Charles Ellicott Commentary Revelation 22:6

"And he said unto me, These words are faithful and true: and the Lord, the God of the spirits of the prophets, sent his angels to show unto his servants the things which must shortly come to pass." — Revelation 22:6 (ASV)

WORDS OF CONFIRMATION AND WARNING.

And he said to me . . .—It is the angel who speaks. (Compare Revelation 21:0 and Revelation 22:9 of this chapter.) In Revelation 22:7 we hear the words of Christ Himself.

These sayings (or, words) are faithful and true. The reference is to the whole book. The book contains the Revelation of the faithful and true witness (Revelation 3:14), whose words are faithful, trustworthy, and fulfilling the desire of them that fear Him.

Nor is there reason to doubt this; for the Lord, the God of the spirits of the Prophets—the God whose spirit moved the holy men of old to speak (2 Peter 1:21)—sent His angel to show to His servants things which must come to pass shortly. (Compare Note on Revelation 1:1.)

On verses 6-21:

These verses contain the concluding words. It is the Epilogue of the Book; it deals with practical exhortations, warnings, and blessings.
