The Fourth Trumpet

The FOURTH ANGEL sounded, and the third part of the sun was smitten, and the third part of the moon, and the 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 (Rev. 8:12).
Thus we see the soundings of the first four angels connected with signs and changes in almost every department of the universe. There are not only
signs in the earth beneath,
but also
wonders in heaven above {Acts 2:19}:
The earth, trees, grass, sea, fish, rivers, fountains, men, sun, moon, stars, day and night, each in turn exhibit marks of God’s interference. All these judgments have doubtless symbolic signification. Under the action of the fourth trumpet, the highest authorities are smitten — sun, moon, and stars. But all these things, together with the casting of hail and fire on the earth mingled with blood, are far less severe than the judgments that follow the sounding of the other three angels. These are specially marked by being prefaced with an announcement of an angel, saying,
WOE, WOE, WOE to the inhabiters of the earth.
And I beheld, and heard (not an angel but) an eagle 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 trumpet of the three angels, which are yet to sound! (Rev. 8:13).
This distinctly marks the last three trumpets as directly upon the inhabiters of the earth. God now deals directly with men, and that at first by the power of Satan, and then by the personal coming of Christ Himself.
