What about the gullible, the desperate and easily convinced versus the empirical and skeptical? The former have such an easier time relying on faith while the latter are basically setup to fail and be condemned.
In that same vein the people of the last 1700-1900 years undoubtedly found it easier to believe and hold onto faith. Having lived through the information age where things like magic and most would-be, miraculous phenomena are now readily explainable, faith has to be exponentially more difficult to come by for us. Humans are more set up now for damnation than at any other point in history AD. Can't listen to a thunderstorm roll by or see a rainbow after and think as easily "God created that."
