Most all you say is true. Yet, you are talking about mystery.

Yes. Jesus used parables to give us some understandings of those mysteries. Yet, they remain mysterious.

I've researched the word "in" and "within" quite a bit. It has opened up my understanding... well gave me some understanding that I never had thought about before, but still, that it remains ethereal and mysterious...

My continuing opinion is - the way I look at this is -t hat the kingdom of God (Jesus) is among us and the new creation is within us with complete access to Jesus who is with us...

Anyways, I, again, recently ran up against a wall and, again, looked the words up at biblehub.com, looking for reinforcement, substance, and clarity... looking through that darkened window of my physical brain...

At that site itself ,the search went Bible > Strong's > Greek > 2080
