The end of time is coming soon. The signs are everywhere. God gives us signs in the heavens and even during the tribulation period, He is using the sun, moon, and stars for His purpose. He is so merciful and gives man every possible chance to repent.
According to the Book of Revelation, chapter 16, the sun will be so glaring down on men (much worse than the eclipse) that they will be scorched with fire and a fervent heat. Despite this plague upon men by the fourth angel who poured out his vial, men continued to blaspheme God’s name with their glaring tongues. And after the fifth angel poured out his vial, men were gnawing their tongues because of the pain but yet, they still refused to repent and continued to blaspheme God.
And by the time the seventh angel poured out his vial into the air, there was a great voice from the throne of heaven saying “It is done.” Then there was such a great earthquake that every island disappeared along with the mountains, and great hail fell out of heaven. Even still, men blasphemed God.
