Christain's as a whole mean well, I do believe they generally do want peace and "souls saved",
and perhaps some miracles did happen, strange things do in this world.
What I DONT understand is they already know that Mathew, Mark, Luke and John were at best followers of Jesus - writing what they recall he did etc 20 years after his death.
Even with an intention to be as accurate as possible, their recall will change due to their perspective of interpretation, what they write will change due to their intention.
If christianity believed the views of JC were effectively that of god ... the dead sea scrolls (reputably written by JC himself without others putting their lean on it) is probably a safer bet.
Proving it was JC that wrote them, not so easy, proving that "JC's" understanding of the language and the views of god for the contexts he is writing in, not so easy, proving that JC's approach suit others ... not so easy.... unless you don't look for that and have faith in it being right in the first place.
As historical documents the bibles is useful .... perspective of God expressed ?
God that I though JC himself mentioned was not understandable by the mind of man let alone
capture-able by the languages of mankind... Logically ? No.
Hmm ... faith is a super placebo, the power of belief I think is real,
in a word faith is confidence in life for whatever you are thinking ...
which I do beleive in.
