That being said…
The Mystery of what the the Kingdom of the Messiah would really be like has been reveiled.
**
He said to them in reply, "Because knowledge of the mysteries of the kingdom of heaven has been granted to you, but to them it has not been granted. To anyone who has, more will be given and he will grow rich; from anyone who has not, even what he has will be taken away. This is why I speak to them in parables, because ‘they look but do not see and hear but do not listen or understand.’ Isaiah’s prophecy is fulfilled in them, which says: ‘You shall indeed hear but not understand you shall indeed look but never see. Gross is the heart of this people, they will hardly hear with their ears, they have closed their eyes, lest they see with their eyes and hear with their ears and understand with their heart and be converted, and I heal them.’ "But blessed are your eyes, because they see, and your ears, because they hear. Amen, I say to you, many prophets and righteous people longed to see what you see but did not see it, and to hear what you hear but did not hear it. (Mt 13:11-17)**
It is not a physical, political, conquering power. It is an interior kingdom in which Christ lives within the lives and hearts of men and women all over the world. For this reason, it will never be defeated or uprooted, as Daniel had foretold in his vision of the statue and the beast. Because it is a spiritual rule, no unbeliever would be able to enter it, as Zechariah stated. Jesus emphasized to an unbelieving Pilate that His was a spiritual Kingdom.
Jesus answered, “My kingdom does not belong to this world. If my kingdom did belong to this world, my attendants (would) be fighting to keep me from being handed over to the Jews. But as it is, my kingdom is not here.” So Pilate said to him, “Then you are a king?” Jesus answered, “You say I am a king. 16 For this I was born and for this I came into the world, to testify to the truth. Everyone who belongs to the truth listens to my voice.” (John 18:36-37)
His Kingdom is literally not of this present age, He sits at God’s right Hand until the time of the Father, Jesus will rule from Jerusalem in the Kingdom in Israel and over all the earth, and then after the events of what happens at the end of the 1000 year reign in Revelation 20:7-10, Jesus will hand the Kingdom over to the Father.
Pslam 110:1-7
The LORD says to my Lord:
“Sit at my right hand
until I make your enemies
a footstool for your feet.”
The LORD will extend your mighty scepter from Zion;
you will rule in the midst of your enemies.
Your troops will be willing
on your day of battle.
Arrayed in holy majesty,
from the womb of the dawn
you will receive the dew of your youth.
The LORD has sworn
and will not change his mind:
“You are a priest forever,
in the order of Melchizedek.”
The Lord is at your right hand;
he will crush kings on the day of his wrath.
He will judge the nations, heaping up the dead
and crushing the rulers of the whole earth.
He will drink from a brook beside the way;
therefore he will lift up his head.
**Zechariah 14:1-21
A day of the LORD is coming when your plunder will be divided among you.
I will gather all the nations to Jerusalem to fight against it; the city will be captured, the houses ransacked, and the women raped. Half of the city will go into exile, but the rest of the people will not be taken from the city.
Then the LORD will go out and fight against those nations, as he fights in the day of battle. On that day his feet will stand on the Mount of Olives, east of Jerusalem, and the Mount of Olives will be split in two from east to west, forming a great valley, with half of the mountain moving north and half moving south. You will flee by my mountain valley, for it will extend to Azel. You will flee as you fled from the earthquake in the days of Uzziah king of Judah. Then the LORD my God will come, and all the holy ones with him.
On that day there will be no light, no cold or frost. It will be a unique day, without daytime or nighttime—a day known to the LORD. When evening comes, there will be light.
On that day living water will flow out from Jerusalem, half to the eastern sea and half to the western sea, in summer and in winter.
The LORD will be king over the whole earth. On that day there will be one LORD, and his name the only name. …
…This is the plague with which the LORD will strike all the nations that fought against Jerusalem: Their flesh will rot while they are still standing on their feet, their eyes will rot in their sockets, and their tongues will rot in their mouths. On that day men will be stricken by the LORD with great panic. Each man will seize the hand of another, and they will attack each other. Judah too will fight at Jerusalem. The wealth of all the surrounding nations will be collected—great quantities of gold and silver and clothing. A similar plague will strike the horses and mules, the camels and donkeys, and all the animals in those camps.
Then the survivors from all the nations that have attacked Jerusalem will go up year after year to worship the King, the LORD Almighty, and to celebrate the Feast of Tabernacles. If any of the peoples of the earth do not go up to Jerusalem to worship the King, the LORD Almighty, they will have no rain. If the Egyptian people do not go up and take part, they will have no rain. The LORD will bring on them the plague he inflicts on the nations that do not go up to celebrate the Feast of Tabernacles. This will be the punishment of Egypt and the punishment of all the nations that do not go up to celebrate the Feast of Tabernacles.
On that day HOLY TO THE LORD will be inscribed on the bells of the horses, and the cooking pots in the LORD’s house will be like the sacred bowls in front of the altar. Every pot in Jerusalem and Judah will be holy to the LORD Almighty, and all who come to sacrifice will take some of the pots and cook in them. And on that day there will no longer be a Canaanite in the house of the LORD Almighty.
1 Corinthians 15:24
Then the end will come, when he hands over the kingdom to God the Father after he has destroyed all dominion, authority and power.**
At this time, yes, the Kingdom is in the hearts of His chosen ones. But this in no way goes against what God had planed for a literal Kingdom on this earth, ruled by His Son, Jesus.
Everything in prophecy that is to be restored and fulfilled before the New Heavens and earth, will be done by Jesus Christ.
