When I was a Christian, I was told that Joseph Smith, Muhammad (FBUH), and the like were in communication with the devil when they concocted their false religions. Alien abductees were actually victims of demonic encounters.
So Satan has the ability to create false religions, he has the desire to, and he has in fact succeeded in doing so.
Now, imagine that you're Satan in 1000 BC. You see that God has established a covenant with man and has set up specific rules for living, atonement of sins, and etc. You want to deceive these people. How do you do it?
Would you perhaps find a way to convince them that they don't need to perform animal sacrifices? Would you find a way to convince them that the temple is no longer a holy place? What if you could accomplish this by substituting for God someone else that they could worship? Would that be a worthwhile aim, again, pretending that you're Satan?
If you're Satan in 1000 BC, what parts of the New Testament would not seem like a good idea to you? In short, I'd like to know what parts of the New Testament could not have been authored or inspired by Satan. What parts of the New Testament contradict Satan's goals to the point that he would not advocate such ideas even to advance a false god for people to worship?
If you refuse to answer this, then you surrender your right to fling accusations of other religions or experiences being Satanic. And worse, if you refuse to answer, you have absolutely no way of knowing whether or not your beliefs are an extreme insult to YHWH.
The resurrection of Christ is a very large issue that is against Satan. Mages, witches and occultologists have spent thousand of years trying to master resurrection/eternal life. All have failed, and have at best only replicated simulated resurrection -
necromancy. Resurrection proves God-like characteristics in man (since Christ is a man,) and therefore would also show the satans to be a liar from the garden.
"Eating the fruit of the tree of knowledge of good and evil" would not cause Adam and Eve to be like gods;
they were already gods. Duality - confusion, not unity is what devolved the human race from sons of God to sons of carnal man.
Another is the genealogy of Christ, and therefore the genealogy of Cain, and thus the apparent splitting of bloodlines - one of son of Man, and one of enmity with the seed of the serpent.
A third would be the twisting of words of Christ by asserting Christ only wants us to follow law of love - without acknowledging that that means following the word of God - including His laws. Over and over again in the NT, we are told to follow the word of God, to be obedient as this is pleasing to Him. We are also told faith without works is dead.
The enemy (satans) do not need to decimate the truth; they have been around humanity since the beginning, so they understand Truth cannot be destroyed. It is sufficient to build dialectics, and paradigms based on twisting of words. This was the same tactic used in the garden, and it still works. Why fix something that isn't broken?
Another is to squelch the idea that there are, in fact, interdimensional beings that not only polluted the genetics of the human race, but they also
continue to have contact with humanity.
There are a plethora of things that have been canonized, which are twisted cultural and religious alignments to strange doctrine and false teaching. It only takes a little bit of "leaven" to pollute something.
One of the major disadvantages the West has is that they do not believe in the spiritual world much, if at all. (This is especially ironic considering Western Christians do believe that Christ resurrected, and that He cast out
demons, and raised the dead.) That severely handicaps those Christians who don't realize there is spiritual warfare. Everything else is consequentially in favor of the enemy from that lack of understanding. Most people East of Jeruselum know and understand there exists a spiritual world, and have no problem believing/accepting that it is real - especially through experience. The West has set up a cultural and psychological paradigm so that even if Eastern religions have something to offer, they will likely be rejected due to "9/11," the Taliban, Osama bin Laden, and so on.
And, a culture of scoffing, anger, disillusion with religion and charlatans, and so on also greatly keep people from their God-given glory and status.
The point of the principalities, angels, powers, and archons is to get all of us to
want to reject God, His legal covenant agreement between us, and the fact that HE exists. It isn't that convoluted. These entities have the added bonus of working with egotistical creatures that can confuse even the smallest changes in detail.
We have a mathematically chaotic psychology that we believe is normal, and natural. It makes us easy spiritual game.
