I also related in spiritual terms when I watched his interview. One of the 4 preconditions was a type of despair over the meaninglessness of ones life. It's hard to see a Christian having this problem since the way gives us meaning. But for those that don't know the Lord, I would think it would be like the "stones of emptiness" spoken in scripture. Then there's the idea of God bringing delusion on those that reject the love of the truth, etc... What would that kind of mass delusion look like? Probably like the one Desmet is describing (imo)
Paul had a lot to say about delusion.
2 Thessalonians 2:8-12 For the mystery of iniquity doth already work: only he who now letteth will let, until he be taken out of the way. And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming: Even him, whose coming is after the working of Satan with all power and signs and lying wonders, And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved. And for this cause God shall send them strong delusion, that they should believe a lie: That they all might be damned who believed not the truth, but had pleasure in unrighteousness.
Who is the liar? John explains.
John 8:44 Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.
If Satan is the father of lies, then we have to go back to the very first lie ever told to see what the lie is.
Genesis 3:4 And the serpent said unto the woman, Ye shall not surely die.
In this one act, he became the father of lies, and a murderer from the beginning, because the wages of sin is death (Romans 6:23).
The lie perpetuates through sin. Take a look at Revelation 22.
Revelation 22:14-15 Blessed are they that do his commandments, that they may have right to the tree of life, and may enter in through the gates into the city. For without are dogs, and sorcerers, and whoremongers, and murderers, and idolaters, and whosoever loveth and maketh a lie.
Paul goes into detail about who God sends delusion to in Romans 1.
Romans 1:20-32
20 For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse: Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened.
21-22 Professing themselves to be wise, they became fools, And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things.
24-25 Wherefore God also gave them up to uncleanness through the lusts of their own hearts, to dishonour their own bodies between themselves: Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator, who is blessed for ever. Amen.
26-27 For this cause God gave them up unto vile affections: for even their women did change the natural use into that which is against nature: And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly, and receiving in themselves that recompence of their error which was meet.
28-32 And even as they did not like to retain God in their knowledge, God gave them over to a reprobate mind, to do those things which are not convenient; Being filled with all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, debate, deceit, malignity; whisperers, Backbiters, haters of God, despiteful, proud, boasters, inventors of evil things, disobedient to parents, Without understanding, covenantbreakers, without natural affection, implacable, unmerciful: Who knowing the judgment of God, that they which commit such things are worthy of death, not only do the same, but have pleasure in them that do them.
How does the above tie in with Mass Formation Psychosis and Moral Decay?
If Satan is the father of lies, it stands to reason that he is behind the perpetual spreading of lies that deceive the whole world. This would also mean that he is responsible for long-term deception—indoctrination, predictive programming, moral decay—you name it.
The original lie from which all other lies proceed is that there is no consequence for disobedience of God. I don't think of it as mass psychosis at all, because it's not some fluke, not some mental illness, it's the result of sin and the ongoing satanic agenda that will not end until the second coming.
