Ok, Now I understand what you are getting at and do agree the world is not the Kingdom of God.
From this point of view I was speaking.
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.
I'm glad you agree and understand what I'm saying. Now please go look up the Scripture you quote and read the margin. It will show you that Yeshua was definitely not telling those murderous Pharisees (not all Pharisees were bad, but they were after His blood) that the Kingdom of God was within their hateful hearts. Yeshua was informing them that the Kingdom of God - represented by Him, the King - was in their midst. They were blind to it.
|The Kingdom of God has come already for me and all believers, its inside me.|
The Kingdom of God has not yet come, not even for believers, but it has been germinated in the lives of those who will be born again and enter the Kingdom of God when He returns and reigns and we're transformed at the First Resurrection.
We will be divine Spirit-Beings, no longer subject to sin or death. Presently we're still flesh and blood and far too human but when we're truly born again we'll be Spirit as God is Spirit.
Herbert W. Armstrong used to teach the Church of God is the Kingdom of God in embryo. Excellent analogy!
The whole world will be surprised when the Kingdom of God, the Nation of God-Beings, is instantly born before their very eyes, in the twinkling of an eye, blind to our process of conversion but witnesses to our literal transformation at that time from human to divine, from flesh and blood to brilliant Spirit.
Who has ever heard of such a thing? Who has ever seen such things? Can a country be born in a day or a nation be brought forth in a moment? Yet no sooner is Zion [Church of God] in labor than she gives birth to her children.
