That's easy. They bore the crap out of you with endless unrelated scriptures until you just "check out", nodd your head and just get past it all.
It's kinda like when the used car salesman has you in his office signing hours worth of paperwork. At first you read it all. Then after a while you just sign away your firstborn child just to get the hell outta there.
Isn't it embarrassing how we bought in to this crap at one time?
