I like your post (and totally agree with the first paragraph), but have some concerns that are a little different from Bugmaster's.

What's the exact difference between a god and a demon? Suppose Wicca is run by a supernatural being (let's call her Astarte) who asks her followers to follow commendable moral rules, grants their petitions when expressed in the ritualistic form of spells, and insists she will reward the righteous and punishes the wicked. You worship a different supernatural being who also asks His followers to follow commendable moral rules, grants their petitions when expressed in the ritualistic form of prayer, and insists He will reward the righteous and punish the wicked. If both Jehovah and Astarte exist and act similarly, why name one "a god" and the other "a demon"? Really, the only asymmetry seems to be that Jehovah tries to inflict eternal torture on people who prefer Astarte, where Astarte has made no such threats among people who prefer Jehovah, which is honestly advantage Astarte. So why not just say "Of all the supernatural beings out there, some people prefer this one and other people prefer that one"?

I mean, one obvious answer is certainly to list the ways Jehovah is superior to Astarte - the one created the Universe, the other merely lives in it; the one is all-powerful, the other merely has some magic; the one is wise and compassionate, the other evil and twisted. But all of these are Jehovah's assertions. One imagines Astarte makes different assertions to her followers. The question is whose claims to believe.

Jehovah has a record of making claims which seem to contradict the evidence from other sources - the seven-day creation story, for example. And He has a history of doing things which, when assessed independently of their divine origin, we would consider immoral - the Massacre of the Firstborn in Exodus, or sanctioning the rape, enslavement, infanticide, and genocide of the Canaanites. So it doesn't seem obvious at all that we should trust His word over Astarte's, especially since you seem to think that Astarte's main testable claim - that she does magic for her followers - is true.

Now, you've already said that you believe in Christianity because of direct personal revelation - a sense of serenity and rightness when you hear its doctrines, and a sense of repulsion from competing religions, and that this worked even when you didn't know what religion you were encountering and so could not bias the result. I upvoted you when you first posted this because I agree that such feelings could provide some support for religious belief. But that was before you said you believed in competing supernatural beings. Surely you realize how difficult a situation that puts you in?

Giving someone a weak feeling of serenity or repulsion is, as miracles go, not a very flashy one. One imagines it would take only simple magic, and should be well within the repertoire of even a minor demon or spirit. And you agree that Astarte performs minor miracles of the same caliber all the time to try to convince her own worshippers. So all that your feelings indicate is that some supernatural being is trying to push you toward Christianity. If you already believe that there are multiple factions of supernatural beings, some of whom push true religions and others of whom push false ones, then noticing that some supernatural being is trying to push you toward Christianity provides zero extra evidence that Christianity is true.

Why should you trust the supernatural beings who have taken an interest in your case, as opposed to the supernatural beings apparently from a different faction who caused the seemingly miraculous revelations in this person and this person's lives?
