God is a concept. This is not to say that God isn't real, doesn't possess genuine being, isn't sentient, etc. It's just to say that apart from what God chooses to specifically reveal to us about Godself, we are left to invest the concept of God with whatever meanings we choose. Now, I tend to believe that God revealed herself in the person of Jesus. Still, the best record we have of that event is indirect revelation. What we are left with is a Bible full of metaphorical language about God.
Like Barth, I believe the metaphors are part of revelation. I believe that they contain some "truth" about God. But metaphors are limited because our understanding is limited. The best language we have doesn't quite work. So the Bible has language like born again, father, spirit, soul, etc. Janet informed me that I needed to be born again. Gee, thanks, I think. That's helpful. Now I'll get busy getting born again. How do you do that exactly?
Like Adam, I'm growing less comfortable with God-talk. Until people grasp the idea that God is a concept, I'm not comfortable talking to them about God. They're going to think I'm a heretic. The tsunami post generated some good conversation about this. Is God good? How do we conceive good? How do we think of God? Is God all-powerful? I don't think so anymore. Does God know everything? I don't think so anymore? Is there a trinity? I think I believe in some sort of threeness grammar, but Trinity with a capital "T"? I don't know anymore. Our best attempts to understand the concept of God run into the metaphor problem. We still talk about Trinity as three persons. That language was an attempt to understand God. It's not like there are three persons named John, Joe, and Sam up there playing the role of God. So, how much can we know?
