5 He who sits on the throne said, “Behold, I make all things new.” He said, “Write, for these words are faithful and true.”
And He who sits on the throne – see also Rev 4:2, Rev 5:1, the Spirit of Christ, again, appears as the image of the invisible God on the throne.
Write, for these words are faithful and true – the Spirit of Christ, speaking as the Archangel, again asks John to “write.” See Rev 19:9 “Write…these are the true words of God.”
