Please be sure to see the extended teaching that I gave on "What is the Tribulation" before watching this video. https://www.youtube.com/watch?v=oafM32dB3n0. It will help to explain the events that will be taking place from Revelation 6-19. So, to recap, the Tribulation is the 7 year period of God's dealing with the Jewish people while at the same time bringing judgment to the Gentile world. In Revelation 6 the judgments begin as we enter the first half of the Tribulation with the rise of the Anti-Christ.
