I agree. Robert's mind is quite closed and nothing short of a crowbar will open it. He just redoubles his efforts and moves onward, ignoring any and all reasoned discussion. Such is fanaticism.
I read his "Prophecy and the Church" (or at least the first part of it) years ago and was quite impressed by his thoroughness. If you look online under Allis on Dispensationalism (or something like that) I think what you find is part of that book (but I need to double check my copy).
I suggested a book by Lindsay - actually not an exhaustive one, just in paperback.
I am busy too. I think retirement is a practical joke invented by someone in the marketing dept. :D
