The point of such a grabbag of claims that appeal to vague sentiments of 'a good Christian life' may exactly be that it is incoherent and contradictory. Thinkers like yourself see these blatant inconsistencies and vacuous claims for what they are. A good 40% (my guess), has no driver to analyze what the author actually says. They are content with the feeling they get out of it, without realizing that they are projecting their feeling onto vague and contradictory statements.

Even when they don't realise it, they will believe contradictory statements concurrently: Cognitive dissonance. And this just so happens to be the basis in a narcissistic relationship on a personal relationship level, cult/religious level and on a political level.

The vagueness and inconsistencies allow them to fill-in the blanks for themselves, cherry-pick and feel that their own feelings are exactly what the author meant.

Confirmation-bias requires no effort, it confirms that you are right and it makes you feel good. Vagueries and inconsistencies provide all that. Why would they try to analyze the facts and the logic? The've got no incentive. Inconsistencies, falsehoods, vagueries and newspeak are no longer a bug. In order to keep their base, conservatives have made it into a feature.

Fortunately for them, their constituency, is the one that is most influenced by feelings and not by knowledge, science, facts and critical thinking. Evangelicals, conspiracy believers, proud boys, the super-rich, anarchists, trickle-down economy believers, the super-rich, the super-powerful, the Elite, the anti- elite, ... all of them are catered for by the party that calls itself the Grand Old Party (and claim that self aggrandizing is a sin).

The author of this cretinous credo may have done so on purpose to gain more sway over her flock, or is herself an impaired thinker who spouts her beliefs and is somehow allowed to publicize it (a 12 year old would have received an F for handing in such schoolwork).
