This goes both ways. A person can evaluate any belief structure he buys into by a few well chosen questions and his responses to them. Try the following.
There is no God this is a fact. true, somewhat true, maybe true, false.
Did you pause to think about this? did you consider the alternatives? Would you ask people to accept this statement as a fact and not analyse the alternatives for themselves?
Complete sexual freedom is beneficial for society. true, somewhat true, maybe true, false.
Did you pause to think about this? Do you think the question encompasses a lot more issues than one simple statement can express? Do cultural demands drive our viewpoints?
Disbanding all religions will end war. true, somewhat true, maybe true, false.
Enough people blame religion for wars totally as a cultural norm and promote this viewpoint. If you believe this did you think this statement completely correct without a pause? If you think war is more complex than this did you think this statement a false one straight away?
A person can look at road rules and see the benefit to them by personal analyse. But this equally applies to the bible and what it teaches. It can also be measured and evaluated.
If I look at a road sign saying "children crossing" indicating I slow down. I immediately see the benefit of it for both myself and the children. In future I program myself to obey this sign and no longer think about it since it has already been processed.
We can do the same with bible teachings seeing the benefit of teachings on morality etc obviously evaluating them initially to see whether we accept them. Do we then keep evaluating our original decisions so as to reasure ourselves?
Are you saying we cannot have confidence in a biblical setting without it being a cult mindset?
