The Fourth Bowl of God's wrath / plague (Rev 16:8-9):
1. Poured onto the sun, and the sun scorched with fierce heat.
2. People blasphemed the name of God, and they did not repent so as to give Him glory.
3. Increasing the heat of the sun to "scorching" critically exacerbates the problem of scarce
safe water for any use (i.e. agriculture, industry, etc.) as well as massive wildfires. The First Trumpet
already burned up 1/3 of the earth (Rev 8:7).
