In the philosophy, the idea of a man being the God dominated end of 19th century , many years after the enlightenment revolution.
Nietzsche "killed the God" and after him, so many have done it.
Consequence of that murder experienced billions of people in 20th century and nowadays.
In I recognition, man who believes that is a God (God for him-self, no master above him) is cursed by satanic illusion and thats looks to I very luciferian. The bad wants his victim to believe it, then the person is very easy to manipulate and is loosing the contact with its spirit ( I ), it is the worst curs that can happened to a man and is often happened on the person own wish (own believe that it is true that there is no God).
Evil is giving then powers that are unusual to ordinary people, first is the self confidence (in extreme - megalomania), another can be believing in forecasting of the future events - more like some material and intellectual powers, wishes and needs of spiritually poisoned person can be easily fulfilled - that is the kind of power that was promised to Christ when He was under temptation during His fast.
The energy that is used to fulfill the wishes is taken from the spiritual fire of the person, what can finished with serious physical sickens, mental disorder or even death/suicide. Usually, potential victims are unusual personalities, especially people who has high intellectual and spiritual potential as they may lead others on the same path.
What I can advise to the I?
Be very, very careful in contacts with that man, from that what I see now, the I is already under influence of that man ( the confusion that the men caused to the I are proof of that, the I is right in believe and is The Mighty who warn the I about the man).
If the I will try to influence this man then the I will see what is going to happened, he will try to manipulate the I - Danger!!!
If its the I friend that can be so hard to the I and even more dangerous.
What I would do if I were in position of the I, I would pray for that person, so Jah could take away the influence of the bad from that man as well try to stand away for sometime from that man and see what is happened with what is he doing.
Sometime it may looks like it is great work what that person does, but it may be illusion, some plants has beautiful flowers but it doesn't means they will bring healthy fruits as it is a long way and so many things can happened.
I don't know the I spiritual strength, but there is not so many people who can deal with those matters.
This, what is that man believing in, is big illusion
and betray to Almighty.
It is against the First Commandment.
If the situation is close to what I described, that man is in danger and is danger to others too.
Jah Save I&I
Blessings in the name of Almighty
