All children are individuals who exhibit good and bad behavior, regardless of what their parents do for a living. Except these kids. If you're a preacher's kid in fiction, you're either a perfect little angel or--more commonly--a beastly little devil more devoted to mischief and/or promiscuity than any kind of religious study. Bonus points for being the latter while people think you're the former, an ability no doubt gained from your years of living under a household where learning to hide your extracurricular activities proves to be a tad bit more important than mathematics.
