God lives within us faith.

[Tonus]

I think if God would write words in the sky saying he exists, it would make faith dry and too easy and dull.

I think faith in the unseen and the unseen journey is a more enriching experience.

That seems more like a question of human psychology. We are driven to justify our actions and beliefs to the degree that we may even conform to something that we invented specifically to explain an action or attitude we didn't really mean to take. It is like the scenes in those Pink Panther movies, where the bumbling Inspector Clouseau, having taken a nasty pratfall, insists that he had intended to do so the whole time.

You cannot find god, but you want to believe that he exists and that he cares for you. So you determine that hiding from you is really the best possible approach that he could take-- that revealing himself would be far more of a negative than a positive action, regardless of how bizarre that seems. "God" is indeed within all of us, if we define "god" as that internal drive that makes us whoever we are. But that's it, really. And "god" works to our detriment more likely than not if we let him run the show.
