Maybe read the Gospel of John (4th book in the New Testament) if you want to know the details. It's pretty short, you could easily do it in one sitting. If you don't want to know the details that's your business of course, but be aware that the story you relayed is not Christianity.
I'll just assume it was my pronouns that got ya on this one. God is Jesus. God is God (or Father God, or Allah, or I Am, or whatever your preferred term for the overbeing is) "he(God) is both himself (Father God) and his son (Jesus)"
It's exactly what I said above.
It's a bit arrogant, given a book which alleges to reveal divine secrets of reality, to assume said book should all be perfectly intuitive and easy to understand. "Sacred Hidden Truths for Dummies"? :)
And at face value, it appears to be a pretty lame patch on an appearance of paganism (multiple gods, oh wait, its really one).
You could take a practical book about how to survive on a desert island. But, since you're gonna live forever, everything in there is stuff you could figure out on your own eventually. So this book's value is only short-term.
You could take a new age book with lots of feel-good, intuitively-pleasing platitudes. But, again, you could just invent all that by yourself. Probability of eternal-term value: 0.
A collection of stories like the ones in question at least has some chance of providing eternal-term value, precisely BECAUSE on the short-term they seem so absurd. If they were intuitively pleasing at first glance, then you could just come up with them yourself eventually. This same reasoning would apply to any similar collection of stories, but the stories in question at least have a lot of precedent / test-of-time / reputable endorsements.
God loves you. Why hide the keys?
If a higher power would try to teach me some lessons, I assume (by analogy) that those lessons would similarly come in the form of stories or parables etc. Just like my daughter understands my teachings better in that form, I assume I would understand a higher power's teachings better in that form.
If a book claims to be inspired by a higher power, and I read it and everything looks immediately feel-good intuitive/logical on the surface, than I'm going to reject it, saying: "I could have written that myself!"
I think the pride comes in assuming that the being that created the book is exactly like yourself. That assumption is egocentric.
That the nature of the being who created this universe is complex, and isn't exactly like us, shouldn't be that surprising. Any being capable of such things would surely be different from us in some material way. When that being describes himself, and those descriptions do not line up with our expectations, thats ok. He doesn't exist inside the confines of the universe he created and that we live in, and is not bounded by it or its rules.
The gospel isn't, on the whole, that complicated. All mankind are sinners. The consequence of sin is death. The way to be saved from death is to accept a divine gift. To accept the gift, you need to acknowledge your sin, accept that the giver exists and that the gift exists, and ask for it. There are further details and surprising depth and beauty, but the basics are very simple.
I don't think He hid the keys.
The Christian belief of the Trinity is readily admitted by Christians to be mind-boggling. We do not therefore consider it false.
https://en.wikipedia.org/wiki/Wave%E2%80%93particle_duality is also a "logical nightmare". If the Creator of such phenomena Himself fit neatly into our logical boxes, wouldn't that smell like fabrication?
There is no analogue to this in christianity. You just have to accept it as mysterious, and then you claim that if there weren't such mysteries, it would seem fake. That's a rationalization. There is no logical reason for there needing to be mysteries to god. You need there to be one because in the reality of your beliefs there are mysteries.
What you've described is called "modalism" (aka "Sabellianism", after a guy named Sabellius) and is taught against in Scripture and rejected by the Church under all non-cultish denominational flags. The doctrine of the Trinity is difficult to "wrap your arms around" but very easy to state:
1. The Father is God.
2. The Son is God.
3. The Holy Spirit is God.
4. The Father is not the Son.
5. The Son is not the Holy Spirit.
6. The Holy Spirit is not the Father.
7. There is one God.
From this the language of the Trinity (1 being, God, who consists of 3 persons, the Father, Son, and Spirit) was developed by the Church to describe what is taught in Scripture.
