After the Sign of God manifests, the veil will be removed from the Second Heaven (only). Beings that reside in the Second Heaven will become visible to all for the first time in our age, including the evil or Dark Hat ETs and the good or White Hat ETs.
Believers in the Beast System will become pitted against believers in the One True God of the Holy Bible.
Cities of Light will emerge, and commerce with the White Hat ETs will take place. For Southern California, that will be Downtown Los Angeles (DTLA), with the SW quadrant being used for commerce.
It will be hard to resist all the allurements of the Dark Hat ETs. It will be like the movie Pinocchio, and once a person signs allegiance to the Beast System, they will forever be lost —soon in body, forever in soul.
9 And the third angel followed them, saying with a loud voice, If any man worship the beast and his image, and receive his mark in his forehead, or in his hand,
10 The same shall drink of the wine of the wrath of God, which is poured out without mixture into the cup of his indignation; and he shall be tormented with fire and brimstone in the presence of the holy angels, and in the presence of the Lamb:
11 And the smoke of their torment ascendeth up for ever and ever: and they have no rest day nor night, who worship the beast and his image, and whosoever receiveth the mark of his name. (Revelation 14:9–11)
The enemy has always had technology. That is why this outcome has always been known, except by us who will live through it. Now, on its cusp, we see how it will be fulfilled.
