@thefinn @mjdigspigs @Kalogerosstilitis2RevengeoftheJunta It's feelings-based, though it's described as piety-based. The only way to self measure piety though is to do what "feels" pious. Puritanical Protestantism was measured by outward success; if you were blessed and truly pious (and truly saved by a Calvinistic god), you would have lands and goods and so on.

That model didn't catch on with the many waves of poor immigrants over the next hundred or so years, so it became more Quaker and Methodist influenced; how close do you "feel" to God?
