Well, if that is the case, we must assume that God also isn't interested in whether people believe in him or not. If he's not interested, why are you?
In which case, what is it you think should persuade those left "wondering" to believe? If God isn't interested in them, why should they be interested in God?
This denies your point 2, because it seems to apply to all. But in that case, since God is waiting in utter silence, how comes it that there's such a big noise about him, all based on what he's supposed to have inspired in various scriptures?
I presume you mean something has blinded the awareness of SOME humans. But isn't it just as possible, or perhaps even more possible, that something is causing SOME humans to imagine what isn't there? And given the fact delusional thinking is rife within our species, I lean to the "very likely" rather than even more possible side.
Well, at least this has the benefit of fitting well within Occam's Razor. It's the simplest answer to the obvious question, so might well be the best answer, too.
