To bring this to a close, this writer believes most of Matt. 24 is about Israel and the Tribulation period not the Rapture, or the Church or the Church Age. Jesus answered the three questions that He was asked including the one about the end of the world (or age).
This article is about the Second Coming not the Rapture. There are no signs of the Rapture. It can happen at any time and without notice. But there are signs of the Second Coming and the church is told to watch for those signs.
This generation is full of scoffers, mocking the prophesied return of Jesus Christ to Planet Earth.
