The premise supposes a being we can't really understand.
I think that I'm inclined to agree with Goat.
The "Flying Spaghetti Monster" is kind of an attempt at sarcastic flippancy, I guess.
But it probably does have a more serious philosophical point, as a reductio-ad-absurdem of certain kinds of justifications for belief in God.
If somebody tries to insist that faith justifies their assertions that God exists, then it's easy enough to reply that people can potentially have faith in anything, however absurd it might be. If conventional sensory evidence isn't necessary to establish God's existence, then what prevents people from announcing that any number of imperceptible things, however absurd, are silently flapping and invisibly slithering out there?
My agnosticism causes me to have quite a bit of sympathy with that line of argument.
I agree with Geoff's point here - insofar that some people cannot relate to the God of the Bible.
But many people have done so in the past and do so nowadays.
I don't think this has much to do with God as such, Biblical or otherwise, but rather with the particular moral system of the people who believe in a particular version of God.
On a few occasions, I myself was close to joining a Christian church (each time a different one). I never went through with it, though. I felt alienated from the people there. I thought this was because I didn't have the right or didn't have enough belief in God (and the church members would tell me so too). But in hindsight, I also notice that I simply didn't have much in common with those people - we had nothing to talk about, we were as if from different worlds.
For example, they saw no problem with eating meat, and belittled vegetarians. That was one big issue on which we divided. Then our views on the consumption of alcohol, coffee, cigarettes, sex, also differed radically. So did our views on art, education, politics. On communication and relationships. On philosophy.
I can imagine that someone with views like theirs would find the God of the Bible perfectly acceptable, along with the particular epistemology of what to someone else may seem faith without evidence.
Morality supersedes epistemology.
(Note, for example, the importance that Buddhists give to virtue!)
EDIT:
Note how Jehovah Himself called the Israelites "stiff-necked people" and that He Himself was apparently not all that fond of them:
Exodus 33:1-3
New International Version (NIV)
1 Then the LORD said to Moses, “Leave this place, you and the people you brought up out of Egypt, and go up to the land I promised on oath to Abraham, Isaac and Jacob, saying, ‘I will give it to your descendants.’ 2 I will send an angel before you and drive out the Canaanites, Amorites, Hittites, Perizzites, Hivites and Jebusites. 3 Go up to the land flowing with milk and honey. But I will not go with you, because you are a stiff-necked people and I might destroy you on the way.”
What we have is the Bible written from the perspective of Jews and Christians. But we don't hear much about God's perspective as such, other than indirectly from the perspective of Jews and Christians.
