just because it doesn't align with what you've observed doesn't mean it's "mental". that's rude. please be constructive.
No judgement in if you do that, good for you. However the point is not that it's too much reading or w/e, but rather that it's far more than the typical christian cares to do. To assume christians actually do that is the mental part, but you choosing to do; if that makes sense.
edit: To the downvote, do you honestly think the majority of christians in America, some self proclaimed 70% of Americans iirc, read several passages a day? Really?
It turns out about 27% of Americans[0] read their Bible several times per week, with more than half of those reading it daily.
