The second, third and fourth trumpets speak the same voice, "a third part of," what the context speaks of. These were to be the conditions of the earth and its environment as the trumpet soundings progressed, where these signs would be seen globally on the earth.
1st trumpet, "And the third part of trees was burnt*(past tense) up, and all green grass was burnt* up." 2nd trumpet, "And the third part of the sea (sea of peoples) became* blood. And the third part of the creatures* (animal or human) which were in the sea, and had life* died, and the third part of the ships were destroyed." 3rd trumpet, "And the third part of the waters became* wormwood; and many men died of the waters, because they were made bitter." 4th trumpet, "The third part of the sun was smitten* (was effected), and a third part part of the moon, and a third part of the stars; so as the third part of them was darkened, and the day shone not for a third part of it, and the night likewise." The language given here are figures of speech to have a deeper and spiritual meaning, but when taken in a general literal sense, these are the conditions to be seen on earth at that time. These verses tell us that these will be the general conditions of the earth and its environment at that time of what the context discloses. And these are the signs that would be present when these four trumpets will have been sounded. And who can deny that they all have arrived and have become fact for at least a decade now?
The beginning fulfillment of the prophecy can be seen after the 4th trumpet is sounded, for there we have a warning given us, after these events would have occurred. "And I beheld, and heard an angel flying through the midst of heaven, saying with a loud voice, Woe, woe, woe, to the inhabiters of the earth by reason of the other voices of the trumpets of the three angels, which are yet to sound!" (Rev. 8-13). Before continuing, what must be understood here is that much of the book of Revelation was given in a symbolic, parabolic and figurative language. Given us in this way, to make us aware of the spiritual meanings behind it, for that is the main message intended of what to look to concerning its literal fulfillment. The key to understanding this is that it is God's judgment on the church as well as on the world. That which scripture calls "the falling away" that would occur "before" the tribulation would begin.
The phrase "the third part of men" is a symbolic phrase that points to those in the body of Christ, the church. This can be seen in Zech. 13-8-9, where God speaks of the world and symbolically divides two groups of people. The unsaved are seen in the number two thirds, and the saved by the number one third. "And it shall come to pass, that in all the land (the world here) saith the Lord, two parts therein shall be cut off and die; but the third shall be left therein. And I will bring the third part through the fire (judgment), and will refine them as silver is refined, and will try them as gold is tried; they shall call on my name, and I will hear them; I will say, it is my people; and they shall say, the Lord is my God" (see also Dan. 11-35,12-10 and Mal. 3-2-3). The one third are God's people. In Revelation 8-9, the one third are pictured as being dead or killed. This is seen in Rev. 11-7,13-7 and 13-15. They have been killed spiritually, for the church which they belonged is no longer the fountain of life. Much of the body of Christ has been overrun with false gospels and false prophets, and no longer bring rivers and fountains of the living waters of life; they have become Wormwood. The figures of speech, trees, sea, creatures, rivers, and etc. can be seen in their context to represent the church. The death of the "third part of man" must be understood in that respect and in the same way as the death of the two witnesses in Rev. 11-7; they, and others, die spiritually.
A list of the figures of speech used in the 4 trumpet verses that represent the church will be given here, with the Bible being the interpreter. 1. Creature(s)--Ezek. 1-5, Mark 16-15, 2 Cor. 5-17, Col. 1-15, Rev. 4-6. 2. Trees--Proverbs 15-4, Psalms 1-3, Ezek. 31-8-9, Mark 8-24, Jude 12. 3. Grass--Matt. 13-26, Mark 4-28, 1 Peter 1-24, James 1-10-11. 4. Waters--Gen. 49-4, Psalms 22-14, 2 Peter 2-17, Jude 12, Rev. 17-15. 5. Rivers--Isa. 32-2, John 7-38, Rev. 17-15. 6. Sea--James 1-6, Jude 13, Rev. 17-15. 7. Moon-Sun--Judges 5-31, Jer. 15-9, Mal. 4-2, Matt. 13-43, Rev. 12-1,21-23,22-16. 8. Stars--Dan. 8-10, Jude 13, Rev. 8-12,12-4,22-16. 9. Light(s)--2 Phil. 2-15, 1 Thess. 5-5, and etc. 10. Ships (vessels) congregation (s), sanctuary, temple, individual, in the sea and in the church of the world.
