At one point I was thinking about the supposed "problem of the silence of God." I got on a little rant, which I never wrote up and published (maybe I should have) listing all kinds of special revelations. (I realize your main post is on general revelation.) I started with the Garden of Eden and went through Abraham, Moses and the plagues of Egypt, Sinai,...on to Jesus' miracles, the resurrection...Well, you get the drift. And then I stopped and said (to an imaginary audience): "So, tell me again about the silence of God."
