Passage
Therefore, rejoice, O heavens, and you that dwell therein. Woe to the earth and to the sea, because the devil is come down unto you, having great wrath, knowing that he hath but a short time.
Therefore, rejoice, O heavens, and you that dwell therein. Woe to the earth and to the sea, because the devil is come down unto you, having great wrath, knowing that he hath but a short time.
Revelation 12:10 And I heard a loud voice in heaven, saying: Now is come salvation and strength and the kingdom of our God and the power of his Christ: because the accuser of our brethren is cast forth, who accused them before our God day and night.
Revelation 12:11 And they overcame him by the blood of the Lamb and by the word of the testimony: and they loved not their lives unto death.
Revelation 12:12 Therefore, rejoice, O heavens, and you that dwell therein. Woe to the earth and to the sea, because the devil is come down unto you, having great wrath, knowing that he hath but a short time.
Revelation 12:13 And when the dragon saw that he was cast unto the earth, he persecuted the woman who brought forth the man child.
Revelation 12:14 And there were given to the woman two wings of a great eagle, that she might fly into the desert, unto her place, where she is nourished for a time and times, and half a time, from the face of the serpent.
The verse centers on "therefore", "rejoice", "heavens", "dwell", "therein", "earth", "devil", and "come". It is saying that the verse draws attention to "therefore" 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 by the blood..." into verse 13's "And when the dragon saw that he...", so "therefore" 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 "therefore" and "rejoice" with trust shaped by these words, not by a vague optimism outside the passage.
