In 1987, a man published a booklet that presented 88 reasons why Christ would return in 1988. Though many thousands were sold, the book was doomed to be wrong. Christ himself said that no one knows when he will return. In Christian theology, what we can know is revealed in the Bible. When Christ will return cannot be known. When it comes to what cannot be known, multiple reasons, evidence or collaborating authorities are worthless. What by nature cannot be known remains unknown no matter what.
