This Trumpet of the angel from the Euphrates is described at the end of Revelation 7:13 as ‘woe’ to the earth. Don’t confuse this 6th trumpet with the Last Trump of 1 Cor.15:55, which is the Trump of God (1 Thess.4:16). God’s trumpet call will not be ‘woe’ but ‘wonderful’; a call to the Bride of Christ at the Rapture of the Church. This will be the Last Trumpet from God (Rev.4:1) before the wrath and judgment. Remember, here in Rev. 9, we are reading of things future (Rev.1:19). This judgment is coming from the mercy seat of the Golden Altar which stands before God. The God of mercy and Love is bringing wrath upon the Christ rejecting people of earth. In Genesis 6 God said; “My Spirit shall not always strive with man..” through Noah God warned people of the impending flood. And just as Noah found grace in the eyes of the Lord, so have we. We are the Bride of Christ, and we are also warning this Christ-rejecting world of the judgment as we point them to Jesus Christ for salvation.
