What do you mean? I do not mean to suggest that it is impossible for people to have any conception of what a God is, or that people are completely incapable of understanding him. I mean only to say that when people assume what God would say/do if they were to have a conversation with him, they do not know what he would say, so they can not assume. Also, if people believe in God, there is no way that they do not appreciate him in some way. IF they did not appreciate God, or if they did not know what it was that they were talking about, then they would have had no reason to believe in him in the first place. The simple fact that they do implies that there is something about the concept of God that they can appreciate.
