When the fourth angel sounded his trumpet a third of the sun and the moon and the stars were struck so that a third of their brightness and heat would be reduced.
Again, we don’t know exactly what the cause of this phenomenon is. John MacArthur suggests that it is a supernatural act of God, that He “will supernaturally reduce the intensity of the celestial bodies by one-third.”4 Hal Lindsey believes that the “light reduction will result from the tremendous pollution in the air left from nuclear explosions.”5
In either case, the result will be a radical drop in temperature, producing great changes in weather cycles as well as botanical and biological cycles. More importantly, these changes will make it much harder for all humans to live on planet earth.
But there is a second part to this trumpet judgment. As the earth is still suffering from a great loss of heat, John looked and saw and heard an eagle flying across the sky saying (the eagle will be speaking!) with a loud voice, “Woe, woe, woe to those who dwell on the earth, because of the remaining blasts of the trumpets from the angels…!”
So, it seems that God is warning all those who are still living, that the remaining three trumpet judgments are soon to come, and that they will be worse than the first four. I can’t imagine what people will think or do. How will they prepare? We can only hope, but we can also pray, even now in advance, that they will turn to God and seek His salvation.
