As Phizzy points out Bible "literalism" as practised by JW org, is a relatively modern interpretation by those who were appalled by the presumptions of critics who would dare question the Bible's truthfulness. At that time to discredit the Bible was the equivalent to re-introducing savagery to polite society.
At the bottom of nearly all the religious discussion on this site is the conflict believers have with wanting to do the right thing but are confronted with a set of 'holy scripture' revealed to be at odds with scientific analysis.
Believers feel they have a choice of beliefs and that on balance belief in God is the best choice, it happens to be unsupported by facts but has the advantage of 'spiritual'rewards. On the other hand there are those who can put emotion aside and and are prepared to look at evidence for what the Bible says, how it was compiled and most importantly why is was enforced for so long.
So we are left with two alternatives: faith in the supernatural, usually bouyed up by like minded believers, or the mature option and humility to recognise the superiority of understanding life as measured and demonstrated by rigourous scientific methods, not the least of which is scepticism.
Belief in God carries no sceptical element!
How can anything be determined without thrashing out all of the facts, evidences and opposing arguments?
Belief is arbitrary and one sided, knowlege only comes from understanding the evidence. The Bible is evidence of the brutal human values once held 2700 to 1600 years ago -- get up to date and enjoy learning to be sceptical of all information.
