And he said unto me, These words are faithful and true: and the Lord God of the holy prophets sent his angel to show unto his servants the things which must shortly be done. Behold, I come quickly: blessed is he that keeps the sayings of the prophecy of this book.

And I John saw these things, and heard them. And when I had heard and seen, I fell down to worship before the feet of the angel who showed me these things. Then he said unto me, See you do it not: for I am your fellow servant, and of your brethren the prophets, and of them who keep the words of this book: worship God. (Revelation 22:6-9)
