The time leading the world into the
Tribulation is called the "beginning
of sorrows".

"For nation shall rise against nation,
and kingdom against kingdom: and
there shall be famines, and pestilences,
and earthquakes, in divers places.
All these are the beginning of sorrows."
Matt. 24: 7-8

The Day of Grace will be over.

Right now we have racial warfare:
Nation shall rise against nation:

Political warfare:
Kingdom against kingdom;

Famines, and pestilences and earth-
quakes; but all these things will stay
in the world....

but when they start to occur
all at the same time, it is a sign that
we are moving toward the days of the
Tribulation.
