Parking the prophet and taking the Bible as final and one and only
The catastrophic events that are signs of the end of the age are so unique that no mistake is possible. The shaking up of human openness to Scripture by people who have new and essential information is an added catastrophe. One cannot mistake the sun for the moon. The sea will not pass as the land, and when the angelic hosts get active no one should be mistaking their moves for God’s. The trumpet warnings and bowl plagues are designed to call attention to God’s fingerprint.
Trumpets and vials
The certainty of last day events comes from three evangelists reporting Yeshua’s message (Matthew 24, Mark 13, and Luke 21). We see the further enhancement of the certainty of last day events in the three series of seven announcements. These appear in the seven seals, seven trumpets and seven bowls (vials) of the Book of Revelation. An example of a distinct must happen is the 6th trumpet. When it sounds a third of humanity dies! The decrees of the trumpet series are interventions that seem to serve as the plagues on Egypt. The trumpets are woes; rock-your-world happenings. These next verses set up trumpets 5, 6, and 7 as woes.
Then I looked, and I heard an eagle crying with a loud voice as it flew directly overhead, “Woe, woe, woe to those who dwell on the earth, at the blasts of the other trumpets that the three angels are about to blow!”
Rev. 8:13
The fifth trumpet = first of the three remaining woes.
The first woe has passed; behold, two woes are still to come.
Rev. 9:12
The scope is devastating
When all green grass disappears we will know.
- A hail, fire, and blood mix, thrown on the earth: and the third part of trees was burnt up, and all green grass was burnt up. (8:7)
- A third of the sea was turned to blood (8:8)
- A third part of the creatures which were in the sea, and had life, died; and the third part of the ships were destroyed. (8:9)

Those plagues of Revelation 9 cannot hide and hardly need anyone to announce them.
