This relationship is made clear through a revelation given to the Church of Jesus Christ of Latter-day Saints in 1831:
"Hearken, and lo, a voice as of one from on high, who is mighty and powerful, whose going forth is unto the ends of the earth, yea, whose voice is unto men—Prepare ye the way of the Lord, make his paths straight. The keys of the kingdom of God are committed unto man on the earth, and from thence shall the gospel roll forth unto the ends of the earth, as the stone which is cut out of the mountain without hands shall roll forth, until it has filled the whole earth. . . . Call upon the Lord, that his kingdom may go forth upon the earth, that the inhabitants thereof may receive it, and be prepared for the days to come, in the which the Son of Man shall come down in heaven, clothed in the brightness of his glory, to meet the kingdom of God which is set up on the earth. Wherefore may the kingdom of God go forth, that the kingdom of heaven may come, that thou, O God, mayest be glorified in heaven so on earth, that thy enemies may be subdued; for thine is the honour, power and glory, for ever and ever. Amen." (D&C, Sec. 65).
When the Messiah comes to rule and reign, He will be accompanied by the hosts of the righteous who have already passed through the change of death; and the righteous who are yet in the flesh shall be caught up to meet Him, and shall descend with Him as partakers of His glory. Then shall the Kingdom of God on earth be made one with the Kingdom of Heaven. Then shall be realized the glorious fulfilment of the prayer taught by the Christ, and voiced by men through the ages past, Thy Kingdom come.
The Kingdom of Heaven on earth is to be a literal government, administered under the supreme direction of Jesus Christ the King. No longer shall men arrogate to themselves the power of might to exercise dominion over their fellows, nor exalt themselves on thrones, nor bedeck themselves with crowns and scepters.
That the extent and jurisdiction of the kingdom shall be world-wide was declared by Daniel to Nebuchadnezzar, depicting "what shall be in the latter days." Thus spake the prophet:
"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. Forasmuch as thou sawest that the stone was cut out of the mountain without hands, and that it brake in pieces the iron, the brass, the clay, the silver, and the gold; the great God hath made known to the king what shall come to pass hereafter: and the dream is certain, and the interpretation thereof sure." (Dan. 2:44-45; see also verse 28).
