Saying the events occurred in 70 AD is mpreterism & is totally-false. The earth went right on in 71 AD same as it did in 65 AD.
Scripture says, in Rev. 20:6 Blessed and holy is he who has part in the first resurrection. Over such the second death has no power, but they shall be priests of God and of Christ, and shall reign with Him a thousand years.
Just before that, Satan shall be banished to "the abyss" for that m1K years. And when the 1K years are up, God says this shall happen: Rev. 20:7 Now when the thousand years have expired, Satan will be released from his prison 8 and will go out to deceive the nations which are in the four corners of the earth, Gog and Magog, to gather them together to battle, whose number is as the sand of the sea. 9 They went up on the breadth of the earth and surrounded the camp of the saints and the beloved city. And fire came down from God out of heaven and devoured them.
So we see Scripture DEFINITELY says the millenium will occur, and to say otherwise is simply denying God's word ! ! And we see there'll still be mortals on earth during that time, but the saints will be with Jesus in Jerusalem (the beloved city) and Jesus shall rule the world with a rod of iron(Rev. 2:27, 12:5, 19:15)
There's simply NO legitimate, nor truthful, denying the millenium shall come shortly after Jesus' return. nThose Scriptures make lies outta all the preterist claims that those events have already occurred, or that they're anything else besides what Scripture plainly says they are. I summarily reject any claims otherwise as they simply don't jive with Scripture.
