Also look at the possibility that Satan fell when he caused man to fall. We are given no "time" as to when Satan rebelled against God...but leading man from God's path is a sure fire example of rebellion.
Also something to note is that Satan did have access to heaven before Christ. But it apparently is not open access, any time we see Satan in heaven, it is because he was summoned.
please see my post above....you are correct that we are given no time for his fall because he was not created a holy angel, but created as the evil angel of darkness, to do what he does, and his reward is to torment the wicked and unrepentent in the Lake of Fire forever. "He" is an entire host of evil angels in heaven, and there is one chief of them.
They will torment the fallen angels and the unrepentant souls -in their own unregenerated bodies- of the Adam race forever, in their kingdom of darkness, which kingdom is the "second death". The Adam persons who are rejects and cast there are the "never dying worms" who can never be transformed to sons of God for the glory again, because they are cast there soul in body, minus the dead Adam spirit of their being. that is the Teaching of the Word on that which is first laid in the Book of Enoch, and carried through Torah to Revelation.
The evil spirits on earth are the demons, who do the same, as the evil spirits in heaven do, and they serve the satans while they roam earth as disembodied spirits of the offspring of the fallen angels and daughters of Adam, and they do this by God's authority until they are gathered by the holy angels at the return of the LORD of lords and King of kings, when He sends His holy angels to gather them as the tares not planted by Him, in the earth, and they are cast into the Lake of Fire, where they will be tormented forever forever by the satans.
The satans are the created evil spirits in heaven. They are created to do what they do, for the purpose of trying/testing the holy angels in heaven and the Adam creation on earth. They have one chief, the Prince of Darkness, and his kingdom is the Lake of Fire.
They get to do it til the tribulation, when the saints go up, they come down, and the "pillars of heaven are reset", as Psalm 75:2,3 in the Hebrew states. Their place is not found in heaven anymore, and they no longer appear before the throne to accuse the sons of Adam on earth -nor are angels falling in heaven. But they do not willingly come down [for the short time before they are locked in Sheol before the letting out of there at the end of the thousand years. They are let out to try and test the seed of the "Blessed of YHWH" who are born on earth in the millennial Sabbath of earth's Peace.
This is all in the Word.
Satan is not a fallen angel, and the only person cast out of Eden, in the third heaven, is Adam. Adam is spirit, soul, and body, and the Adam spirit died irrevocably and the flesh was defiled irrevocably the day he ate the fruit of the tree of knowledge of good and evil -it wasn't an apple, either.
It is a myth that satan is a fallen angel.
It is a myth that the fruit was an apple.
Everything God created is centered right here on this earth, and the entire heavens are stretched out from this earth, when it was just a globe of [pregnant, unformed elements, -so to speak] waters, with the firmament encircling the globe.
That is what the Record God Himself wrote, as the "Scripture of Truth in heaven" [Daniel 10:21, mentions it as established fact, and Enoch wrote of reading it in heaven], which copy Adam wrote came down to Moses from Adam, through the Patriarchs.
Adam made the record of it on earth, after the fall, when he was cast out from heaven above, in the third heaven, where Paradise is. Moses did not invent the Genesis record out of mystic, vague myths, but he had copies of the writings of the Patriarchs, beginning with that whihc Adam left of the record he had from being in Paradise above, before the fall.
Paradise is in the third heaven, stretched out from earth on day 2, and Adam was "raptured" to there from the earth to reign there, with the holy angels, and to multiply the seed in his loins as building stones to build the temple not made with hands for the Glory to indwell, and thereby to to "Plant the heavens", which Adam will never do, since the death of the Adam spirit and defilment of the Adam flesh.
God's word teaches in the Living Oracles that an earthen vessel, once defiled, can never be made clean for use as a holy vessel again. Hggai 2 also shows the laying of the Foundation Stone for the second Temple not made the hands, since the first [Adam] is defiled.
Adam was made "Adam, son of God", and a "prince" over earth, and his entire kingdom was given over to Corruption =to the satan/evil spirit, and Death -another satan/ evil spirit, when he fell.
God's plan goes on, but in the New Man name.