In the first trumpet, the trees represent the congregations of the body of Christ, where it is said that a third part of these have been "burnt up" at the time of this sounding. The green grass here represents the individual, and all are seen as being "burnt up." This means Satan using the beast and false prophet "shall wear out the saints," and for others the loss of morals and morality. These have withered away and become "burnt up." (Psalms 1-3). At the second angel's sounding, "as it were," to mean figuratively speaking, "a great mountain burning with fire was cast into the sea;---." The word "mountain" here is symbolic to mean a "kingdom" with a king. This is seen in Rev. 17-9-10, in Daniel and elsewhere in scripture. This mountain kingdom burning with fire represents God's judgments on her because of her actions. This kingdom was cast into the sea, a figure of speech of her coming downfall seen in chapters 17 and 18. The creatures in "this sea" are men (peoples) that had life, "died". They died spiritually as well as physically. The third part of the ships, "vessels" destroyed represent man as an individual as well as collectively, to mean a congregation and congregations. A third of these congregations would be destroyed.
At the third angel's sounding it is said there fell a great star from heaven, burning "as it were," to mean figuratively speaking, like "a torch, a lamp or light, and it fell upon the third part of the rivers and fountains of waters." This great star that fell from heaven seen as falling upon these waters at this 3rd sounding, is what Rev. 9-1 speaks of there; "the star that "had fallen from heaven" when John seen it, there seen as being on the earth. Scripture tells us that Satan and his followers come as angels of light. This great star seen in the 3rd angel's sounding is this "torch or light" beginning to effect the "waters" of the earth. These congregations of rivers and fountains of waters that help bring forth life, through the grace of God, Christ and the Holy Spirit are at that time becoming polluted. (see John 7-38). The name of the star is called Wormwood, to mean bitter, polluted, and not fit to intake, to digest. These waters made bitter represent people and congregations, that now hold false doctrines, false prophets and fallen believers, causing many to spiritually die because of these "bitter waters" they were made to drink.
This 4th angel's sounding is now to include Israel as well as the church when it would be sounded. This refers us to Rev. 12-14, where the woman, Israel, is seen clothed with the sun. Here the sun represents Christ, who is called the "Sun of Righteousness" in Mal. 4-2, Luke 1-78 and Rev. 22-16. The moon also represents Christ, "the moon under her feet" as being their light, as well as the light of the church, and holds dominion over all. The reverence to the sun and moon is seen in Rev. 21-23, "For the Lamb (God) is the light thereof." That which caused the third part of the day and night not to shine are Satan's followers. This is seen in Jude 13, "Wandering stars to whom is reserved the blackness of darkness forever." These are they that caused a third part of the body of Christ to be darkened by this 4th trumpet's sounding. We read in 2 Phil. 2-15 what we represent. "---Among whom ye shine as lights in the world." This is also seen in Matt. 5-14-16 and 1 Thess. 5-5-7, where we read; "Ye are all the sons of light,--the sons of the day, we are not of the night, nor of darkness." This means our light should shine even during the night. "Therefore, let us not sleep, as others; let us watch and be sober. For they that sleep (stop shining), sleep in the night;--." They have no light and are now in darkness.
As was noted, when the conditions of the first 4 trumpet soundings will have sounded, the 5th angel would then soon begin to sound his trumpet as John recorded. "---An angel flying in the midst of heaven, saying with a loud voice, Woe, woe, woe, to the inhabiters of the earth by reason of the other voices of the trumpet of the three angels, which are yet to sound!"
