One problem is that the Bible sez he's wrong!
"No one knows about that day or hour, not even the angels in heaven, nor the Son, but only the Father." Matt. 24:36.
Sooo. This 89 year old prophet of doom knows better than God? Nice one, Harold! And fancy doing this when - without being hurtful, I hope - at your age you are so close to meeting Him!(Do look up scriptural references to false prophets, won't you?)
