Why do I believe in the UB? It explains things in a way that I find more believable.
God does not interfere in natural events nor does He interfere with free will.
Lucifer was not created by God to tempt humans. Angels are given free will and Lucifer rebelled against Jesus, not God.
The devil attempted to secede the earth from Jesus control during the Lucifer Rebellion. He is not the same being as Lucifer and he was not created to tempt you.
Evolution is true but angels started it and God causes the evolutionary events to happen.
Every stable life form is built in to DNA. Humanity did not come from a series of random mutations.
Adam and Eve were not the first humans. They were angels who were supposed to have children on the earth that would eventually mate with humans enabling humans to evolve much more quickly.
I could go on but by far the main thing is that God is not an angry and jealous God. How could the Creator of the universe be jealous of anything He created?
I understand. When I first heard of Gnostic theology, this also made much more sense to me than Christian doctrine. The Quran makes more sense to some who then decide to convert to Islam. Then there's the Book of Mormon which other folks find sensible.
Some parts of it may support your own experiences. Parts of it may even be validated, like historical parts of the Bible. Doesn't mean you have to accept any parts of it which you can't verify.
A good narrative will use facts, validated historical evidence to make it more believable.
If I was going to create a book on metaphysical truth, that's exactly what I would do. I'd take my visions, dreams, inspirations provide reasonable interpretations and conclusions and intersperse it with verifiable facts historical evidence/documents. First hand accounts all in support of this narrative of truth. 100% intention on my part to provide beneficial information to my fellow man.
Would I have anything other than my visions, inspirations to base this on? Not really.
You have to judge for yourself what belief/set of beliefs is best for you to rely on. Personally, I was never satisfied with a good, convincing narrative. They are not really that difficult to create. It's a type of sophistry that sometimes even the narrator has convinced himself of its truth. In fact, conviction in one's own narrative folks find very convincing.
Believe what you feel is correct to believe but reserve any real conviction until you are able to verify every part of it is my position.
In any of my beliefs, I am ready to be shown I am 100% wrong but that requires proof and validation.
If you are just relating the truth according to the UB, fine. Anyone choose to accept the claims of the UB for what it's worth. You seem to be posting from a position of certainty about what it claims to be true however and you're not really.
You're speaking from the position of accepting a convincing narrative like any of the folks from any other of these various religions.
