Early Friday morning July 28, 2017 is 738,000 days (= 2050 times 360, or 41 times 18,000) since The Annunciation and 41 years previously, was the deadliest earthquake in four centuries, the Tangshan China earthquake at 3:43 a.m. local time July 28, 1876.

The archangel Gabriel visited Mary on Monday 1 January 4 BC (Julian...Monday 30 December 5 BC Gregorian) and Jesus was probably conceived three or so days later, then born 267 days after that, on Friday night September 26-27, 4 BC.

The archangel Uriel, a.k.a. John the Baptist, allegedly visited an American man after midnight Monday January 6, 1930 and delivered a message about how World War would "rage again" and God would bless his people with "Greater light and power" at some time in the future.

The Book of Joel and Book of Micah and Book of Daniel sound a similar theme: Amidst a time of war or other distress, God would "pour out his Spirit" on a waiting remnant who would then go forth as missionaries and healers.

That "Eighteenth Message" to Otto Fetting Monday January 6, 1930 happens to be 41 times 41 times 420 days after Monday 1 January 4 BC....and January 6, 1930 in turn is three times 41 times 260 days before July 28, 2017....that's amazing!

Clues as to what may happen on this coming Friday July 28 I believe can be found in the message the angel gave on Monday January 1, 4 BC and the message an angel gave on January 6, 1930.

I want to have another look at that catastrophic earthquake to hit China July 28, 1976, that day happens to be the same in the 260-day

cycle as Thursday 21 October 521 BC, when God reportedly said to Haggai:

"This is what the LORD Almighty says: 'In a little while I will once more shake the heavens and the earth, the sea and the dry land...I will shake all nations, and what is desired by all nations will come, and I will fill this house with glory..."

Spiritualizing that prophecy, or interpreting it in modern terms, it probably means God will cause relationships to take place, and bless those relationships to the mental and physical healing of participants, to where those so blessed are then a blessing to a widening circle of others...

Another "sign" about what may happen this Friday is a couple of other things that happened on July 28 in history:

July 28, 1914:

1914 – In the culmination of the July Crisis, Austria-Hungary declares war on Serbia, igniting World War I.
https://en.m.wikipedia.org/wiki/July_Crisis
"At 11:00 a.m. on 28 July, Austria declared war on Serbia.[129] Following instructions from Bethmann Hollweg, von Tschirschky did not present Wilhelm’s "Stop in Belgrade" proposal until noon.[129] At 1:00am on 29 July 1914 the first shots of the First World War were fired by the Austrian monitor SMS Bodrog, which bombarded Belgrade in response to Serbian sappers blowing up the railway bridge over the river Sava which linked the two countries.[153] In Russia, partial mobilization was ordered for the four military districts bordering Austria-Hungary..."

And another thing that happened on July 28, 1945...check out the image of the Empire State Building in flames:

Now, a "pillar of smoke [and fire]" is symbolism for a heavenly, "Pentecostal" endowment, this is what St. Peter meant by mentioning that at the first Christian Pentecost Sunday May 18, 31 A.D. ( and I believe that is why Mt. St. Helens volcano erupted on Sunday May 18, 1980)
https://en.m.wikipedia.org/wiki/1980_eruption_of_Mount_St._Helens

In short I believe Friday 28 July 2017 is a day of "endowment from on high" whether or not there's a war that breaks out that day. I think I can safely predict that if You wait for it, it will come, some kind of evidence in your own life that God and angels are involved in your welfare and the development (creation) of yourself as a more and more advanced human being.
