The document discusses the tribulation period that is prophesied in the Bible to occur after the rapture of the church but before the second coming of Jesus Christ. It provides definitions of the tribulation, explains that it is a time determined for Israel according to prophecies in Daniel, and will last for 7 years based on calculations from Daniel's 70 weeks prophecy. Events described taking place during the tribulation include the ministry of two witnesses, Satan being cast to earth, and the beast being given power for 42 months. Arguments for why the church will be raptured before the tribulation include that the church is not appointed to wrath and is the bride of Christ.
