I’m convinced “the kingdom” is not necessarily for after we die, but for here and now.
It’s a way of looking at things that brings fruit of the spirit to any situation no matter how terrible the environment or how terribly evil “other people” are. It’s that “place” where the first are last, and the greatest is the one who serves. It looks and feels like the same earthly place as not being in the kingdom, except without the judgment and anger and anxiety.
Note that Jesus talks to His disciples as if they know the mysteries of the kingdom and others don’t. This implies there is something about the kingdom, beyond knowing all of Jesus’s stories and parables, that one sees once one “enters into” it via becoming born of the spirit. Kind of a fancy way IMO of saying that a person has lost his/her worldly illusions and is seeing with eyes of Truth, through having ingested and put to use, His teachings and sacrifice. :bible1:
Note the bolded lines below; they support my case that one can “know the kingdom” while still on this earth. Because some actual walking and talking human beings who were His disciples, had this knowledge. So it isn’t just for “us after we’re dead.”
The fact that many prophets and righteous people have not seen it, tells me that it is something other than Just Good Behavior that gets one to this point where Jesus can talk to us directly and not only through parables.
Matt 1310-17
The disciples approached him and said, “Why do you speak to them in parables?” He said to them in reply,
“Because knowledge of the mysteries of the kingdom of heaven has been granted to you, but to them it has not been granted. To anyone who has, more will be given and he will grow rich; from anyone who has not, even what he has will be taken away. This is why I speak to them in parables, because ‘they look but do not see and hear but do not listen or understand.’ 14 Isaiah’s prophecy is fulfilled in them, which says:
‘You shall indeed hear but not understand,
you shall indeed look but never see.
Gross is the heart of this people,
they will hardly hear with their ears,
they have closed their eyes,
lest they see with their eyes
and hear with their ears
and understand with their heart and be converted,
and I heal them.’
“But blessed are your eyes, because they see, and your ears, because they hear. Amen, I say to you, many prophets and righteous people longed to see what you see but did not see it, and to hear what you hear but did not hear it."
