I appreciate your honesty here.
It reminds me of the situation we have in real life experiences.
The parents tell the child,
"Eat your vegetables. They are good for you. The give you vitamins that's good for a healthy body... etc."
The child makes a face.
"Ugh! They are yucky. I hate 'em. I don't want 'em. You eat 'em."
The vegetables are good. Tried and proven.
The child just has not come to appreciate that fact.
I found out why, actually. Vegetables don't trigger the brain to process dopamine for us. So the reward system in our brain doesn't click (as it does sugar) that "this is good." That's why children and some adults don't find veggies delicious (without the butter, salt, next to a fine dish) because it doesn't hit the spot.
Relate that to the bible. Say the bible (in your example) are the veggies. Some people like veggies and some don't....but the dopamine doesn't come into affect for some non-christians because they don't have experiences (salt, butter, etc) and interconnection with those experiences to make
the bible worth while. Maybe the veggies they care for is the Quran or maybe they rather practice experiencing god by Hindu tradition than reading about it. Some like corn. Some like broccoli.
So, it's not that children won't eat their veggies. Parents can present veggies with other food that makes the sacrifice worth taking. It's the default brain position. So, if one is an atheist (which is the default), they wouldn't be interested believing any god-scripture because to them there is no dopamine spike since god doesn't exist. If they're not indoctrinated, they would no nothing about god. They can either eat corn instead of green beans or find another nutrient that does just as much.
My question is why do many christians don't see alternatives of getting the same nutrition somewhere else? We can't blame the brain from doing its job and children for not liking corn... it really depends on the parents and what the brain is attracted to salt or no salt at all.
(That was a fun write)
