How do we know the judgment of God is coming upon the world?

God communicates His impending judgments through the trumpets in the book of Revelation. Each trumpet represents a distinct facet of divine judgment unleashed upon the world, particularly targeting those who refuse to repent from their idolatry and sins. As the passage explains, these judgments not only serve as a wake-up call to humanity but also reaffirm God's sovereignty. The consistent themes of judgment highlight that God is righteous and just, responding to the spiritual and moral decay present within the world. This aligns with the teachings in scripture about the consequences of unrepentant sin, as seen in Revelation 9:20-21.
