Hi folk - thanks John for an interesting topic.
I've been aware of this thread & seen a few posts, & now it's a bit late to join it, but here goes ....
I think there are three time periods relevant -
1. The time prior to the destruction:
John, like Paul in 2 Thes. 2, & Peter in 2 Peter 3, was warning people of his own generation -
this generation - to watch out for antichrists who were trying to gather support for their rebellion/apostasy leading up to AD 70.
Those antichrists, & the antichrist/man of sin perished.
2. Throughout the Gospel age:
But all these things are written for general instruction for the church down the ages. There have been plenty of antichrists, rising up in power, & perishing. Many have been named in the thread.
Perhaps the most dangerous of these was Constantine who, with the connivance of the Bishops "Christianised" the Empire, so that church & state became one entity with two arms, two swords - word & steel, to control the world.
True Christians, Donatist, Anabaptists, & others maintained their witness as a persecuted minority.
Rome fell, but the antichristian RC church retained its authority by associating with whoever had military power.
And the Reformers continued with that church-state association & continued to persecute the Anabaptists & other non-conformists.
3. At the end of time:
How will living Christians recognise him? That is what this thread is all about. There have been many antichrists in history, & they have been identified at the time. I think, though, none fit the prophetic description - but will HE? Not if he died in AD 70 & we are looking for powerful & evil men who are antichrist, but not THE antichrist.
I think the focus on the nation of Israel in the land promised to Abram could be significant, but I consider the restoration prophecies were fulfilled by Christ & the many thousands of Israelites who formed the church after Pentecost. IMO the present nation is not relevant to prophecy.
Christians should always be aware of antichrists, but I do not consider the futurists who have gained the popularity over the last 70 years are better at guessing than the rest of us.
So, what did Jesus say?
Mark 13:31 Heaven and earth will pass away, but my words will never pass away.
32 ‘But about that day or hour no one knows, not even the angels in heaven, nor the Son, but only the Father. 33 Be on guard! Be alert! You do not know when that time will come. 34 It’s like a man going away: he leaves his house and puts his servants in charge, each with their assigned task, and tells the one at the door to keep watch.
35 ‘Therefore keep watch because you do not know when the owner of the house will come back – whether in the evening, or at midnight, or when the cock crows, or at dawn. 36 If he comes suddenly, do not let him find you sleeping. 37 What I say to you, I say to everyone: “Watch!”’
