, other governments shooting and killing their citizens without any remorse, etc.

The times we are living in are not business as usual, but its the perfect description of the days of Noah and Lot, which means its very close . . . we just need to look up and rejoice . . . JESUS IS COMING SOON!
