Passage
For this reason, rejoice, O heavens and you who dwell in them. Woe to the earth and the sea, because the devil has come down to you, having great wrath, knowing that he has only a short time.”
For this reason, rejoice, O heavens and you who dwell in them. Woe to the earth and the sea, because the devil has come down to you, having great wrath, knowing that he has only a short time.”
Revelation 12:10 Then I heard a loud voice in heaven, saying, “Now the salvation, and the power, and the kingdom of our God and the authority of His Christ have come, for the accuser of our brothers has been thrown down, he who accuses them before our God day and night.
Revelation 12:11 And they overcame him because of the blood of the Lamb and because of the word of their witness, and they did not love their life even to death.
Revelation 12:12 For this reason, rejoice, O heavens and you who dwell in them. Woe to the earth and the sea, because the devil has come down to you, having great wrath, knowing that he has only a short time.”
Revelation 12:13 And when the dragon saw that he was thrown down to the earth, he persecuted the woman who gave birth to the male child.
Revelation 12:14 But the two wings of the great eagle were given to the woman, so that she could fly into the wilderness to her place, where she was nourished for a time and times and half a time, from the presence of the serpent.
The verse centers on "reason", "rejoice", "heavens", "dwell", "earth", "devil", "come", and "down". It is saying that the verse draws attention to "reason" and "rejoice", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 11's "And they overcame him because of the..." into verse 13's "And when the dragon saw that he...", so "reason" and "rejoice" belong inside that flow. In Revelation context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "reason" and "rejoice" with trust shaped by these words, not by a vague optimism outside the passage.
