How bad will the last half of the Tribulation be?
The last half of the Tribulation will be beyond human description, referred to as the wrath and vexation of God. At the midpoint the Antichrist defiles the Temple and turns on the Jews, triggering that final three and a half years after the first half's semblance of religious freedom.
Les explains that the midpoint of the Tribulation begins when the Antichrist comes in and defiles the Temple, turning on the Jews. He notes that although the first three and a half years are not a Sunday school picnic for the world—with war, famine, pestilence, and turmoil—the last half is triggered at the midpoint and is beyond human description. He identifies it as the wrath and vexation of God, as referred to in Psalms 2.
