The only problem with your approach is that God cant be agreed upon as to character. All we have is a bunch of human(and in my opinion flawed) ideas as to who or what God is.
I agree, to an extent of course. Again, if we're simply saying "the creator of everything" then I think we can all agree. Unless someone has some radically different image of God that I've never heard of. So while specifics may never be agreed upon one certainty is true: we are speaking about the creator of everything.
My point was, according to ICANT many don't read the
Bible and thus deny God's existence. But if we, as you say, have only ideas as to who or what God is, then the Bible is only 1 of thousands of ways to "know" God or believe in his/her existence.
But here again I'm off topic so, feel free to ignore this message.
