Hehe, I have no interest in converting you into anything else. But I do think that traditional/religious Christianity suffers from a limiting paradigm/context that, when put into the proper spiritual perspective, will make perfect sense.
It should be evident that Truth needs no proof. What's there to prove it? It's like trying to prove, "Love is good." Scripture is not an adequate source of proof, due to mistranslations and misinterprations and whatnot. Truth is Truth, no matter who says it or where or when -- usually you can tell it's true, just by common sense. So forgive me for lack of "proof", because I haven't read much of the Bible to give it to you anyway
To understand Christianity it is important to understand the context under which the religion formed. Back in the days of Jesus Christ, most of the world was still uneducated, barbaric, sinful. I was just reading Mark the other day and it talks about Jesus clearing hordes of people of demons (read: lower astral entities) that were possessing them. Wow!
It was impossible for Jesus to explain Divine Truth to uneducated people, so he went by way of parables. Unfortunately, a lot of his words were misinterpreted, mistranslated (he spoke Aramaic, not Greek as it's commonly supposed), and sometimes just plain hard to comprehend, unless you're an enlightened mystic like him too
That's why you get all of these confusing paradoxes that make Christianity so hard to logically grasp, because it really is just a mishmash of man's egoic interpretations, visions, mistranslations, projections, etc. with Divine Truth.
Keep in mind, the Old Testament didn't come from Jesus' mouth at all, but by prophets who often mistook visions of the lower astral realms (hells) for God's Word, same with Revelations in the New Testament. Both of these weren't even included in the original Bible, but were added later at the Council of Niceae in around 430 AD. This mistake was influenced by demons in the astral realms who perceived the pure New Testament as a huge threat to their livelihood, and thus tried to mix in falsehood along with Truth to dilute its power over mankind. Some parts of the Bible were actually taken out, as the Church/Council members deemed them as being too advanced (read: high level of Divine Truth) for lay people to understand, and so based on their own egoic judgment they did not include them.
Jesus Christ was an enlightened mystic, and also a Divine incarnation. It has been muscle tested (Google search for "applied kinesiology" and "David Hawkins", it is as close to Truth as you can get -- or PM me
) that he led only led one life and had no previous lives, and indeed he did descend from the High heavens (read: celestial realms above the higher astral), and his purpose was that of Salvation (read: clearing mankind's karma and guiding them towards heaven, from which it is easier to become fully enlightened than in this purgatorial world, and in which Christ consciousness is able to act as man's intercessor with God/angelic beings).
It's religion that tries to promote itself as the "only" way, the only Truth. And look at how much trouble it's causing between Christianity and Islam. Religion is based on the Church's control over people, and thus a lot of rules, regulations, policies, and teachings in Christianity were actually based on people in the Church trying to control others. If the Church didn't say that "our way is the only way", would you think they'd be nearly as successful? It is only through fear and control that they got so much power in the Middle Ages.
It is true that Jesus did say, "The only way to God is through me" -- but what he meant was the Christ body, above the Buddhic body and below the Atmic body. If you've heard of etheric/astral bodies, the Christ body is just another one in which man eventually spiritually passes through, before full liberation/enlightenment. There are plenty of other quotes that seem to suggest that his Truth is the only Truth, and that is true -- but it must be taken in proper context. If you logically think about it, there can only be one Absolute Truth -- otherwise, it wouldn't be true, right? You can't have two different Absolute Truths. Thus, this is what Jesus meant -- his teachings, at the time and context that he was teaching in, and from his enlightened mystical perspective, and complete with the nonverbal teachings (read: energetic/psychic/spiritual communication on the etheric level, which has been lost), is the Absolute Truth. That is all he meant -- note, he did NOT say that Christianity is the only truth (read: control/manipulation tactics instituted later on by the Church), he said the Absolute Truth that he was teaching is the Absolute Truth, and there is only one. The Truth as directly experienced by a mystic, is completely different than the Truth as interpreted by a man's ego (read: animal instincts, "sin" nature).
This Absolute Truth has been widely known as the "perennial philosophy" which I highly suggest you Google search on. This concept explains why ALL religions are partially right and partially wrong -- they all describe the one Absolute Truth as best as they can, but due to human limitations of interpretation and language and the ravages of time, their accuracy has been highly diluted. That is why all religions share so many commonalities, because they're all describing the same thing, just in different words! Note how it is only religion that says "my way is the only way" (which separates men and cannot be what God wants), and not spirituality (which unites all men in all religions together in harmony).
Anyway, from all of the above, it should be clear that:
1) Christianity most definitely is NOT the only way
It is a good and common path to tread, and indeed Christ Consciousness is there to intercede for you in heaven, but other paths to God are valid as well.
2) From 1) we can see that there is no need to worry about people who have not discovered Christianity, they have discovered other paths to God and are thus saved. There are other angelic beings in the celestial realms who help those with lower levels of consciousness, not just Christ Consciousness, so no need to worry. And they, for one, don't care about what religion you believe in on Earth -- all they care about is your spiritual integrity (read: level of consciousness).
