Inerrantists (i.e. the kind of people who thrive on religious dogma) have built up an entire religious / epistemological system on the assumption that there is a flawless set of sacred texts from which they can derive immutable truths. It gives them an artificial sense of certainty / security, and is set up so that if that assumption gives way, their entire world view (i.e. belief system) is destroyed.
They also enjoy singing “Jesus loves me, this I know, for the bible tells me so.”
An entire life of ignorant bliss gained by such forms of “trusting and obeying” Jesus is virtually impossible to argue against, largely thanks to our dear friend “cognitive dissonance”.
