I agree that only because of Jesus can we ever be near God`s holy presence. However, I don`t believe we will `see` God the Father as He is Spirit.
Now, would you agree that the New Jerusalem comes down out of heaven FROM God, so therefore God the Father will still be in the highest heaven?
And the throne that is in the New Jerusalem will be His power and authority, and His dwelling with men will be by His Holy Spirit?
All of those are good questions. I think that by now you know that I am a Bible person and teach it in a literal fashion.
So, will wee see God face to face in heaven is what you are asking.
IMHO and in MY understanding of the Scriptures I say
YES.
In Matthew 5:8 God said.......
“Blessed are the pure of heart,
for they shall see God.”
The apostle Paul writes in 1 Corth. 13:12..........
“For now we see in a mirror dimly,
but then face to face”.
From those Scriptures I am convinced that In heaven, we’ll be in the presence of the Lord, and we’ll see him face to face.
My favorite verse about seeing God is 1 John 3:2.........
“Beloved, we are God’s children now, and what we will be has not yet appeared; but we know that when he appears,
we shall be like him, because we shall see him as he is.”
Honestly, I do not know how that can be debated.
Then you asked if God the Father would be in New Jerusalem or stay in heaven's highest place?
Again, relying only on the Scriptures in Revelation 21:2 and also vs. 10 I see that New Jerusalem comes down out of heaven from God.
Then in 2 21:3 God tells us that after it descends from heaven
“the dwelling of God is with men, and he will live with them. They will be his people, and God himself will be with them and be their God.”
We also understand that there was also no temple in the New Jerusalem city because God and the lamb (Christ) are its temple (21:22).
God’s throne is in the city and his people will see his face in 22:3-4.
The Greek word for “people” is plural “Peoples.” God’s people in the New Jerusalem are multi-ethnic.
