Let's read that from the beginning in Luke 11: 17 But he, knowing their thoughts, said unto them, Every kingdom divided against itself is brought to desolation; and a house divided against a house falleth. 18 If Satan also be divided against himself, how shall his kingdom stand? because ye say that I cast out devils through Beelzebub. 19 And if I by Beelzebub cast out devils, by whom do your sons cast them out? therefore shall they be your judges.
20 But if I with the finger of God cast out devils, no doubt the kingdom of God is come upon you. This is not talking about Jesus physical kingdom, he's talking about word of God, which is himself. The rest of it explains itself.
Lets go read about the first one in Revelation 20:4 And I saw thrones, and they sat upon them, and judgment was given unto them: and I saw the souls of them that were beheaded for the witness of Jesus, and for the word of God, and which had not worshipped the beast, neither his image, neither had received his mark upon their foreheads, or in their hands; and they lived and reigned with Christ a thousand years. 5 But the rest of the dead lived not again until the thousand years were finished. This is the first resurrection. Pay attention to what you reading, this is a thousand years with Christ on Earth!
Now Let"s look at the next Kingdom after Christ. Revelation 21: 1 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. 2 And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband. 3 And I heard a great voice out of heaven saying, Behold, the tabernacle of God is with men, and he will dwell with them, and they shall be his people, and God himself shall be with them, and be their God. 10 And he carried me away in the spirit to a great and high mountain, and shewed me that great city, the holy Jerusalem, descending out of heaven from God, 22 And I saw no temple therein: for the Lord God Almighty and the Lamb are the temple of it. 23 And the city had no need of the sun, neither of the moon, to shine in it: for the glory of God did lighten it, and the Lamb is the light thereof.
Two different Kingdoms and time periods on earth. You have to really read the Book from Genesis to Revelation. Jesus came preaching the Gospel, Jesus says in Matthew 24: 13 But he that shall endure unto the end, the same shall be saved. 14 And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come.
This is my gift to you. It proves what I said is true.
Please consider the spiritual nature of the Kingdom:
