Revelation 16
These vials are bowls of the judgement of God! Sores, oceans to blood, fresh water to be as the blood of a dead man, people scorched by the sun, darkness around the beasts throne, Euphrates river dries up , and a large earthquake greater than any ever seen before. There were also hailstones weighing 100 pounds each . What else is there to say??? It's devastation like the world has never seen before and though this seems awful. It appears to give man another chance to repent. 16:9 "They were scorched by the fierce heat, and they cursed the name of God who had power over these plagues. They did not repent and give him glory."
