SOURCE: http://www.ecclesia.org/truth/solution.htmlEven C.S. Lewis, the respected Christian apologist and author, wrote in a 1960 essay, "'Say what you like,' we shall be told, 'the apocalyptic beliefs of the first Christians have been proved to be false. It is clear from the New Testament that they all expected the Second Coming in their own lifetime. And, worse still, they had a reason, and one which you will find very embarrassing. Their Master had told them so. He shared, and indeed created, their delusion. He said in so many words, 'this generation shall not pass till all these things be done.' And He was wrong. He clearly knew no more about the end of the world than anyone else.' It is certainly the most embarrassing verse in the Bible." Essay "The World's Last Night" (1960), found in The Essential C.S. Lewis, p-385.
Do you hear what these critics and even C.S. Lewis are saying? They are saying Jesus was literally wrong when he made numerous time-restrictive predictions and statements regarding his coming, his return. This was, and still is, the crack that lets them in the door to begin their systematic criticism and dismantling of Scripture with its inevitable bankrupting of the faith.
