"In the 1980s one Bible teacher thought that he had proof that Christ would return on a certain day in September 1988. He sold two million copies of his book, listing eighty-eight reasons for his beliefs. Many Bible students felt he had convincing arguments in support of his prediction. Some people sold their houses and gave away their money. Some terminated their employment in order to spend all their time getting ready. Some of his followers even had their pets put to death because they did not want to leave them behind when the Lord came. However, the day came and went and nothing occurred."
John Walvoord on Edgar Whisenant's book. (Walvoord, p. 1257, in Understanding Christian Theology)
