That's one of the ways we know this isn't the 2nd Coming...At the 2nd Coming many of the evil ones will again be taken away...
rapturists claim that the “generation” of which Jesus was speaking is not the one that heard Him say these words. Jesus gave various signs to warn His followers of a tribulation about to break over them. Rapturists say that the generation Jesus refers to is the one that first sees the signs Jesus has described.
Jesus tells His disciples that it does get much worse. Up until now, the signs have been rather general and impersonal, but now the tone changes: “They will deliver you up to tribulation, and put you to death; and you will be hated by all nations for my name’s sake” (Matt. 24:9).
persecution came early, very early, in the Church’s life. The Sanhedrin persecuted Christians in Jerusalem and used the synagogues as a base for persecution elsewhere in the empire. But the persecution of sign 5 would come not only from the Jewish leaders in the synagogues. Jesus tells His followers, “You will be hated by all nations for my name’s sake.”
The ancient Roman historian Tacitus has documented Nero’s persecution. Christians became hunted creatures in the empire. Many met their death in the Coliseum in Rome as the audiences cheered and jeered. Some were strapped to stakes in Nero’s gardens and burned alive as human torches (AIR, XV, 44). St. Peter and St. Paul seem to have been martyred in Rome during this time. In Jerusalem, Bishop James, the cousin of Jesus and the author of the New Testament book that bears his name, was martyred.
