Ive heard this from numerous people, I think what they are saying is this, in the book of Job which is placed chronologically before a lot of events in the book of Genesis we know Satan had access to heaven, and therefore it proves he has access now, The problem I have with this logic is that I find it similar to this type of reasoning. Job also offered sacrifices to God So we should also offer sacrifices to God!The events of Revelation 12 have not yet occured, but they occur near the end of the world. In terms of Satan having access to heaven until then, yes, this is seen in book of Job.
We dont because we know circumstances have changed, So I would like to point out that just because people show Satan had access to heaven in the book of Job (by the way I dont think that is even the point in Job but the opposite) it does not prove in any way that he has access now.
In terms of the fallen angels it's a matter of two groups of fallen angels, one that fell in the past near the time of the Flood (thus neccessitating the Flood in part). For these angels, no, they cannot access heaven nor the Earth, because they are in chains in hell right now, expressly bound in hell and unable to go anywhere reserved in chains of darkness until the end.
I dont think Gen 6 is talking about the fallen angels, but if there is a verse that supports this notion I dont know of it and would be interested to hear it, Interesting enough there are two accounts of angels being thrown to earth in Rev 12 whether its one group or two groups is another discussion. But in Rev 12:4 The dragons tail throws a third of the stars to the earth and the timing is specific that its when the Child is Born.
This account is a picture of the one third of the angels following Satan, and being removed from their habitation,( hence they now look for habitation on earth) and end up tormenting men, this lines up with the gospel accounts and we can see numerous amounts of demonic possession throughout the Gospel accounts, and I agree that these fallen angels were cast out and are now in chains (just disagree with the timing of the fall) which is why there is currently no demon possession in this day and age.
I know some fringe people are going to say but there was demon possession at the time of Christ so that proves there's demon possession now, But its the same fallacy as people use to show that Job proves Satan has access to heaven now. Just because something has happened in the past does not make it a rule it has to keep happening.
The second group of angels that fall with Satan in the Apocalypse are to be presumed to still be in heaven and to be angels still, perhaps he has seduced some of them through time up there and some have already sided with him (based on the apostles warning that if even an angel of heaven brings a contrary Gospel than the true Gospel that they are accursed) or perhaps they will be seduced en masse close to the time of the end when Satan makes his fated futile gambit for the Throne. Either way it will be futile for Satan to make his war in the heavens and him and the angels that side with him gets flawlessly defeated, thwarted by the loyal holy angels led by Michael the archangel. When Satan and the Apocalyptic Fallen Angels are thrown down to the Earth, they will be on the Earth in those days for certain, it will not be possible to miss this event since Satan and a third of the entire angels that side with him will be openly on Earth and unable to go back up to heaven.
Think of it like this, God throws them down like a slab of meat is thrown down on to the counter to be prepared to be butchered and roasted. They won't be here long, only as long as the Man of Sin who enters a direct league with Satan himself reigns and that's only like a few years. Then Jesus returns and raising up the male virgins and with the legions of holy angels, he puts Satan's entire kingdom down. Even furthermore to boast against Satan and his stupid children eternally, Jesus and his army will even furthermore suffer zero casualties on his side, no wounded no dead in Jesus army at the last battle. Flawless victory for Jesus, the outcome called before it is has happened, and it will happen, Jesus will win, PRAISE JESUS!
Its an interesting topic for sure, I enjoy looking at your view, I want to ask heaps of questions but another time, I like how you place emphasis on the Lord Jesus, And I honestly think the Lord is even more pivotal and more central to this discussion than what a lot of people think, its interesting hearing peoples thoughts on this, you can tell where peoples positions lie in other areas like on eternal security and Calvinism from the why they think God deals with angels.
Just food for thought I dont think its coincidence that when Jesus was revealed come in the flesh as a Son of man and Son of God that the rebellion of verse 4 occurred, the angels are watching events on earth maybe they have to have faith in God to, or they would end up rejecting Gods Word, Christ come in the flesh who was dwelling among us underserving creatures. It would not be that weird that the mechanism for our salvation and eternal life could be the same mechanism for the angels would it?
