In Revelation 9:15, it states that these angels
"were prepared for an hour, and a day, and
a month, and a year, to slay the third part of
men"

This must mean that the loosing of these
angels which had been imprisoned has been
set for a certain time, and this event will ful-
fill a definite purpose in God's plan.
Acts 15:18 "Known unto God are all his works
from the beginning of the world."

God never has to ad lib, but he knows the end
from the beginning, He has expected every
detail.

Every detail of the prophetic word will move
on to the appointed conclusion of His plan.
