There are a total of twenty-one special judgments that fall upon earth during the Tribulation period. They are in three series of sevens described as seals, trumpets, and vials (or bowls):
This is the beginning of the program of God to pour out judgments upon the earth. I encourage you to open your Bible and read each judgment carefully to understand the finality of God's pronouncements. These include:
The trumpets of heaven sound an alarm throughout the world announcing the public judgments of God. Each blast ushers in an added judgment.
These twenty-one judgments unleash unbelievable war, ecological disasters, and atomic catastrophe on our earth. Note this judgment in particular; Revelation 14:20 reads, "And the winepress was trodden without the city, and blood came out of the winepress, even unto the horse bridles, by the space of a thousand and six hundred furlongs." According to today's calculations, that is a river of blood two hundred miles long-the exact length of the nation of Israel. Think of it! An entire nation saturated and soaked with blood. As believers, you and I can be grateful that the Rapture is coming, because it means we-the Church of Jesus Christ-will not be present to endure this terrible suffering. The Bride will be at home, at the marriage ceremony, and afterward return for the supper (Revelation 19:7-16).
