Hi Booker,
The Kingdom of God/Heaven are one in the same. It is the abode/mind of God in perfect goodness, holiness and truth. It is not a place, but a spiritual realm.
Your identity is your mind that produce thoughts, attitudes, behavior, intellect, awareness, reason, ideas and memory that come into our awareness from our experiences/life. This is an invisible realm, it's our inner awareness/personality... our heaven. When we begin to learn the knowledge of the truth, we are developing the mind of God, the process of being made into His image.
Luke 17:21 nor will they say, "See here!' or "See there!' For indeed,
the kingdom of God is within you."
Here is a section from the article 'The Lucifer Hoax and the Mission of Satan.'

GOD’S HEAVEN IS HIGHER THAN MAN’S HEAVEN
Satan is the god of this world (I Cor. 4:4). Satan possesses ALL the kingdoms of the world (Matt. 4:8-9). Satan appears to the heads of his nations as an angel of light (I Cor. 11:12). It was Satan who appealed to the heaven of Eve’s mind. It was Satan that caused the people to build a tower that would reach MAN’S concept of heaven. The heaven of the minds of those conceiving of such lofty things. It was Satan who caused the king of Babylon to be lifted up in his own heaven, his own mind. Listen to his own words:
"At the end of twelve months he walked in the palace of the kingdom of Babylon. The king spake, and said, is not this GREAT BABYLON, that I have built for the house of the kingdom by the might of MY power, and for the honour of MY MAJESTY?"
v
God has a heaven. It is a SPIRIT REALM. It is where God lives and has His Being. Men too have a heaven. It is likewise, the REALM where they live and have their being—they spiritually live in their own minds, their own heavens.
Notice Prov. 23:7, "For as he THINKS in his heart, SO IS HE." The ‘heart’ is the innermost seat of our deepest emotions, but it is accessed through the MIND. It is what one thinks that determines what one is. When the king of Babylon THOUGHT that he had ascended into heaven in his mind, then that is where HE WAS, "so IS he." But ... BUT, it was man’s heaven and not God’s. No ‘man,’ no ‘carnal man’ has ever ascended into God’s heaven of spirit,
"And NO MAN has ascended up to heaven [God’s heaven], but He that came down from heaven, even the Son of man WHICH IS IN HEAVEN [right at the very time He was speaking these words]" (John 3:13).
Jesus could live "on earth" and "in heaven" at the same time! But carnal men live in the heaven of their minds all the time. Man’s heaven is a place of spiritual delusion; whereas God’s heaven is a place of spiritual enlightenment.
"And I saw a great white throne, and Him that sat on it, from whose face the EARTH [of man] and the HEAVEN [of man] fled away; and there was found NO PLACE FOR THEM… And whosoever was not found written in the book of life was cast into the lake of fire. And I saw a NEW heaven and a NEW earth: for the first heaven and the first earth were passed away; and there was no more sea." (Rev. 20:11, 16 & 21:1).
It would be mind-boggling enough to think that the entire UNIVERSE could "flee away," but it would be quite another to then suggest that, "there was found NO PLACE FOR THEM." That would be absurd if taken literally. ALL THESE THINGS ARE SPIRITUAL! In the white throne judgment there will be no more a place for the flesh, for the carnal mind, for man’s heaven. There will truly be no place found for them. They will be annihilated in God’s "CONSUMING FIRE" (Heb. 12:29 & I Cor. 3:15)!
God will give man a new earth and a new heaven, and as for the great sea of carnal, God-defying humanity, "…and there was NO MORE SEA."
