After the two demon invasions of the 5th and 6th Trumpet Judgments, a mighty angel gives John the remaining revelations of judgment in a "little book". These are the judgments of the seven Bowl (or Vial) Judgments. But before all of this, he is given a picture of the two prophets who will have supernatural ministries during the first half of the Tribulation.
