This will take the place of all earthly kingdoms.
The Kingdom will not only have a visible dominion across the entire planet, it will also have a divine-political dominion superseding all other
kingdoms.

"And in the days of these kings shall the God of heaven set up a kingdom, which shall never be destroyed: and the kingdom
shall not be left to other people, but it shall break in pieces and consume all these kingdoms, and it shall stand for ever."
(Dan.
2:44)

"I saw in the night visions, and, behold, one like the Son of man came with the clouds of heaven, and came to the Ancient of
days, and they brought him near before him.
14  And there was given him dominion, and glory, and a kingdom, that all people, nations, and languages, should serve him: his
dominion is an everlasting dominion, which shall not pass away, and his kingdom that which shall not be destroyed."
(Dan.
7:13-14)

"And the LORD shall be king over all the earth: in that day shall there be one LORD, and his name one." (Zech. 14:9)

Jesus Christ Himself will be the supreme Theocratic King over the universe.

"And the seventh angel sounded; and there were great voices in heaven, saying, The kingdoms of this world are become the
kingdoms of our Lord, and of his Christ; and he shall reign for ever and ever."
(Rev. 11:15)

This isn't the Church, it is not taking over the world but the world is taking over the Church. The Kingdom at one time was visible on the
earth, but in man's rebellion was rejected and overthrown. God has promised it will be restored under David's Son, which is Christ Jesus
our Lord.

"For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be
called Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace.
Of the increase of his
government and peace there shall be no end
, upon the throne of David, and upon his kingdom, to order it, and to establish it
with judgment and with justice from henceforth even for ever. The zeal of the LORD of hosts will perform this."
(Isa. 9:6,7)

When this Kingdom is restored as covenant and promises declare, then this political rule will
also be restored; this time covering the
entire world under the Kingship of Jesus.

Fairbairn (On Prophecy p. 297), when alluding to the language of Daniel respecting the Kingdom, he says, it is such as "to indicate an
actual remodelling
of the state of things among men, and a fresh organization of the social fabric such as would formally commit the
administration of affairs into the hands of the Lord's people
," and he admits (p. 465) that this includes "the formal elevation of the
pious and God-fearing portion of mankind
to the place of influence and authority."

So far, we should realize:
1) The word of God demands such an outward dominion, as the verses quoted point out.
2) This kingdom will be supreme over the entire earth; even to the entire universe.
3) The want for this Kingdom is felt and acknowledged by those Christians who sincerely love and look for Christ and His coming again.
4) The hope is expressed that it will finally, in some way, be realized. This is not done on our time table, nor by our doing, but in God's time;
only accomplished by Him. ("Thy Kingdom come, Thy will be done...") It is not a political body of human institution.
It has a divine origin
founded in its covenanted relationship (through the Abrahamic/Davidic covenants).

The Theocratic Kingdom once existed when God ruled the earth directly during the time of the patriarchs, or through the time of the judges
by speaking through the judges or prophets at that time. When the Jews rejected God and demanded a king God still ruled through the
earthly king but eventually withdrew the Theocracy when sin grew too much and God left them to their wicked ways (this is recorded in
Isaiah). This visible, external Kingdom will once again exist when God condescends to act as earthly Ruler in and through and by David's
Son (Jesus Christ).

This is definitely a
Theocracy; the Rulership is safely and powerfully lodged in one Person, who in Himself unites the human and the Divine,
who becomes, according to "the everlasting covenant" and "the sure mercies of David"
(Isa. 55:3,4), "a leader and commander to the
people
."
The Kingdom of God will be a visible,
external one here on the earth.
