On Friday, a teacher told his class that he was going to give a surprise quiz the following week. One clever student—we'll call him Jamie—went home and thought about this pop quiz. He didn't know the subject very well, and was upset that he was going to miss his whole weekend to study. Jamie tried to figure out what day the quiz might be. First, he noticed that it couldn't be Friday, because if they got to Thursday and hadn't had the quiz yet, then everyone would know it was on Friday, and the teacher had said it would be a surprise. Friday is out. Well, now the text couldn't be on Thursday, because if they got to Wednesday with no quiz then everyone would know the quiz was on Thursday, because Friday was already ruled out. Thursday is out too. By the same logic, the test couldn't be on Wednesday or Tuesday. That left Monday as the only possible day, so a test given that day wouldn't be a surprise. Jamie figured out there was no way for the teacher to give a surprise pop quiz, so he spent his weekend playing with his friends, going to church and youth, and watching Monty Python movies. Anyone want to guess what happened? The teacher gave the quiz on Wednesday morning, Jamie was surprised, and he failed.

Did I tell this story just to embarrass Jamie? Certainly not. We read Jesus' prophecy about his second coming, especially the part about the present generation not passing away before all these things come to be, and we reason that since, as far as we understand, part of the prophecy was not true, we should just read this all as a nice set of symbols. That part about expecting the master to come home and keeping awake—we don't really need to do that, because he hasn't come back in the past two thousand years. The odds are pretty good he won't come back this year either. Well, the odds were pretty good Jamie wouldn't fail the pop quiz.
