Passage
And night shall not be any more, and no need of a lamp, and light of [the] sun; for [the] Lord God shall shine upon them, and they shall reign to the ages of ages.
And night shall not be any more, and no need of a lamp, and light of [the] sun; for [the] Lord God shall shine upon them, and they shall reign to the ages of ages.
Revelation 22:3 And no curse shall be any more; and the throne of God and of the Lamb shall be in it; and his servants shall serve him,
Revelation 22:4 and they shall see his face; and his name [is] on their foreheads.
Revelation 22:5 And night shall not be any more, and no need of a lamp, and light of [the] sun; for [the] Lord God shall shine upon them, and they shall reign to the ages of ages.
Revelation 22:6 And he said to me, These words [are] faithful and true; and [the] Lord God of the spirits of the prophets has sent his angel to shew to his bondmen the things which must soon come to pass.
Revelation 22:7 And behold, I come quickly. Blessed [is] he who keeps the words of the prophecy of this book.
The verse centers on "light", "night", "shall", "need", "lamp", "lord", and "shine". It is saying that the verse draws attention to "light" and "night", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 4's "and they shall see his face and..." into verse 6's "And he said to me These words...", so "light" and "night" 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 "light" and "night" with trust shaped by these words, not by a vague optimism outside the passage.
