Even with all of “Man’s” meddling with the written form of the bible over the ages (and especially the last 2K years), it seems fairly certain that GOD has allowed to survive (that process) what is needed, if not an absolutely perfect reflection of HIS WORD.
I think that the most important notion is one that inductive reasoning, when it comes to discerning GOD’s WILL, only increases the odds of moving away from it. .
