Well, we certainly can tell who has inspiration and zeal for learning all they possibly might find out about God, God's people, God's next move(s), etc.

Fortunately the indicators are just as evident related to those who already know God - the TRUE God that is. The weight born by these unfortunates as they wander through life (this & next) must be horrendous! After all, how would a mere mortal know all about God, all about God's future, details of God's past, and or course, of God's master plan for their life... unless, of course, he be the One, True, God. (or she.)
