What's pretty amazing is that someone who was a repeated, abject, and complete failure as a forecaster is still taken remotely seriously.
Yes, he can talk all he wants, but I am willing to research a particular prophetic scripture especially when I haven't read before. In this case it isn't so much Hal, but the Bible verse I found interesting. It's very clearly stated which doesn't appear to be open for much interpretation, except for when. I'm certainly not in a hurry to see it unfold, honestly. But, when it does (regardless of whose lifetime) we/they can say 'it was prophecied'.
