I remarked on this phenomenon in connection with preaching on Isaiah 7:10-14, this "I have serious, profound questions that I really don't want answered" phenomenon.
But asking isn't always a Golden Key. Try talking with a Roman Catholic about what the Bible says about... well, about anything. I was going to say "about Mary." They'll cut and paste from their stock web sites (sound familiar, in the crevo connection?) until Jesus comes back. Anything except candidly admit, "Yeah, well, the Bible does say / the evidence does show ______ — but I have a prior philosophical commitment to which I have greater allegiance."
Dan
And its opposite, "I ask questions they won't answer" phenomenon.
