You're right, of course. The Temple was never desecrated, and is standing right where it was when our Lord's disciples asked Him about it to tis very day. Sacrifice and oblation continue there unabated. None of the disciples ever saw Jerusalem surrounded by armies, and there was never any reason to flee the city. No nation has ever risen against another nation, there have been no wars nor rumors thereof, the Church has never faced persecution, there was never any requirement for people to make sacrifice to the emperor in order to legally buy or sell, ad infinitum.
You KNOW none of those thing has happened, because preterists believe that some or all of them really have, and you KNOW that preterism both partial and full, are false.
Just out of curiousity, are you into the flat earth thing as well?
Revelation strictly concerns the mediation of Christ upon the Church, which is under the New Covenant, not the Old. This is clearly illustrated in chapter 1. As such, the “Jerusalem” in the book pertains to that of the New Covenant, the one depicted in Galatians 4:26 and Hebrew 12:22. There is no evidence in the NT, let alone the OT, that supports the destruction of Jerusalem in AD 70 warrants any interpretation that God is finished with the phenomenon of “Jerusalem” and its significance. There is merely a supplanting of the old with the new, which is the subject of the Revelation in 3:10-12 and 21:1-2. (Not unlike the destruction of Solomon’s temple being ultimately supplanted with Herod’s.) Chapter 3 affirms that the trials and tribulations upon God’s people did not end with the events of AD 70 but commenced with the NT house of God (1 Peter 4:17-18). It is the Church that represents Jerusalem now. The trial depicted in Revelation 3:10-12 is “upon all the world, to try them that dwell upon the earth,” not merely ancient Judah. The true Church is kept from the universal trail by keeping what is written in the Revelation and the commandments of God (Revelation 12:17). Again, Revelation maintains an expansion of God’s judgments upon all the world, not just ancient Jerusalem. This is why we have not entered the consummate kingdom of Christ, the stone kingdom of Daniel 2. Only when probation ends for the Church will New Jerusalem be ready for the next step to come down from heaven as Christ smites the nations, which is not until the last trump.
Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption. Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed, In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed. (1 Corinthians 15:50-52)
Corinthians, above, parallels the seventh trumpet in Revelation 11, when the dead in Christ are raised and receive their reward. The dead in Christ were not raised and caught up with the living (1 Thessalonians 4:16-17) in AD 70.
The destruction of the temple in AD 70 was a judgment under the Old Covenant and we must look to the events prophesied by those who ministered under the Old Covenant, like, take for instance, Zechariah.
There is a voice of the howling of the shepherds; for their glory is spoiled: a voice of the roaring of young lions; for the pride of Jordan is spoiled. Thus saith the LORD my God; Feed the flock of the slaughter; Whose possessors slay them, and hold themselves not guilty: and they that sell them say, Blessed be the LORD; for I am rich: and their own shepherds pity them not. For I will no more pity the inhabitants of the land, saith the LORD: but, lo, I will deliver the men every one into his neighbour's hand, and into the hand of his king: and they shall smite the land, and out of their hand I will not deliver them. I will feed the flock of slaughter, even you, O poor of the flock. And I took unto me two staves; the one I called Beauty, and the other I called Bands; and I fed the flock. Three shepherds also I cut off in one month; and my soul lothed them, and their soul also abhorred me. (Zechariah 11:3-8)
There are other OT prophets that prophesied of the destruction of ancient Jerusalem, but the Revelation is Christ’s mediation upon the seven church epochs. The seven churches represent the seven months or epochs between the spring and autumnal festivals, which by any wise account represent this age and the mediation by Christ upon his New Testament Church.
