Yes, you are on the right track. The bible and the gospel were written to the Jew first, then the Gentile, so a complete teaching of Mystery Babylon needs to include identifying Jerusalem as "that great city" that persecuted the prophets and saints. Why?...because things concerning Israel happened unto them as an example and warning to the church, as scripture says elsewhere.
Mat 23:28-38
Even so ye also outwardly appear righteous unto men, but within ye are full of hypocrisy and iniquity.
Woe unto you, scribes and Pharisees, hypocrites! because ye build the tombs of the prophets, and garnish the sepulchres of the righteous,
And say, If we had been in the days of our fathers, we would not have been partakers with them in the blood of the prophets.
Wherefore ye be witnesses unto yourselves, that ye are the children of them which killed the prophets.
Fill ye up then the measure of your fathers.
Ye serpents, ye generation of vipers, how can ye escape the damnation of hell?
Wherefore, behold, I send unto you prophets, and wise men, and scribes: and some of them ye shall kill and crucify; and some of them shall ye scourge in your synagogues, and persecute them from city to city:
That upon you may come all the righteous blood shed upon the earth, from the blood of righteous Abel unto the blood of Zacharias son of Barachias, whom ye slew between the temple and the altar.
Verily I say unto you, All these things shall come upon this generation.
O Jerusalem, Jerusalem, thou that killest the prophets, and stonest them which are sent unto thee, how often would I have gathered thy children together, even as a hen gathereth her chickens under her wings, and ye would not!
Behold, your house is left unto you desolate.
Rev 17:6
And I saw the woman drunken with the blood of the saints, and with the blood of the martyrs of Jesus: and when I saw her, I wondered with great admiration.
Rev 18:24
And in her was found the blood of prophets, and of saints, and of all that were slain upon the earth.
Rev 19:2
For true and righteous are his judgments: for he hath judged the great whore, which did corrupt the earth with her fornication, and hath avenged the blood of his servants at her hand.
Rev 18:4-5
And I heard another voice from heaven, saying, Come out of her, my people, that ye be not partakers of her sins, and that ye receive not of her plagues.
For her sins have reached unto heaven, and God hath remembered her iniquities.
So the point at which the Lord starts to separate the wheat from the tares (and sheep from goats) in order to judge the tares and goats without harming the wheat and sheep, I believe is the point at which the sins and transgressions of "Babylon" start to ripen and come to the full….when they start to reach unto heaven (like the tower of Babel). Part of judgment includes being given over to deception/delusion, so that is why the true sheep need to get out of Dodge in order not to be caught up in the deception that God sends and other judgments that proceed from it.
The unsealing of the book of Daniel, of which only the Lamb of God was worthy to unseal........meant the fulfillment of those prophecies regarding "Babylon".....transgression come to the full and wrath poured out. The Lamb of God was and is the only one worthy to judge....the wrath of the Lamb.
Mystery .
Mystery of inquity and he who letteth is letting it big time . IT is running its course to the full now .
Christendom in large has rejected the heavenly and now builds only in the earthen kingdom .
establishing an eartly religoin and strange temple with diverse stones and untempered morter .
and many now are co helpers in that kingdom and in its tower . a tower of inclusive love
a tower made of men and its stones are the peoples it has gathered to be as one .
Its morter is the words and precepts of men . IT WILL NOT STAND on the DAY OF THE LORD
and it will never reach to heaven .
Come to they cry and enter into our covenant of inclusive love
come and drink of our waters and eat of our bread . For stolen bread is so sweet indeed to the taste .
But the bread cometh not OF GOD , NOT OF THE LAMB
and all who eat of it will vomit and lose their sweet words .
And they build it all in vain . It is the work of men gone wrong whose desire was always and is always
to be exalted as GOD . On the day of the LORD its all coming down .
IT will not be able to weather the STORM of the wrath OF ALL MIGHTY GOD and of the LAMB .
For they who build in it have rejected the love of the truth , THE GOSPEL OF JESUS
and have believed a lie . YES , A VERY STRONG delusion has been sent , AND ITS BEEN SENT to UNIFY
as ONE THE PEOPLES of this earthen kingdom .
BUT UNTO WHO and what . IT WILL FALL , CRASH and BURN on the day of the LORD
and the utopain peace n safety they all thought the inclusive we are one love lie was to bring
THEY WILL NEVER ATTAIN .
For when they shall say PEACE N SAFETY , i tell us all , SUDDEN DESTRUCTION IS ALL they shall recieve .
We really need to get the people back in the bible so as they can actually learn
WHAT THE TRUE GOSPEL IS ALL ABOUT and that folks will flee this other gospel , WHICH AINT NO GOSPEL
and fast . cause it wont be saving a one of them. no matter how many hands join in hand
THERE WILL BE NO PEACE UNTO THE WICKED . who rejected the love of the truth wherby they could have BEEN saved
and preached a delusion of a love that will damn them all . ITS THAT SERIOUS sister . THAt SERIOUS .
