The problem is..imo...
When trying to use the Bible (and for the record I believe in God very much) as a defense and offense from others also using it to justify and support their guesses.....They have the mindset that THEY alone understand it correctly...like for example..how far would you get arguing with the author of a book concerning what exactly he was saying and which words he meant to be taken literal and which should not?
You are going to get nowhere like that.....
Trying to debate with someone using the bible..is going to be as successful..unless you can point this out to them and remind them they have no more understanding than you...they will no longer be able to successfully use their delusions of grandour to defend their positions and guesses into the unknown.
I can only wonder why this situation has been allowed to be continue unopposed for so long....It seems like such a simple problem that compounds into a bunch of confusing, hard to understand ones.
I am not into being gullible by choice.....
