The assumption the other person doesn't know.

[Darkstar]

I know many Muslims, they always assume, non-Muslims when it comes to moral issues opposing Islam (or a version of Islam), don't know. For example, they don't know for sure it's wrong to kill apostates for apostasy.

But once you step into that knowledge yourself, you feel like, wait a minute, didn't I sort of hear that call towards it being wrong, but didn't listen to it deep within for various factors?

The question is, are you guys willing to say it's possible, the same is the case of knowing God via not knowing him.

That people assume the other people don't know, just like many Muslims assume people don't know killing apostates for apostasy is wrong but that once you step into that knowledge, it becomes clear?

I'm not arguing what is the case, just whether it's logically possible.

But that is an apparent truth, clearly the existence of god isn't, otherwise there wouldn't be atheists. If I have a deck of cards and declare that the top card is the king of clubs, and it turns out to be so am I psychic or just lucky? Did I 'know' it was, or was it just by chance? In your example, people knew precisely because religion is unnecessary for a solid moral foundation. The existence of god isn't really the same. In short, yes:it's possible to know something without being explicitly told it, but, I don't think that applies to god.
