This does not resolve the issue at all. I am not a witness, neither is anyone on this planet now. We are still relying on the witness testimonies of other fallible men...
...I'm not really sure how you expect me to run tests on any of the above. In addition I am not sure how this deals with error prone messengers.
Quite simply I think that you come across as the type of person who requires a detailed study before you could make a decision one way or the other. Perhaps you may have heard some classic examples of these types of people like the lawyer John Warwick Montgomery, or the archaeologist William Ramsay, etc. William Ramsay said that after years of investigation he has come to believe that Luke is a historian of the 1st rank...now for a lot of Christians that means a lot, but for other people it means very little. Some people simply need their own scale of measurement, period. Meaning that their mentality is 'Until I personally comprehend WHY Luke is a 1st rank historian I can absolutely care less who 'Says' that he is!' I'm not claiming that the Christians who are willing to take Ramsay's word for it are lazy, or gullible. The reasons that they are not is because the large majority of Christians only need a little bit of intellectual nudging because it is a fact that there are some very powerful experiences that go on inside of a Christian (a God experience if you will) that has way more weight to them than technical reasoning. But having said that that does not cut it for a minority group of people who come to be Christians.
I simply don't think that there is a short cut for some people. Sometimes it makes me shake my head at how many things William Lane Craig knows, and I listened to so many of his debates (and was still undecided for years). One day I realized that I was going to remain in the 'Not sure' zone for life unless I did one of 2 things, dump the whole issue of the Bible altogether, or stop just listening to the surface level debates and dive into a much deeper study for a more informed decision.
Why not just send the message directly to hearer. What purpose does the fallible intermediary serve?
This freaked me out for years. As much as people want to debate how CLEAR the truth of the Bible is IMO it can be ambiguous, one week the reasons that I believed the Bible was true would dominate me, the next week the reasons that made me think it was all just coincidence would dominate me. And back & forth I went for years. Angry! Screaming at God at times how annoying it is, that if he simply struck me with better proof I would be a full blown Christian!! But, I was no Christian at all, it was all just an academic curiosity to me. The idea of God, and the idea of the ultimate meaning of life just intrigued me for years intellectually. Finally, and this is the part where I think I am very unique, my bluff was called and I seemed to get answers that I was looking for for years and I found that I was convinced (the answers that bothered ME at least, everyone is different in what objections bother them).
Well, there were no fireworks...it was kind of just like a 'Huh' reaction. I laugh because I compare it to the Seinfeld episode where the doctor told George his fiance was dead and his reaction was just 'Huh.' It was really just that, a 'How about that I think it's true' reaction. But...i didn't like Christianity as it turned out. Now logically the next step was to BE a Christian and I actually became miserable for a long time. When I say that I was very unique I mean, who believes the Bible but hates it?? I really did simply hate the idea of it being true. This time period was when I realized that Christianity can be boiled down to one basic question 'Would you want to live in a world where Jesus is the king of that world, yes or no?' And I could honestly say that I didn't.
There is a famous saying that goes something like 'There is enough light for those who want to believe, and enough obscurity for those who don't want to believe.' Well I literally was living proof of why that is true (at least I think based on my experience), I was completely miserable that I had this new belief that it was true (yet I hated the belief, as I said it was all just academic for me). I DID NOT want to live in a world where Jesus was king, I'd rather keep drinking, keep my crude ways, and I by no means wanted God to be some focal meditation point of my life. So I do get the obscurity in one sense. I actually lived out the answer to why CLEARER proof that the Bible is true might not be given, because clearer evidence might cause millions to be totally miserable with that knowledge (like I was).
But having said all that, my time was spent almost entirely outside of the Bible. 95% of my focus was critical analysis on whether or not the Bible was true with little regard to actually reading it for the sake of reading it. My attitude was 'Yeah yeah I get it, Jesus is born, gathers his apostles, starts his ministry...crucified, etc. I know the basic frame work no need to re-read anything.' For the most part I enjoyed arguing with atheists lol. And when I did read the Bible it was always with an attitude of challenging doubt, stopping every other paragraph to say 'Yeah right!' Well it turned out that there was a strange phenomenon that would occur when I suspended my antagonistic attitude and just read the Bible in an attitude of acceptance. I became overwhelmed with weird feelings that it was true. This definitely went beyond a psychological mind over matter, this was unique, because there were definitely other books that I could read (that I didn't believe) with a suspended antagonistic attitude yet not have even close to the feeling I got when I read the Bible with the same attitude. But there was another unique feeling too, at times these unexplainable tweaks occurred inside me that effected my outlook on what I considered pleasurable and what I considered overrated. Meditating on Jesus, that which made me roll me eyes, actually started feeling like an intense natural high...whereas things like getting drunk still had an appeal, yet is would feel like much less of an urge than before. Things that were underrated to me started becoming overrated, and vise versa.
I always used to cringe at what I referred to as 'Bible thumper' phrases because I considered them to just be hot air, and one of those phrases that always annoyed me was 'Spiritually discerned.' Well I started realizing that the strange reactions and feeling tweaks inside me that were happening as I read the Bible often was this thing called spiritually discerned. Because I knew what 'Discerned' meant. And I knew that I was going into these reading sessions in a state of doubt (or indifference)...yet I was coming out of them in a state of increased belief?? Yet I knew that I was picking up no new information that I had not already known. This made zero intellectual sense to me, but strangely it was happening. I was reading gospels of which I already knew the details, and as I said before there were other books I could read that never had this effect on me. Another 'Annoying Bible thumper' term started to entire my mind...Daily Bread. Wow was this actually true that you need daily bread, and that the Bible could be actually be discerned in a different way than intellectual discernment?? Apparently so for me.
It was a weird revelation indeed. Perhaps I wasted years refusing to read the Bible openly and just focusing on intellectual discernment. Perhaps if I did both I'd of saved myself a lot of time. I didn't want to admit to another 'Thumper' phrase but I also started to realize the truth behind the verse 'Draw nearer to God and he will draw nearer to you.' Clearly I wasn't drawing nearer to God when I thought about God like a math equation, nor was I drawing nearer to him when I read the Bible with an attitude of 'Yeah right, whatever.' But going way back to the beginning, there were always these rare occasions in my life where I would very intensely pray to Jesus to have him open my eyes. I see a lot of people in these forums who seem like they opened a similar Pandora's Box as I did (by the way they post). I am absolutely convinced that I was a case of be careful what you wish for you might get it. I think I prayed Jesus into my life and afterwards I was never able to toss him aside with a total clear conscience ever again. There were indeed many many time I tossed him aside, and sooner or later I would get these strange impulses that something was missing. Well before ever going thru with any of those intense prayers those strange impulses never occurred in me. I really do think I prayed him into my life and was never able to go back.
So anyway, might wanna try to hit it from both ends, go deeper in your intellectual study, but also suspend your disbelief and read the Bible with an attitude of acceptance and see if you experience that feeling of spiritual discernment. And if you do good luck trying to explain it to people I've tried for years, it's totally an experience. I suppose it's like trying to explain to someone what it's like to skydive.
