It CAN teach something actually.<quoted text>
There is a difference between knowledge, which are the ideas that derive from observing reality and which can be applied to life to effect better outcomes, and the fluff of the bible, which is sterile however deeply you examine it.
A knowledge of neuroscience, for example, is rewarded by using it to make accurate medical diagnoses. Diseases correctly identified can often be treated to some benefit - people may feel less pain or nausea, or function a little better, or live a little longer. At a minimum, a better prediction what to expect is possible.
What can bible study yield that is anything like that? Nothing at all, which is why I rejected Riverside Redneck's comparison of the benefit of studying to neuroscience to studying his bible.
I also reject his claim that any amount of studying of the bible can produce any knowledge at all, let alone a deeper understanding with more study.
It can teach us how barbaric biblical times were, that we SHOULDN'T just kill everything we disagree with.
It teaches all that is immoral, for many rules in the bible are immoral.
