Passage
And a great sign was seen in the heaven, a woman arrayed with the sun, and the moon under her feet, and upon her head a crown of twelve stars,
And a great sign was seen in the heaven, a woman arrayed with the sun, and the moon under her feet, and upon her head a crown of twelve stars,
Revelation 12:1 And a great sign was seen in the heaven, a woman arrayed with the sun, and the moon under her feet, and upon her head a crown of twelve stars,
Revelation 12:2 and being with child she doth cry out, travailing and pained to bring forth.
Revelation 12:3 And there was seen another sign in the heaven, and, lo, a great red dragon, having seven heads and ten horns, and upon his head seven diadems,
The verse centers on "great", "sign", "seen", "heaven", "woman", "arrayed", "moon", and "under". It is saying that the verse draws attention to "great" and "sign", so its meaning should be read from those terms before moving to application.
The next verse adds "and being with child she doth cry...", so "great" and "sign" should be read forward into that movement. In Revelation context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "great" and "sign" with trust shaped by these words, not by a vague optimism outside the passage.
