Lord Jesus gave 2 perspectives in His Word about His Kingdom.
Lord Jesus contrasted the Kingdom in one sense as having come, but in another sense that it would come sometime in the future. We as believers are to know the difference in that. And it's easy to know, because His written Word makes it plain... one just has to 'think'.
Matt 12:28
28 But if I cast out devils by the Spirit of God, then the kingdom of God is come unto you.
KJV
How did Jesus cast out those devils at His 1st coming? By the
"Spirit of God". He was thus referring to the Kingdom manifested by The Holy Spirit.
Luke 10:9
9 And heal the sick that are therein, and say unto them, "The kingdom of God is come nigh unto you."
KJV
How are the sick healed by Christ's disciples? By The Holy Spirit.
Luke 17:20-21
20 And when He was demanded of the Pharisees, when the kingdom of God should come, He answered them and said, "The kingdom of God cometh not with observation:
21 Neither shall they say, 'Lo here! or, lo there!' for, behold, the kingdom of God is within you.
KJV
How... is the
"kingdom of God" within us believers on Jesus Christ? In what sense did He mean that? And that word in the Greek for "
within" does mean 'inside', and not some other idea like near or within a certain time. No, Jesus meant a location with that "
within". Per Hebrews 4:12 we learn God created us with 3 parts, a spirit, a soul, and flesh and bones. His Kingdom is of The Spirit. And especially at Jesus' 1st coming, 'within' believers, literally, is where the Kingdom is, by The Spirit.
But the time will come when Jesus returns, and the Kingdom will manifest literally, here on earth in the physical. And it means the Heavenly is going to be revealed right here, on earth, with God's Kingdom here, literally, on this earth, and The Father even returning back to this earth to live here with us.
Luke 21:29-33
29 And he spake to them a parable; Behold the fig tree, and all the trees;
30 When they now shoot forth, ye see and know of your own selves that summer is now nigh at hand.
31 So likewise ye, when ye see these things come to pass, know ye that the kingdom of God is nigh at hand.
32 Verily I say unto you, This generation shall not pass away, till all be fulfilled.
33 Heaven and earth shall pass away: but my words shall not pass away.
KJV
Jesus refers above to the coming of the Kingdom in the final generation on earth that will 'see' those Signs He gave there in His Olivet discourse. The final Sign He gave there is that of His still future coming to gather His saints. That's how we know He was speaking of the future in the above. So WHICH Kingdom was He pointing to in the above, to the Kingdom by The Spirit, or to the Kingdom that will eventually manifest here on earth in the physical with His literal return to live with us? Jesus was pointing to the latter Kingdom idea.
Luke 22:18
18 For I say unto you, I will not drink of the fruit of the vine, until the kingdom of God shall come.
KJV
Which Kingdom idea is the above about? It is about the coming of His future Kingdom in the physical, with His literal return.
Matt 7:21-23
21 Not every one that saith unto Me, 'Lord, Lord', shall enter into the kingdom of heaven; but he that doeth the will of My Father Which is in heaven.
22 Many will say to Me in that day, 'Lord, Lord, have we not prophesied in Thy name? and in Thy name have cast out devils? and in Thy name done many wonderful works?
23 And then will I profess unto them, 'I never knew you: depart from me, ye that work iniquity.'"
KJV
Again, WHICH Kingdom was Jesus pointing to in the above? His later physical Kingdom on earth that comes at His future return.
Matt 8:11-12
11 And I say unto you, That many shall come from the east and west, and shall sit down with Abraham, and Isaac, and Jacob, in the kingdom of heaven.
12 But the children of the kingdom shall be cast out into outer darkness: there shall be weeping and gnashing of teeth.
KJV
That is a direct connection to many of the Old Testament prophets about God's future gathering of the tribes of Israel, including the Lost Ten Tribes. The majority of Israelites to this day are still scattered among the Gentiles, living as Gentiles, thinking they are Gentiles. That gathering is still future to us, and will be done by Lord Jesus Christ at His future 2nd coming. That's about the future physical Kingdom obviously.
Matt 13:40-43
40 As therefore the tares are gathered and burned in the fire; so shall it be in the end of this world.
41 The Son of man shall send forth His angels, and they shall gather out of His kingdom all things that offend, and them which do iniquity;
42 And shall cast them into a furnace of fire: there shall be wailing and gnashing of teeth.
43 Then shall the righteous shine forth as the sun in the kingdom of their Father. Who hath ears to hear, let him hear.
KJV
Only at the very END of the world (to include Christ's "thousand years" reign), will those "tares" be cast into the future "lake of fire",
Luke 13:28-29
28 There shall be weeping and gnashing of teeth, when ye shall see Abraham, and Isaac, and Jacob, and all the prophets, in the kingdom of God, and you yourselves thrust out.
29 And they shall come from the east, and from the west, and from the north, and from the south, and shall sit down in the kingdom of God.
KJV
That's another example from the Old Testament prophets about the gathering by Christ of the Old Testament saints in the future physical Kingdom when Jesus comes.
Luke 14:15
15 And when one of them that sat at meat with Him heard these things, He said unto him, "Blessed is he that shall eat bread in the kingdom of God."
KJV
What time of eating bread was Lord Jesus referring to there? The great supper in His future Kingdom. Christ's elect who reign with Him will serve Him at His table, and sit down to eat with Him. Of course that could not happen at anytime after the cross, since Jesus is in Heaven with The Father, still expecting. That is another example of His future physical Kingdom still yet to come.
John 18:36
36 Jesus answered, My kingdom is not of this world: if My kingdom were of this world, then would My servants fight, that I should not be delivered to the Jews: but now is My kingdom not from hence.
KJV
That seals it. Jesus made it plain that His Kingdom is not of this present world time, meaning His future literal physical Kingdom when He shall sit upon the throne of His flesh father David, which is an earthly throne.
So when Jesus showed the Powers of Heaven had come in full view to those Pharisees asking Him when the Kingdom should come, that was about His Kingdom by The Spirit, which IS... already here on earth today within the 'spirit' of His believers, through His many-membered body, His Church.
