Many things still need to happen before the Rapture, Elijah has to come and have a ministry before the Tribulation and he may be one of the Two Witnesses when the Trib starts. A middle east war must happen and must end then Israel burn those weapon of that war for 7 years before the Trib. Antichrist must sign a 7-year peace treaty covenant then the Two Witnesses must bring plagues on the Church and on Antichrist before the Rapture.
