What does the Bible say about the seven trumpets in Revelation?

In Revelation, the seven trumpets represent divine judgments that prepare the earth for the eventual Day of Judgment. Each trumpet blast brings forth calamities, reminiscent of the plagues of Egypt, highlighting God's sovereignty and righteous judgment over both the physical creation and the unsealed. Through these trumpets, we recognize the severity of God's discipline on a sinful world while also seeing God's mercy in not fully destroying creation. They serve both as warnings to the wicked and as reminders of hope and salvation for the sealed ones in Christ.
