The message is, that things CAN change in HUGE ways, k’heref ayin (in the blink of an eye).
Does it mean Mashiach is coming tomorrow?
Maybe.
But the point is, it COULD be.
And if it’s not tomorrow, it could well be the day after, or next week or next month, but certainly SOON.
So… the message is: Are you really ready for that day?!?
