When the Rapture happens, those left here on earth will NOT accept the biblical explanation, and instead will insist it was an "alien invasion" that removed some of the people from the earth.   And those left on earth will be terrified that whatever happened to the missing people might yet happen to them!   And in the midst of this chaos the antichrist will arrive with satanic solutions to unite the world.   And hence will the 7 year Tribulation begin, and will culminate with the Second Coming of Christ, Israel's long rejected Messiah.
