I think a lot of "theists" might be nominal, might be sort of just lying, pretending, and are mainly atheists inside and don't really believe, and can't really believe, because their idea or ideas about God just don't make sense to them and seem too unrealistic, and so they may say over and over again they believe but haven't experienced anything which really makes them truly believe so that its all talk. They too would be expected to be living an empty shell of a life.
