Revelation 22:7

5 There will be no more night in the city, and they will have no need for the light of a lamp or of the sun. For the Lord God will shine on them, and they will reign forever and ever.

6 Then the angel said to me, “These words are faithful and true. The Lord, the God of the spirits of the prophets, has sent His angel to show His servants what must soon take place.”

“Behold, I am coming soon. Blessed is the one who keeps the words of prophecy in this book.”

8 And I am John, who heard and saw these things. And when I had heard and seen them, I fell down to worship at the feet of the angel who had shown me these things.

9 But he said to me, “Do not do that! I am a fellow servant with you and your brothers the prophets, and with those who keep the words of this book. Worship God!”

Do read the surrounding verses too, because the context often says more than a single verse.
