For thousands of years, prophets have predicted the end of the world. Today, various religious groups, using the latest technology, are trying to hasten it. Their endgame is to speed the promised arrival of a messiah. For some Christians this means laying the groundwork for Armageddon. With that goal in mind, mega-church pastors recently met in Inglewood to polish strategies for using global communications and aircraft to transport missionaries to fulfill the Great Commission: to make every person on Earth aware of Jesus' message. Doing so, they believe, will bring about the end, perhaps within two decades. In Iran, President Mahmoud Ahmadinejad has a far different vision. As mayor of Tehran in 2004, he spent millions on improvements to make the city more welcoming for the return of a Muslim messiah known as the Mahdi, according to a recent report by the American Foreign Policy Center, a nonpartisan think tank. To the majority of Shiites, the Mahdi was the last of the prophet Muhammad's true heirs, his 12 righteous descendants chosen by God to lead the faithful. Ahmadinejad hopes to welcome the Mahdi to Tehran within two years. Conversely, some Jewish groups in Jerusalem hope to clear the path for their own messiah by rebuilding a temple on a site now occupied by one of Islam's holiest shrines. Artisans have re-created priestly robes of white linen, gem-studded breastplates, silver trumpets and solid-gold menorahs to be used in the Holy Temple - along with two 6½-ton marble cornerstones for the building's foundation. Then there is Clyde Lott, a Mississippi revivalist preacher and cattle rancher. He is trying to raise a unique herd of red heifers to satisfy an obscure injunction in the Book of Numbers: the sacrifice of a blemish-free red heifer for purification rituals needed to pave the way for the messiah. So far, only one of his cows has been verified by rabbis as worthy, meaning they failed to turn up even three white or black hairs on the animal's body. Linking these efforts is a belief that modern technologies and global communications have made it possible to induce completion of God's plan within this generation... According to various polls, an estimated 40% of Americans believe that a sequence of events presaging the end times is already underway. Among the believers are pastors of some of the largest evangelical churches in America, who converged at Faith Central Bible Church in Inglewood in February to finalize plans to start 5 million new churches worldwide in 10 years... "As we advance around the world," Davis said, "we'll be shortening the time needed to fulfill that Great Commission. Then, the Bible says, the end will come."... A growing number of fundamentalist Christians in mostly Southern states are adopting Jewish religious practices to align themselves with prophecies saying that Gentiles will stand as one with Jews when the end is near. Evangelist John C. Hagee of the 19,000-member Cornerstone Church in San Antonio has helped 12,000 Russian Jews move to Israel, and donated several million dollars to Israeli hospitals and orphanages. ...Bill McCartney, a former University of Colorado football coach and co-founder of the evangelical Promise Keepers movement for men, which became huge in the 1990s, has had a devil of a time getting his own apocalyptic campaign off the ground. It's called The Road to Jerusalem, and its mission is to convert Jews to Christianity - while there is still time. "Our whole purpose is to hasten the end times," he said. "The Bible says Jews will be brought to jealousy when they see Christians and Jewish believers together as one - they'll want to be a part of that. That's going to signal Jesus' return." Jews and others who don't accept Jesus, he added matter-of-factly, "are toast."... Some Christians, such as Roman Catholics and some Protestant denominations, believe in the Second Coming but don't try to advance it. It's important to be ready for the Second Coming, they say, though its timetable cannot be manipulated.
