Once again I find myself seemingly alone in disagreement with everyone, which is cool: I'm used to that, but it makes the logistics difficult. I'm going to pick slic's post to respond to because I like his references to comic books and tablecloths. I own neither of these items, so they strike me as slightly exotic

Things which are real are always just a little beyond our grasp...
I'm not sure what you mean by this, but on it's face this is ridiculous. What do you mean by real, what level of understanding are you meaning? What do I have to know about my tablecloth to understand it?
I simply mean that we can't know everything. I think it's what Carl Sagan means when he talks about the "wonder" of the universe. There is always more to find out, and that's a big part of what makes the universe so cool. We are blessed with infinite potential for growth and discovery: You can keep learning, every day, for the entire 80+ years of your life and never run out of material.
Take your tablecloth for exmample. You can take it as merely functional, and that's fine, but you if take the innitiative to really study your tablecloth, myriad paths of learning unfold. You can go from there out into ecconomics and trade: How did my tablecloth get here? History: Who first used these? How have they evolved over the centuries? Textiles: What is this made of and how? Physics: Why does this weave hold together? Etc. Every topic, even one so mundane as a tablecloth, offers great depth, if one exerts themselves to learn about it.
God is like this also: I never expect to know
everything about God, and I think anyone who claims to know
everything about God is fooling themselves quite baddly. But that isn't the same as saying that I know
nothing about God. I do know
something, and I expect to continue learning more, forever.
Sure, but what about me believing that Josh Hugo is a white guy who likes comic books and goes to church every Sunday? Probably not 100% true, but close enough that it would be very hard to convince me otherwise.
How can I tell the difference btwn what I "Know" to be true, and what I have learned incorrectly. This is exactly why I will never follow an organized religion - too many people are sure they Know God - and turn out to be hypocritical lying jerks (just check the news). Why spend time "trying to get to know Him"? Just live your life, follow the rules as best you can and let others do the same.
You can assume that I'm a white church-goer who likes comic books. That's fine, as long as you keep in mind that your assumptions are just that. Keep a distinction in mind between what you
know about me (which is simply that I have published certain statements on the web) and what you speculate. If you really want to know me better, you can take steps to do so, or you can decline to take those steps and not know. But you can't just make up stuff about me and pretend like it's true. That, I think, is the fault many of your see in "organized religion": You're expeceted to swallow a bunch of made-up stuff and not question it.
Pardon if this seems flippant, but I mean it sincerely: I don't see much difference between unquestioningly swallowing something someone else made up and swallowing something you yourself made up. Where is the logic of opting out of a religious system because it is baseless only to fabricate your own equally baseless system? Whether a dead guy made it up 2000 years ago or you made it up last week, it's still made up, so what's the difference? (Not that I think my religion is made up: I believe it's really true.)
If God actually exists–if God is real–then there are facts about Him just like there are facts about the universe, and we are not free to just make up our own ideas
If one grants this, then one would expect there to be concrete evidentiary methods for gathering information about God, in the same way that one uses concrete evidentiary methods for gathering information about nature.
Which is to say: if God existed, and existed in the same way as physical law, then he would be researchable.
There is no evidence that such a god or gods exist; there is no evidence that any god or gods exerts influence on the universe in the ways claimed by religion. (Frex: prayer does not work more than placebo.)
So, if you're going to say that God can be known in teh same ways as scientific knowing, then you end up binding God within that paradigm of knowledge. Within that paradigm of knowledge, your position as a theist is extremely tenuous, unless you worship the non-interventionist watchmaker version of god.
You're better off arguing from faith sans scientific metaphors.
And as to that, I'll simply have have to say I disagree. I see ample evidence of God, in all spheres of my experience, and I think He has provided us with the means to do a little research, should we be so inclined. You deny my evidence and my sources of information, and so we are are at a simple impasse.
