Getting married is an every day event, just like eating and drinking. There’s nothing in the text that implies the marriages referred to are anything out of the ordinary. In fact, the plainest reading of the text is that marriages are used because, just like eating and drinking, they are such a completely ordinary event.
I’m not saying that it couldn’t be an additional implication, but there is really nothing to lay your finger on that points to that which isn’t more easily explained by a less extraordinary interpretation.
It's certainly not something I would want to argue over but it's still an interesting possibility especially considering the inordinate amount of interest in the occult these days.You can hardly read a magazine or newspaper without seeing a deluge of ads for so-called 'phsycics/mediums' offering guidance and so on.
Having said that I think you're right that the main implication is that man is carrying on as if nothing is happening.Totally blind to what's headed his way.We certainly live in interesting times!
God bless
