The death, resurrection and ascension of Christ marked the end of the Old Covenant and the beginning of the New; the apostles were commissioned to deliver Christ’s message in the form of the New Testament; and when they were finished, God sent the Edomites and the Roman armies to destroy utterly the last remaining symbols of the Old Covenant: the Temple and the Holy City. This fact alone is sufficient to establish the writing of the Revelation as taking place before A.D. 70. The book itself gives abundant testimony regarding its date; but, even more, the nature of the New Testament as God’s Final Word tells us this. Christ’s death at the hands of the apostate children of Israel sealed their fate: The Kingdom would be taken from them (Matt. 21:33-43). While wrath built up “to the utmost” (1 Thess. 2:16), God stayed His hand of judgment until the writing of the New Covenant document was accomplished. With that done, He dramatically terminated the kingdom of Israel, wiping out the persecuting generation (Matt. 23:34-36; 24:34; Luke 11:49-50. Jerusalem’s destruction was the last blast of the trumpet, signalling that the “mystery of God” was finished (Rev. 10:7). There would be no further canonical writings once Israel was gone.

He does not provide any fact other than it fits with his doctrine. Yes, the book of Revelation does give ample evidence saying he was exiled to Patmos, that was a standard punishment of Domitian. He does not even attempt to address the fact that all of the church fathers say it was written at the end of Domitians reign. Sorry, this is clownish.
