because of this be glad, ye heavens, and those in them who do tabernacle; woe to those inhabiting the land and the sea, because the Devil did go down unto you, having great wrath, having known that he hath little time.'
Revelation 12:10 And I heard a great voice saying in the heaven, `Now did come the salvation, and the power, and the reign, of our God, and the authority of His Christ, because cast down was the accuser of our brethren, who is accusing them before our God day and night;
Revelation 12:11 and they did overcome him because of the blood of the Lamb, and because of the word of their testimony, and they did not love their life--unto death;

The verse centers on "glad", "heavens", "tabernacle", "inhabiting", "land", "devil", "down", and "having". It is saying that the verse draws attention to "glad" and "heavens", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 11's "and they did overcome him because of..." into verse 13's "And when the dragon saw that he...", so "glad" and "heavens" 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 "glad" and "heavens" with trust shaped by these words, not by a vague optimism outside the passage.
