And there is yet another... ABUSE of Bible Scripture, trying to use Apostle Paul's teaching in Ephesians to say that Christ's Kingdom is NOW... when he/she doesn't really know what this present world and Christ's Kingdom is about!
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
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
If the diligent Bible student looks up the Greek for that word "within" that Jesus said, they will discover it literally means 'inside' you. What was Lord Jesus pointing to by saying the kingdom of God is 'inside' us??
Put 2 + 2 together, He said His Kingdom is NOT of this present world, and He said the kingdom of God is 'inside' us. What's the result?
His Kingdom is of SPIRIT, and that how His Kingdom manifests 'inside' those of His that believe on The Father through Jesus Christ, via our 'spirit' that is inside... our flesh body. We are NOT really flesh, we simply have... a flesh body that 'we' live in upon this earth. Our REAL person is made up of a spirit with soul attached to it (Matthew 10:28; Ecclesiastes 12:5-7). When our flesh body dies, it goes back to the earthly material elements where it came from. But our 'spirit' goes back to God Who gave it. And like Paul said in 2 Corinthians 5, to be absent from the body is to be present with The LORD.
The world to come... will be one of SPIRIT also, and THAT... is when His literal physical Kingdom will manifest upon THIS EARTH.
But until that future world to come, today Christ's Kingdom is ONLY 'within' His servants by The Holy Spirit! A Church building is NOT His Kingdom, nor is a seminary or monastery His Kingdom, etc. Nor will some men's attempt to build a NEW WORLD ORDER one-world government today be His Kingdom. JESUS MUST RETURN to begin His future Kingdom.
NO physical KINGDOM of the flesh is Christ's Kingdom today.
As a matter of fact, per Lord Jesus' warnings about the very end of this present world, He told us to beware if someone comes up to us and says something like, "Lo, Christ is here, or there". Jesus said to "believe it not" (Matthew 24:23-26). That is because a false-Messiah is coming FIRST to play Christ and deceive those who allow it. And that is for THIS PRESENT world.
