Your beliefs are noted, but I give Scriptural support for my beliefs (though I admit my opinions could still be wrong).
I have quoted plenty of scripture, read post 15. You have not provided scripture defending how you believe that Jude 6 is addressing the Nephilim. Can you explain your reasoning for such a belief? I have asked this before because others state the same, but I have not gotten an explanation to it.
Do you acknowledge that there is a spiritual realm on earth?
I don't know what this means.
It means there are angels around us in a spiritual realm, Ephesians 6:11-12. We have guardian angels around us that protect us. Satan and his angels protect people like say Hitler and fight against us. 2 Kings 6:17 This struggle is not in heaven, highest heaven where God the Father is. The Lord's Prayer teaches that God the Father is in heaven and that in heaven his will is being done, not Satan's.
That he commands and leads the angels in battle against Satan?
Either Jesus or Michael.
Joshua 5 says the Son of God/Jesus commands the angels.
Revelation 19:11-21 has imagery of Jesus going to battle with the angels/armies of heaven against Satan.
I do not believe God the Father allows anything impure in his presence. Not even Moses could see his face, let alone Satan. When Satan goes to God, it is not in the highest heaven, but in the heavenly/spiritual realm on earth.
Besides Ex 33:12-23, Revelation 21:27 teaches that in the new age where heaven is joined with earth, there will be nothing impure. I believe people in this fallen state can not see God in all his glory. It would be too much for us and anything impure is not allowed in his presence. This will be even greater for us then at first creation.
As for your point 7, I can't see the chapter as future. The last verse states exactly where the Christian Church is today, where Satan is at war with "those who keep God’s commands and hold fast their testimony about Jesus".
There is plenty of scripture that says Satan is the prince of this world. I can't see anything in the NT that says he is still in heaven.
John 12:31 Now is the time for judgment on this
world; now the
prince of this
world will be driven out.
John 14:30 I will not say much more to you, for the
prince of this
world is coming. He has no hold over me,
John 16:11 and about judgment, because the
prince of this
world now stands condemned.
