Jesus gives us many characteristics of this
awful period of time known as the 'Great
Tribulation Period'. A large portion of the
book of Revelation is about the Tribulation.


"And the kings of the earth, and the great
men, and the rich men, and the chief
captains, and the mighty men, and every
bondman, and every free man, hid them
selves in the dens and in the rocks of the
mountains;

And said to the mountains and rocks, Fall
on us, and hide us from the face of him
that sitteth on the throne, and from the
wrath of the Lamb:

For the great day of his wrath is come; and
who shall be able to stand?"
Revelation 6:15-17
