Shared ground
The elders’ response links the seventh trumpet’s announcement (11:15) to worship and interpretation. Their posture (falling face-down) signals that God’s authority outranks all other thrones. Their thanks is not generic gratitude; it is focused on God actively taking up “great power” and beginning to reign.
The elders also connect God’s reign to public outcomes in history. The text explicitly names resistance (“the nations were angry”), divine response (“your wrath came”), and a decisive “time” that includes judging the dead, rewarding God’s people, and removing those who ruin the earth.
Where interpretation differs
“The one who is and who was” (and the missing “who is to come”). Some think the wording implies that, with the seventh trumpet, God’s long-promised coming is now arriving in action—so the title shifts because the “coming” is no longer only future. Others think it is simply a stylistic abbreviation with no special timing implied.
“The nations.” Some read “nations” as the world’s peoples in general, emphasizing a global pushback against God’s rule. Others read it more narrowly as hostile powers and regimes that oppose God, without making a claim about every individual person.
“The time for the dead to be judged.” Some take this as the final, universal judgment at the end of history. Others see it as the certainty of final judgment being announced here, even if the narrative later describes related scenes in multiple steps.
“Destroy those who destroy the earth.” Some understand “earth” mainly as the human world—societies harmed by violence, oppression, and corruption. Others also include the physical earth—real devastation of creation—since the line sounds like repayment that matches the damage done.
Why the disagreement exists
Revelation communicates through compressed, poetic summaries. In v. 18 several events are listed in a tight sequence (anger, wrath, judgment, reward, destruction), but the book as a whole presents these themes in multiple visions. Readers differ on whether v. 18 is describing a single end-point moment, or summarizing outcomes that the rest of the book will unfold in stages. Also, words like “nations” and “earth” can naturally be read broadly or more narrowly.
What this passage clearly contributes
This scene presents God’s reign as something asserted in power, not merely affirmed in worship. It frames world opposition as a predictable response to God’s rule, and it ties God’s response to moral accountability: the dead are judged, God’s servants are rewarded (prophets, saints, and all who fear God’s name—“small and great”), and those who ruin the earth face decisive removal. In other words, the elders interpret the trumpet not only as a claim of sovereignty, but as the start (or unveiling) of a settled outcome: justice, vindication, and the end of destructive forces (compare Revelation 4:10 for the elders’ recurring worship role).
