4th Trumpet, judgement upon the skies.
Revelation 8:12 Then the fourth angel sounded: And a third of the sun was struck, a third of the moon, and a third of the stars, so that a third of them were darkened. A third of the day did not shine, and likewise the night.
13 And I looked, and I heard an angel flying through the midst of heaven, saying with a loud voice, “Woe, woe, woe to the inhabitants of the earth, because of the remaining blasts of the trumpet of the three angels who are about to sound!”
Now, to those upon the earth at this time, how scary this would be. For us, we see what great power the LORD has to cause the heavens to be altered this way. The world is consumed with these ideas of catastrophic natural disasters but without Gods approval, not global warming, they will not accure, I believe.
