Rev. 16:8 –The fourth [angel] poured out his bowl on the sun. He was given the power to burn people with fire, 9 and people were burned by the intense heat. So they blasphemed the name of God who had the power over these plagues, and they did not repent and give Him glory (HCSB).
And people were burned
The fourth angel pours out his bowl on the sun, resulting in intense heat that burns people. While the first three bowl judgments are directed toward the earthly elements – namely, the earth, sea, rivers and springs of water – the fourth judgment is aimed skyward, toward the light-bearing and warmth-giving orb that interacts with the earthly elements to sustain life.
This angel, like others we have encountered, is granted authority over some part of the physical universe. In this case, he is given the power to burn people, and he uses the fusion-powered heat of the sun to carry out his task. (Some versions, it must be noted, render the word “it” rather than “he,” indicating that the sun is personified as in Ps. 19:1-6.) At its core, the sun is 27 million degrees Fahrenheit. Even the coolest part of the sun – the sun spot – is 6,700 degrees Fahrenheit, several times hotter than the lava from a volcano (www.planetfacts.org).
The earth is about 93 million miles from the sun. As the earth circles the sun in an elliptical route, the distance between the two varies from about 91 million miles to 94.5 million miles, contributing to our seasons. While that fluctuating distance seems to leave a lot of wiggle room, the fact is that if the earth passed much closer to or farther from the sun, life would be far different here, if possible at all. God created the earth and the stellar heavens to support His special creation on earth, and He holds all things together (Col. 1:17).
If the fourth bowl judgment is to be taken literally, perhaps the Lord empowers the angel to move the earth and the sun a little closer together. Or, he may simply crank up the process by which the sun generates heat. In any case, people on earth feel the impact and are burned. It appears that the people burned are those who worship the beast, for we see that they blaspheme God and refuse to repent.
