Lunar, Hebrew and Catholic calendars, and mankind's propensity
It's expected that with the grace period of the Son-of-God ended in 2027, world leaders will go mad with power and begin to destroy each other and all getting in their way.
* The biblical number 7 is not necessarily counted as an actual full amount of anything, but is an approximation. Therefore the prophesied seven years of disaster leading up to Armageddon are relative.
As of writing, we note the worldwide honey bees are dying off. Gold will be valueless and gunholders will find all their bullets inert. This is a highly-orchestrated, scientifically devised global disaster. There will be no one to turn to except for God's Deliverer, the "Son" of-God.
"Mene Mene Tekel U'Parsin"
When ancient Babylon was warned by the handwriting on the wall that it's days were at an end, the terminology Daniel interpreted was of they being weighed and and caught wanting in the balance --Mene Mene Tekel U'Parsin -- of where a 50 shekel weight (mina), plus another 50 shekel weight (another mina), plus a single shekel (tekel), plus a half-shekel (u'Parsin, to mean, 'and a half') only added up to 2.520 gerahs - their smallest monetary units.
Our not knowing how items were valued in those days, it was obvious—at least to Daniel—that Babylon had failed in it's accounting, so God was going to take Babylon's prominence away for 2,520 years. The Medes and Persians conquered Babylon that very night, and Nebuchadnezzer lost his mind , and grazed on grass.
The prophecy seemingly quite esoteric, it turns out that the period of 2,520 years from that fateful night ostensibly ended in our modern year of 1968 AD (the date adjusted owing to poor record keeping). Therefore all set in place before that year was merely preparation for the evil of Babylon to reassert itself, which it has done in these, our last days. Their aim is complete and utter worldwide control.
Now, the reason that God will stop Armageddon is due to the killing of Tzadikim Nistarim, the Hidden, or Secret, Righteous men of the earth upon which the Babylonian Talmud asserts that God relies upon, to justify the world's right to exist. Armageddon is the New World Order's plan to rid earth of overpopulation so it can rule without contest. God will destroy the world when The Order kills one or more of God's Tzadikim Nistarim (said to be 36 in total).
